The following article documents the spontaneous recording of Electronic Voice Phenomena (EVP) in an experimental physical séance circle. It is a personal attempt to investigate and understand the nature of the voices. The initial focus was to determine the source and validity of voices obtained on digital recorders during séances and to investigate their concurrence with sitters’ reports of visual phenomena. As yet, it has not been possible to determine a source that would explain or replicate the phenomena.

The Furzey Hill Physical Circle was formed to explore the validity of physical séance phenomena. From 2005 to 2008, members changed intermittently and the reported phenomena varied from sitting to sitting. Whilst very occasionally, a partial materialization was reported, more common phenomena such as fleeting lights and noises were reported with regularity. In May 2008, I was gifted an Olympus VN2100 Voice Recorder. I sat alone and made a recording of 38 minutes; it has some of the clearest voices captured so far. The most startling are two elderly women; one has a distinctly upper class English accent,v1 the other has a regional London accent.v2 Expecting the recorded voices to be an isolated occurrence, I took the recorder into the next sitting. Not only were there multiple voices present, possibly the same elderly lady could be heard.v3

Some group members were very concerned that a study of the voices would de-focus the group from our original goal of developing physical phenomena. A fixed study period from August 2009 to March 2010 was agreed after which we would return to our original focus of sittings.

The Séance Circle and Reported Phenomena

The group regularly consists of three members including me, who acts as the medium. Members are not religious but the group sits as a Spiritualist circle; however, there are three important departures from the traditional physical séance; the use of continuous red light, no use of music or singing and I do not enter a state of trance.

There is one source of light in the room, an overhead fluorescent globe with a 60-watt red bulb. This is controlled by a dimmer switch, which is out of the reach of sitters and the medium. In one corner of the room, there is a black-curtained cabinet. In sittings, the curtains have an aperture at the front of approximately two feet, allowing the sitters a clear view of the medium. Blackout blinds are placed at the window and cover the recessed doorway, successfully eliminating all daylight. It was agreed that the first three sittings would be held in blackout conditions to encourage the development of phenomena.

The first phenomenon to be reported in the circle was a dull white/yellow light approximately two inches in diameter, emanating from a wall to the left of the séance cabinet – this was visible for approximately fifteen minutes. Moderate red light up to 20 watts does not appear to inhibit the generation of physical phenomena. Lights are still seen, both static and moving. They have been described as tiny pinks of color to brilliant flashes of lightning. At 60 watts, knocking, unexplained noises and EVP capture are reported but no visible phenomena. We attributed our observations to low lighting; however, coincidental EVP have confirmed many reports of lights and noises.

Figure 1: The séance room

Partial materializations were reported in five isolated sittings over the period of nine years. Transfiguration was the most common type of phenomenon commented on in EVP. An example was the voice of gentleman with a North East English accent, who said “We’re not impressed with that,” as a circle member observes many faces transfiguring in rapid succession.v4 Audible phenomena can be most perplexing; the sound of a heavy horse walking on cobblestones was centered in the middle of the room. Again, this phenomenon was never repeated. Voices have been heard in the séance room by all present but never clearly enough to understand their speech. Whistles are occasionally heard in the room, at other times they can be heard on the recording without our awareness at the time.v5

All guests sitting with us whilst a recording was made were able to identify voices on the recordings not heard in the séance room.

EVP Communicators

The communicator’s motivation to make contact and talk appears to be either out of curiosity to find out if they can be heard or to make a comment on an aspect of the sitting. They do not report being directed to make contact but do on occasion refuse to speak if they are reprimanded by another communicator. Received EVP clips do not provide evidence that communicators have a depth of knowledge on the mechanics of how they send messages but they are fully aware that they can be heard on our recording devices.

Regular members have received no communication from families or friends. Personal messages to members are purely centered on the phenomena within the circle. Some communicators express an ability to follow a member away from the group but have no function other than to observe their actions. They express little interest in assisting with our development but are entertained by our endless fascination with them. At no point has the circle received regular messages from a group of communicators that perform as guides to facilitate development.

Regular communicators have distinct accents and often repeat the same phrase, almost a vocal calling card. Many are willing to give their name, but when asked for personal information that would satisfy us of their identity, it is not forthcoming. We rarely capture messages telling us how or why the communicator died or a matter pertaining to their death, it does not seem important to them. At odds with this are EVP from field recordings, where EVP is more likely to make reference to death and dying.

Séance Recordings

Up to four laptops were used to analyze each recording; all are standard unmodified machines, each running Audacity 1.3 beta (Unicode), which is an open source sound editing platform. Four digital recorders are used; two Olympus VN2100, a Sony ICD-B600 and an Olympus LS10. External microphones were not used. After the sitting, data is immediately transferred from all devices to Audacity in real time. Direct file transfers were only possible from the Olympus LS10; these had fewer voices versus the same recording transferred via a cable.

Once clipped, isolated EVP are played as soon as possible to those who attended the sitting; it is important that reviewers have a fresh memory of the discussions held in the séance. Depending on our understanding, EVP clips are then graded into three categories; A: clear and easily understood by most listeners, B: understandable with repeated playing or earphones and C: difficult to understand speech or a noise not heard in the séance room at the time of recording.

The ability to obtain EVP on four digital audio recorders and on three laptops illustrates the phenomenon is not an inherent or idiosyncratic anomaly to one device. When used together, both Olympus VN2100s were capable of picking up the same voice, at varying levels. Only two voice clips were captured on the Olympus LS10 at the same time as a VN2100; although audible, they were Grade C clips and not easily understood. I prefer not to artificially modulate isolated EVP, so it is necessary to learn the patterns of stress, pitch and inflection before attempting to interpret each message. There are examples of very clear but meaningless EVP in our archive, these are excellent in training your ear for analysis but purposeless in their content.v6

EVP comments can be seemingly random, nonsensical and grammatically incorrect. Single words are often spoken in isolation and it is rare that we capture more than a short sentence. Foreign clips are captured infrequently; those that could be interpreted have had meaning to the group. Without doubt, the most puzzling EVP are those of members’ voices, speaking phrases and sentences that we are certain were not spoken by us. This type of EVP is nearly always clear, although characteristically incorrect in comparison to their normal vocal profile and use of language.v7 We discussed in the circle how our voices could be manipulated; we were surprised to hear the reply, “Then I change the waves.”v8 EVP comments hint that existing sound waves in the environment are morphed to convey the message of the sender.

For some recordings in 2009, the in-between station noise from a short wave radio set at 5 MHz was tested as a carrier wave for voices. These sittings were outside of the specified study period and its use did not increase the capture of the voices, it was therefore discontinued.

The Study

There were a total of twenty-one sittings within the study period. Recordings were reviewed and a tally was made of how many direct responses or irrelevant comments were isolated. From the results, it appears that relatively few direct responses were captured in any one sitting, but if considered overall, eleven percent of the total number of EVP clips were of interest. It should be noted that a number of these clips were grade C and therefore an unpracticed ear may well arrive at a less impressive figure.

“Great big flash on your head” –“That bastard saw me.”
Figure 2: Audacity waveform of clip v10

As well as looking at the amount of direct responses, I was keen to establish if EVP could be captured on more than one device at a time. In the sittings where two recorders were used, there are examples of the same EVP present on both recordings. Whilst these clips are significant there are relatively few; further duplicated recordings are taking place to try to replicate the results.

Whilst the study provided a focus for critical listening; it did not address my subjective interpretation of the EVP. I wanted more certainty that the clips I translated would be commonly understood by a wider English speaking audience and I was concerned that my interpretations would lead to selective reporting and bias. I chose to perform an online listening survey to compare my interpretation of EVP versus a test subject. Participants were directed to the two-part survey through the group website.

Before beginning the survey participants were asked to declare if they believed in the possibility of afterlife communication, if they were a non-believer or if they were undecided. In part one, they were asked to interpret a mix of a series of 8 Grade A, B and C clips from the archive. In part two, they were provided with a translation of the same 8 clips and asked if they agreed with our interpretations.

It was tempting to present only class A voices, those that are most easily understood, however, I considered that a range of clips requiring varying levels of auditory acuity would provide a more realistic appraisal of interpretative skill. All groups were more inclined to attempt a translation if they did not agree with the provided interpretation.

In part one, no group or individual was able to interpret the clips which had an unusual speed – yet I had found translations easy. The remaining clips were more like everyday speech; test subjects found them easier to understand. I consider the survey to have been personally helpful even if the outcome was somewhat predictable. I cannot assume to provide an agreed interpretation for all voice clips but am confident that the translations I provide for grade A clips are likely to be agreed with by other listeners.

Direct Response Examples

(Clips not available) The first recording took place in May, 2008. By December, 2008, EVP clips with direct relevance to the circle were building. I consider a direct response or comment to be a voice other than ours that answers a question, makes a remark concerning the action of a group member or a valid observation of something taking place within the room. I was keen to understand how much awareness the EVP senders had of our environment.

I have provided the transcripts of three clips that I think illustrate well the communicators’ ability to both hear and see what is happening in the séance room:

Clip 1. My voice: “Down there,” EVP: “Big flash.” A circle members says, “I saw a big white flash.”v9

Clip 2. A circle members says, “Great big flash on your head.” EVP: “That bastard saw me!” v10 (See Figure 2)

Clip 3. My voice: “There’s a group of chaps and all standing there talking.” EVP: “Is anybody saying they think of us?” v11


The ability to capture a voice on more than one device at the same time may indicate that the EVP is a recorded transmission of a physical sound wave and not a mechanical or electrical fault inherent to a recording device. This does not in itself provide evidence of an incorporeal source but it does suppose a source of physical generation. It also leads to the unanswerable question; how would an etherical intelligence commute thought to a sound wave that is able to be recorded at the same pitch and volume as human speech but that is not heard in the environment at the time of recording?

It would be logical having only read the study results to conclude that EVP does not provide evidence of post mortem communication. However, had you taken part in a sitting, witnessed the recording and were satisfied that no deception took place, then on playback were able to hear an anomalous voice in reply to yours, it would be logical to explore all alternative explanations, regardless of how unlikely they were. We are fortunate in continuing to experience and report physical phenomena and EVP in our sittings; the study and recordings will continue.

[Editor: EVP will “normally” occur in only one recording process at a time. An exception is if the noise output device has an analog stage. In that case, it is possible the EVP could be formed there and recorded by more than one recorder. With this exception, the one process-one EVP characteristic is so dependable that it is used in the Control Recorder for EVP Best Practice:]

4Cell EVP Demonstration

by Tom and Lisa Butler
(Based on a Summer 2005 AA-EVP NewsJournal article) Updated May 2015


Can discarnate personality communicate with people in different parts of the world by hearing (sensing) a question from one person, ascertain the correct answer and deliver that answer to someone else in a different part of the world? A series of EVP sessions based based on a specific protocol were conducted by four person teams. Coordination was via email and discussion board, and team members were in different parts of the USA. A person functioning as Requester thought of a question and told the question but not the answer to a person functioning as the Sender. The Sender communed in some way with his or her etheric communicators, asking them to tell the Receiver the correct answer via an EVP message. Once notified that a question had been sent, but not the question or answer. The Receiver conducted an EVP session to ask for the answer. A fourth person acting as the Scribe evaluated the resulting recordings for possible EVP and made first determination of what was said, if anything. The study indicated that it is possible to use EVP to gather information, but that there are limits to the kind of information that may be accessed.

Directors of the ATransC (formally the AA-EVP) had been looking for an effective has been in finding a way to make the recording of the phenomenal voices more reliable. There has also been a problem with practitioner ability, which varies considerably amongst people willing to participate in such studies.

One initiative to increase our understanding that has proven to be very effective is the 4Cell EVP Demonstration, which was conducted by association members and tracked in the Idea Exchange. The 4Cell project is designed to function as a test bed in which new ideas can be tried and the limits of EVP can be explored. As the 4Cell demonstration matured with more cells and more experiments on record, we anticipated being able to provide solid support for the existence of EVP, and the fact that EVP may be evidence of personal survival. Further, we expect this proof to be in a form that the scientific community will be able to accept, and therefore, feel obliged to repeat the experiments.

The 4Cell EVP Demonstration protocol is explained here. As always, we are available to assist researchers in setting up Cells to meet their research goals.

It is possible to apply this protocol to mediumship studies as well.


Each cell consists of four people:

  1. A Requester who thinks of a request to be given to cooperating etheric communicators. A request may be a question, such as, “Who was my favorite teacher,” or a request for action, such as, “Please tell the Receiver what I am wearing now.” The request should be of interest to the Requester. The request can be directed at a research question, such as, “What happens after the moment of physical death?” The Requester tells the Sender the request but not the expected response.
  2. A Sender who is given the request and then conveys it to his or her etheric communicators, asking that they send the requested information to the Receiver. This may be accomplished in any way the Sender feels will work. Part of the objective here is to allow the participant to invent a way that “seems” right. Since so much of this is intuitive, personal initiative may be more effective than constraining rules. If there is doubt as to how to proceed, we advise that the Sender meditates or contemplates on the question. The idea is to send the message psychically, but to also send it verbally and maybe even in writing. All are effective techniques for EVP, as all helps focus attention. The Sender then notifies the Receiver that a request has been sent.
  3. A Receiver who conducts an EVP session (or contemplates/meditates for mental mediumship), asking to receive the response to the request. There may be many receiving sessions and they may be designed to suit the Receiver. To maintain focus, the Receiver should be the only one conducting a receiving session for any particular cycle. If the Receiver thinks EVP are in the resulting recording, the sound files are sent to the Scribe. (Mediumistic messages should be prescreened by the Receiver for a sense of meaningfulness.)
  4. A Scribe who accepts what was received, if anything, from the Receiver and makes a first determination as to what is said. The Scribe then asks the Requester for the request and privately posts the request and possible responses to the other three members of the Cell. The results of collaboration amongst Cell members is documented in a standardized report. For ATransC sponsored Cells, the report is posted on the Idea Exchange for peer review.
  5. Other board participants are then asked to consider the offered response by functioning as a listening panel. The Cell’s determination of what is said remains as The Report, but comments from others are retained as a record of possible alternative considerations (peer review).

Cell members have been asked to rotate positions, but we have found that it is more important that the cell has some degree of recording success so we are now asking that each Cell has at least one experienced experimenter with some level of confidence that at least some messages will be recorded. The Cells were also asked to record on a regular, weekly basis but now we see that there are too many normal living interruptions. It is better that the group tries to record when possible, perhaps on a monthly schedule.

It is important that some recording schedule is maintained, otherwise, the normally geographically distributed group of people tends to lose focus resulting in eventual abandonment of the study.

Once an effective Receiver has been found and the Cell has had some initial success, rotating members into the Receiver position will help develop more overall ability of the group.


In the event that one of the four members is temporarily not able to participate, the functions of Receiver and Scribe can be combined. But separation between the Requester and the Sender is required to address the possibility that the Requester is asking something that is emotionally biased. This also separates the expected response from the send/receive process. The reason the Scribe is asked to independently decide whether or not the request has been correctly responded to is to see if he or she is able to arrive at that conclusion without the influence of group-think unconsciously guided by the Requester.

The protocol does not require a specific type of question or technique for obtaining the answer. The reason for this is that the group dynamics are as much part of the research question as are the resulting answer. One of the predictions from this protocol is that a cooperating group will have better results than one that experiences internal conflict. The concept is that the rapport of mutual cooperation builds the kind of contact field thought to be necessary for trans-etheric influences.

The flexibility of the protocol is in the fact that the Receiver can use EVP, automatic writing, mental mediumship, any form of transcommunication.  If EVP is not used, then the Listening Panel can be referred to as something like a Witness Panel.

Evaluating Results

Since Cell members are usually scattered around the country, it is unrealistic to attempt physically supervising the experimental cycles: so many experiments by many different Cells over many months should provide sufficient information to assess the validity of the concept, even though individual results should be judged on a case by case basis.

Responses are seldom going to be decisively correct and many requests will require a subjective response. For instance, A possible answer to “Please recite Mary Had a Little Lamb” might be a verbatim recital, but more likely would be more arcane such as Lamb chops, Happy Mary, or baby sheep. As such, the determination as to whether or not the answer is correct must be made on a scale of reasonableness and the unlikeliest of the results. This is why the first decision is independently made by one person and that decision is preserved in the record.

After the Scribe sends the first determination to the other Cell members, the group collaborates to accept, modify or completely change that first determination. The results of this process are also reported.

Finally, the use of an independent Witness or Listening Panel of less invested people helps to avoid group-think. This final review of what the Receiver reported is most effective if one of the Witness Panel acts as a Judge to sort out potentially divergent opinions.

The three versions of the transcommunication: Initial determination by the Scribe; Cell member’s group determination; and, the version selected by the Judge are retained in the report record. Confidence in the usefulness of the answer is based on this report.


At first, the effectiveness of the protocol was unknown; however, early Cell reports made it clear that the communicating entities were happy to participate and that they could do all that we asked.

4Cell 1 – Voices: Andrea Carr, Siobhan McBride, Karen Mossey and Sue Mousseau (James Jones replaced Sue in experiment four and then the group dissolved):

  • Experiment 1 question: “Does it take more of your energy to manifest a Class A EVP, and if so, please indicate your answer as ‘More energy’ or ‘No difference.’” Class B answer: “No difference.”
  • Experiment 2 question: “From what level in the Afterlife are you communicating with us?” Class B answer: “Level six.”
  • Experiment 3 question: “What can we, as receivers on the physical level, do to help facilitate communication from you, the transmitters in the spiritual?” Class B+ answer: “Just open up the portal.”
  • Experiment 4 question: “What is the purpose of our communication with the other side? What is it we’re supposed to be doing in order to help them?” There was no appropriate response recorded.
  • Experiment 5 question: “Can anyone (any dead former human being) on the other side be involved in EVP messaging to us?” Class C answer: Four distinct utterances in same file, the second being “Perhaps.”
  • Experiment 6 question: “Is there a reason that some spirits do not come through for us? Why would that be?” Class B answer: “Stop moving” and “That’s right.” Class B- answer: “Yes … people.”

4Cell 2 –Infinite: Mary Jo Gran, Rheta Conley, Shelly Morrison and Vicki Talbott:

  • Experiment 1 question: “Can you tell me the name of Jim Robinson’s make believe sister?” Correct answer: “Sissy Sally.” Class B answer: “Sally’s the name.” (Other appropriate answers were also recorded.)
  • Experiment 2 question: “Who is the artist and what is the name of the painting hanging at the end of the entrance hallway in Vicki and Pete’s home?” Correct Answer: “Marc Chagall” and “The Lovers.” Class B answer: “Who painted it? … Chagall did.”
  • Experiment 3 question: “What Did Keith’s Grandpa Hallmark give him, and also, it has been lost. Can they tell us where it is?” Correct Answer: “Cue stick.” Class C answer: “A cue” and “Christy know right where it is.
  • Experiment 4 question: “What are the names of Jim’s Montessori School teachers?” Correct Answer: “Vivian” and “Rosmund.” Class B answer: “Vivian.” Class C answer in same file: “Rosmund.”
  • Experiment 5 question: “What is the most common sign that those in Spirit do to let us know you are near us or that you have been around?” Class C answer: Not clear.
  • Experiment 6 question: “What was the name of the tavern where I (Vicki) met my husband?” Correct answer: “The Waterfront.” Class B answer: “Has a view of the bay.” (below)

Cell Name: CellOctetic

Demo 3 Question: “What were some of your misconceptions about death and/or life on the other side?”

Answer: Vicki told us that, “Braden (her son) wanted us to know that the answer ‘Regrets’ was a very difficult one for him to give.” The order of the EVP that was most important to the study  was: Class C “It’s just hard to answer this,” Followed directly by Class A “Regrets.” (below)

Vicki explained: “I think that he and his friends on the other side did not want to hurt their moms or frighten others—they discussed whether Braden could even say it. He knew I could handle it, but others might not be able to. The EVP came as you see it above. As I said, Braden wants us to know that this is an important part of our passing; our life review.”

Comment: Near Death Experience researchers appear to be in agreement that we do experience a life review, and that it is from the perspective of those with whom we have interacted during the lifetime. This review can be expected to be emotionally painful, but it is probably the foundation on which we build new spiritual understanding. The 4Cell results are amongst the very few we have seen indicating all is not heaven when we make our transition.

4Cell 2 –Infinite: Shell Morrison: “Review our lives”  (below)

Shell was functioning as the Sender during a 4Cell EVP Demonstration experiment, but when the Receiver did not record an EVP that was appropriate to the question, “What happens when we die?” she asked Sell to record for answers. Shell recorded this response, which is an astoundingly clear Class A.


Of the first eighteen experiments, eleven or 61% were seen as successful. The etheric communicators have had a very large number of possible answers from which to choose. For instance, in Cell Infinity’s experiment 4, asking for Jim’s Montessori School Teachers, the expected answer was given as “Vivian” and “Rosmund.” How many first names are there in the western culture? There must be thousands. The odds of a person guessing the correct name must be about the same as winning the California Lottery. What are the odds of selecting the right name twice in the same EVP?

Guessing eleven appropriate answers out of eighteen attempts must be similar in difficulty to winning the California Lottery eleven out of eighteen tries. The results of the experiments would be astounding just because of how much the answers have exceeded what would be expected for guessing. Since we know that the communicators are intelligent, aware people, the gratifying part is not beating the odds, but how cooperative they have been.

We wish to thank all of the Cell members for their participation in the experiment. We especially thank Shelly Morrison and Vicki Talbott for moderating the Idea Exchange forum and for helping everyone get through the complicated protocol. And yes, a hearty thanks to their etheric partners who have been so willing to help us learn.

Eliminating Radio Frequency Contamination for EVP

by Bill Weisensale

The most common explanation for the source of the voices in EVP that is offered by people who have not studied the evidence, is that they are caused by the audio recorder picking up stray radio or television signals. In fact, a number of well-designed experiments have been conducted over the years by very qualified people, to prove that such stray radio frequency signals are not the cause. Reports of two such experiments are provided below.

There is also an experiment shown below that was suggested by one such scientists as a prerequisite to his accepting that EVP are not stray electromagnetic (EM) signals. We believe that nested metal containers, such as the variety found in hobby stores, separated one from another by foam rubber or Styrofoam, would satisfy the requirement while helping to rule out stray sounds.

From the AA-EVP Archive

Here is longtime researcher Bill Weisensale’s response to concerns expressed by Dr Karlis Osis, with the American Society for Psychical Research, about eliminating mundane causes for EVP. From Bill Weisensale’s article in the May 1981 Spirit Voices:

In early 1975 … the controversy was still raging as to whether EVP voices arrived via acoustical or electromagnetic means. (It is generally accepted now that neither is the case.) At the time this was most perplexing. It seemed reasonable to believe that if EVP arrived by electromagnetic signal, a radio receiver would be required in all cases, and yet some methods did not involve any form of radio receiver. Conversely, if they were of an acoustic nature, then all methods would, of necessity, require the use of a microphone, and yet there were some methods that do not involve a microphone.

I reasoned either the voices had to be both acoustic and electromagnetic, depending upon the method of recording, which seemed very unlikely, or they had to arrive by some other kind of energy, which was of neither electromagnetic nor acoustic in nature. (We have come to call this PK energy, for lack of a better explanation.) In order to find out which was the case, I used a (steel) 50 gallon drum with a removable lid …

I brought the drum into the house, laid it on its side on a wooden pallet, and blocked the sides to prevent it from rolling. Next, very small holes were drilled in the drum and lid. A piece of heavy wire, with a solder terminal, was then bolted to the drum and run out through a window where another solder terminal and bolt were used to attach the wire to a steel stake driven into the ground. A second wire and solder terminal was attached to the lid and soldered to the first wire. All connections, drum to wire, lid to wire, wire to wire, and stake to wire, were checked with an ohmmeter to ensure there was no resistance and everything was properly grounded. Before doing the experiments, water was poured around the steel stake to ensure proper grounding.
spirit_voices_1In the initial experiment, which was to check the efficiency of the shield, a battery powered radio receiver was tuned to a strong station, the volume set rather high, and placed inside the drum. A battery powered tape recorder was then connected via patch cord to the radio, also placed inside the drum and the lid bolted into place for several minutes.

Upon removing the recorder and reviewing the tape, it was found that the station was quite clear with the lid off, but when the lid was bolted into place, the station totally disappeared and its presence could no longer be discerned even with the closest listening. We then adjusted the radio to between station static, listening carefully to be sure there were no distant stations present, placed the radio in the drum with the recorder and made several recordings with the lid bolted in place each time.

We found the voices appeared inside of the shield just as they did with no shielding. Also, since the radio and recorder were connected via patch cord and there was therefore no microphone involved, this experiment eliminated (to at least my own satisfaction) both the acoustic and the electromagnetic hypotheses.

[Editor: The May 1981 Spirit Voices and other newsletters are being added to the AA-EVP online document archive as time allows. We are currently up to Spring 1987 with the AA-EVP newsletters. Remember that access to the Archive is a benefit of membership. We highly recommend that you take advantage of this growing library of historical EVP and ITC documents.]

A Suggested Experiment

Initially published in the Fall 2004 AA-EVP NewsJournal

ccaaevp2008-shielded_suggested_by_charles_tartParapsychologist, Professor Charles Tart, was interviewed by The Psychic Times (apparently defunct), a new British publication that is already proving itself antagonistic to EVP. In the article, Tart was quoted to argue that EVP is stray radio, and that we who study in this field have not demonstrated the necessary research discipline to produce the kind of credible evidence that he can take to other scientists.

The diagram is of a shielded recording compartment, EVP from which would answer Tart’s objections. It provides more shielding than a metal can or microwave, but it is not as readily available. We would like to talk to someone who might be able to make one, or who might have one. If possible, we would like to send one to a number of different experimenters in serial fashion, so that many examples can be collected in the compartment. Please let us know if you can help.

Report of an Electronic Voice Phenomenon Experiment
inside a Double-Screened Room

By Alexander MacRae


An Electronic Voice Phenomenon (EVP) experiment is described which took place in a laboratory screened against e.m. radiation and also acoustically isolated. The subsequent treatment of the results through sound-processing is outlined, and the final analysis of the results through the use of a unique multiple-choice system is described. Comparative spectrograms of one EVP utterance and the same thing spoken in normal speech are provided to assess the physical basis of the results. The conclusion is drawn that voices of no natural origin were received in the screened laboratory.

Recording Thoughts of the Living?

by Lisa Butler
Originally printed in the Spring 2001 AA-EVP NewsJournal

There is some evidence that at least a few of the messages we record in EVP, may actually be put there by people who are still in the physical.  Here are a few examples from members:

  • In the Spring 1982 newsletter, Sarah quoted Tina Laurent of Wales:  “I’ve had on two occasions, voices that sound exactly like two people I know, they gave their names too, but they are STILL living.  I don’t know what to make of that.  Do you?  One of them I played for my brother and his wife and they recognized them straight away and they have always thought that I played a joke on them.”
  • Ernst Senkowski contributed this: “I several times observed at least the name and possibly the voice of a living person some 300 miles away. . .(A) case seems to have happened in Italy wherein an EVP experimenter succeeded in taping the contents of the mind of a far absent living person.  So we have to be very careful in stating ‘our’ voices come from the ‘dead.’”
  • Jacque Blanc-Garin of France recently wrote to say that, “About the problem of voices from living persons.  I tried some experiments regarding this fact.  I called some persons (my wife and some other friends with their agreement – important point for ethics) who were sleeping.  I received many messages where some were a proof. For example, I asked my wife where she was?  Answer: I am in the air, Monique. Another question: Do you meet your family on the other side?  Answer: I meet all but I will come to you because I love you Poupoune. (The name Poupoune is the nickname given to Monique by her parents).  That means we have the possibility to tape the voice of a person who is sleeping, because we go out of body while some part of us is asleep.” (See below)
  • Edna Drake, B.C. Canada, comments that she has reason to believe an EVP message she received was from a brain damaged friend of hers.  She wrote that, “I just had a strong feeling that the “voice” trying to form words stammering and stuttering, like a handicapped person, was in fact the brain injured young man I worked with for over 2 years–to talk and communicate.”
  • Brian Jones, WA, has discussed the possibility that he might actually be recording his thoughts.  He sent us a sound track in which a person was speaking to him via his computer phone at the same time he was recording.  He indicated that he thought the voice he recorded might have been generated by thoughts from that person.

You may want to test this idea for yourself by following the technique used by Jacque Blanc-Garin.  It is an interesting idea, the possibility that we sometimes record the living as well as the departed.  We are Self living in a physical body during this lifetime.  When free of the encumbrance of our body, perhaps during sleep, we are very much the same as the discarnate entities we seek to communicate with.  If this is true, then it is not much of a leap in logic to think we can impress messages on tape as well.

French Sleep Experiments

Jacques Blanc-Garin of the French EVP/ITC group, Infinitude, provided us with a description of experiments to contact sleeping people via EVP.  See more about Infinitude at ©Jacques Blanc-Garin – All Rights Reserved

From 1994 to July 1995, Jacques conducted a series of experiments in which he tried to reach people while they were sleeping.  A friend of his, Robert Doré, had suggested that it might be possible for a person to communicate through Tci (French term for ITC) with a sleeping person.  (The following is a translation from French.)  Jacques wrote, “My idea with these experiences is that we would be able to help people who are considered insane.  It would be possible to contact them when they are sleeping and maybe record the entity who is disturbing them.  However, I have not tried this because it is not easy to bring such an idea to hospital personnel.”

The following experiments were conducted with a Marrantz CP430 equipped with a micro Monacor ECM 600 ST or a Philips 6350 recorder.  For ambient noises, Jacques used the sound of rubbing paper, German language conversation, and sometimes an air-band receiver.

Jacques writes that the results were conclusive almost every time.  He also pointed out that, as a matter of ethics, each experiment was prearranged with the person who would be addressed while they slept.

Following, are samples of what was received during some of these experiments.

Excerpts from recording of Monique Simonet during sleep, April 7, 1995.

Jacques: “It is useless for me to explain to you how to make Tci.  I believe that you are more expert than me in this domain and you will know how to use all vibrations that I can send you.”
     Answer: “I would like to make it on the Earth” (very audible whisper).

Jacques: “I hope that I do not disturb your sleep.”
     Answer: “It was foreseen, I will remember” (whisper).

Jacques: “If you answer me, you are maybe in the environment where I record.  If that is it you can then tell me what I currently hold in my left hand?”
     Answer: “It is a crystal” (whisper).

Jacques said that, “I indeed, had a crystal in my hand.  Monique saw me!”

Excerpt from recording of Monique Laage during sleep, Nov. 8 1994.

Jacques: “I call this double astral body that should be theoretically able to answer me.  Are you there, Monique if it pleases you?”
     Answer: “I am in airs, Poupoune” (audible whisper).

(Editors: “Poupoune” is pet name given to Monique by her father.)

>> Excert November 10, 1995 recording Monique Laage.

Jacques: “When you go to the astral, do you meet other people?
     Answer: “I see them all again, but I will come back, I like you, Monique who likes you” (uninterrupted, whisper).

Excerpt December 10, 1994 recording Monique Laage.

Jacques: “It is extraordinary that, in a little time, you are going to wake up and you are going to return to your body.”
     Answer: “One is well, it is happiness here” (whisper).

(Editor’s note:  We are spirit living in a physical body.  It is logical that we should be able to leave messages via EVP just as those who do not have a physical body do.  This should also make us think a little more about our adventures while asleep.)

Experiment – Recording the Living

This article was originally printed in the Summer 2001 AA-EVP NewsJournal

In April Sarah Estep participated with us in an experiment in which we tired to see if we could record messages from each other while asleep.  This worked out well as Tom and I taped around 10 pm PST when Sarah was asleep.  Sarah taped early in the morning while we were still sleeping.  The experiment ran three separate evenings.

On one experiment Sarah said on the tape that Tom and Lisa were asleep right now.  A loud voice says, “That’s right,” and then 16 counts later another class A message by the same male voice says, “I am.”  During another experiment Sarah asks Tom Butler, “Are you here,” and got, “He’s here, we will try to get him back.”  When Sarah asked for Lisa she got, “I’m here,” and then later, “Stop, the Lisa back.”  This is interesting, as I woke up and remember looking at the clock.  This was verified with Sarah as the time that she was recording.

During our experiments in trying to reach Sarah we recorded, “You have main contact,” and also, “Rain.”  Interestingly, we later learned it had been raining at Sarah’s house.  We asked, “Where are you Sarah?” The message came back “I am here.”

An interesting side note in all of this. Sarah also had a surprise visitor.  During our running of these experiments Sonia Rinaldi, EVP researcher in Brazil, sent Sarah an Email.  In it she told Sarah about a very vivid dream and wrote, “I could see you so clearly that I am sure that we really met.  I was in your kitchen. … The fact is that I never remember any of my dreams.”  Sonia was not aware of our experiments and yet she had this lucid dream on one of the nights that we were trying to reach Sarah via tape recorder.

The Work at Il Laboratorio

Introducing Il Laboratorio

It is a great pleasure and honor for me to attend this very important International Conference and I wish to thank Lisa and Tom Butler for their kind invitation to participate. I will begin by explaining the targets, methods and research activities carried out at Il Laboratorio – Interdisciplinary Laboratory for Biopsychocybernetic Research, the purpose of which is to study phenomena that, for a long time, we all wrongly judged as “paranormal.” [Il laboratorio is no longer operational.]

To begin, I would like to draw your attention to the name of our organization so that you understand the leading criteria of our scientific activities. The first word, “Il Laboratorio” (The Laboratory), is self-explanatory and refers to a place provided with equipment for scientific research. The word, “Interdisciplinary,” indicates that our research is performed using methods belonging to different sciences and/or disciplines linked together in a methodological and conceptual way. To follow an interdisciplinary approach in the investigations has today become a necessity of contemporary scientific thought, particularly when the research is designed to understand certain phenomena emerging from the human mind.

The Il Laboratorio team intends also to investigate unusual occurrences; usually referred to as events that go beyond psi-cognitive and psychokinetic phenomena, in areas that traditional parapsychology did not intend to investigate. Our area of interest also includes study of so-called “borderline phenomena,” such as Out-of-Body-Experiences (OBE) and Near Death Experiences (NDE), as well as phenomena that depend upon altered or modified states of consciousness like sensitiveness and mediumship.

Our research is also concerned with investigation of the subjects involved in psychic phenomena from the neuro-psycho-physiological point of view, in order to bring to light possible interconnections between the subject and the final link in the phenomenological chain, like physical psychic effects. This includes the so-called bioresonance phenomena that are concerned with the interactive interface that man has with his immediate and more remote physical surroundings, as well as with his social psychological background.

The word Research refers to the studies designed and systematically implemented in order to increase our understanding and knowledge of unusual occurrences through the use of scientific methodology wherever applicable and feasible.

The final word in the name of our organization, Bio-psycho-cybernetic, indicates that our investigations are not limited to explaining psi phenomena by criteria and laws based only on physical paradigms, but by considering each occurrence belonging to a complex system whose properties can be understood by studying the whole system from different perspectives.

I wish to stress that the philosophy guiding the researchers of Il Laboratorio deals with events as they occur, whether as they appear in the physical world, or as evidence of inner or psychic experience. This neologism was suggested by the founders of Il Laboratorio and adopted with the goal of supporting a gradual revision of the terminology of parapsychological research in order to distance our discipline from the ghetto of the pseudo-sciences. Our activities are therefore both practical (in the field) and theoretical. They deal with the reliability of documented reports, the verification of reported occurrences, and the scientific and technological circumstances (including controls) within which findings are gathered.

Within the context of present scientific knowledge, utilizing where possible and feasible the most updated technologies, our researchers conduct their research.

Il Laboratorio Organization Chart

Before introducing to you the Department directly involved in Instrumental Transcommunication, I would like to give you some information about the other Departments that work together collaboratively.

The Research and Theoretics Departments report directly to the General Director while the Voice, Image and Psychophysiological Departments report to the Research Department.

Dr. Enrico Marabini heads Il Laboratorio as General Director. He also manages ad interim the Theoretics Department. This branch of Il Laboratorio handles the epistemological issues that arise from our research activities. This is a very important Department since its task is to confirm the correctness of methodology, and the procedures and interpretations attributed to results arising from the experimental activities of the research teams.

The Research Department, managed by Dr. Michele Dinicastro, coordinates all the research activities performed by the Departments.

Dr. Giorgio Gagliardi manages the Psychophysiological Department. He is entrusted with the investigations into the personality and physiology of the subjects involved in paranormal phenomena. This is a very complex topic and, at the same time, one that is of great importance in the context of both psychological and physiological interactions between the human personality and the phenomena under investigation.

The topic of Instrumental TransCommunication (ITC) is dealt with by the Voice Department, managed by myself, and the Image Department managed by engineer Daniele Gullà.

The Voice and Image Departments conduct their research activities thanks to the competence and collaboration of colleague Daniele Gullà, a skilled electronics engineer, who is an expert in electro-acoustical analysis of voices, as well as image recognition and processing. His extensive experience in these fields has allowed him to accomplish qualified legal advices for Italian Courts of Justice.

I am pleased to provide detailed information about our research including some practical and significant examples.

There are many ways to study the paranormal or unusual events relating to the survival of consciousness after death. Many operators who try to “receive” messages from the beyond are motivated mainly by emotional issues, such as the loss of a loved one, where the contents are surely more important than anything else. Other researchers, like myself, are conscious of the great importance of the topic and are studying the process by investigating the many different expressions of the phenomena. By doing so, those researchers attempt to characterize all the elements that contribute to increasing the meaning and validity of the results of experimentation. That is why I consider it mandatory that the phenomena witnessed be thoroughly investigated and that the investigations be carried out using methods and technical tools that are recognized as being suitable for scientific research.

It should be the task of the serious researcher to uncover all events that can be considered anomalous because they do not fit the established laws of physics. Only in this way will we awaken the scientific establishment to the importance of this kind of research, and only at that time will a revision of the paradigms, now considered unchangeable by science, take place.

In line with Thomas Kuhn’s thought1, we recognize that this may be a very slow process, but the only one capable of leading human society to the conscious maturity that will result from scientific understanding of new discoveries. To that purpose, together with my collaborators at Il Laboratorio, we dedicate our efforts in this way. We use the most up-to-date professional software and hardware to document all the peculiarities and anomalies that are found in the electroacoustical structure of authentic paranormal voices obtained under controlled conditions.

In this presentation I am pleased to share with you some examples of the preliminary findings in this matter.

Investigating Paranormal Voices Using Computer-Based Analysis

On 17 September 1952, Italian Fathers Agostino Gemelli and Pellegrino Ernetti reported a case of alleged anomalous communication received through a magnetic wire-recorder. The reported phenomenon attracted little attention until 1959 when Friedrich Jürgenson, a Sweden artist and documentary filmmaker, obtained the same kind of phenomenon. Intrigued by these claims, Latvian psychologist Konstantin Raudive commenced his own experimentation that confirmed Jürgenson’s results (1971).

Much research has been conducted in several different countries in order to help us understand the mechanisms governing the phenomenon. In Italy, we have an ongoing research program, named Sfinge Project, which is supported by a grant generously donated by the Swedish Helene Reeder Memorial Fund. Before dealing with the preliminary results obtained in the Sfinge Project, it is useful to provide some information about the signal acquisition and processing quality required to perform reliable analyses. See: Instrumental Analysis of EVP Collected via a Sound-Psi Interaction

To obtain voices of sufficient quality to permit analysis, the original recording signal must provide for a reasonably good Signal/Noise ratio (S/N). If the voice signal is at the same level as the background noise or lower, the chance of successful analysis will be extremely low. To obtain a good sound quality the original recording signal needs a relatively high signal/noise ratio, like that obtained through a digital recording rather than an analog recording through an audio cassette recorder.

Digital recording is obtained by recording directly onto a computer or digital audio recorder (solid state or digital tape recorder). The key difference between digital and analog systems consists in their acoustic dynamic ranges: those from digital recording systems are greater than 90 dB while those from audio cassette recorder (analog) are usually not more than 60 dB. That is why it is important to record Electronic Voice Phenomena (EVP) with a recording system that ensures that the acoustic loss of information is reduced to a minimum.

Unfortunately, we often have to work with very weak or noisy signals due to imperfect recordings. Too often poor quality microphones or audio cassette tape recorders are used and this results in a high distortion effect and makes analysis and decoding unreliable. It is worth repeating that the accuracy of analyses of the signal depends on the acoustic quality of the recording acquired.

In the Sfinge project, we used a personal computer, acting as a recorder of input signals coming from a high quality, condenser-type microphone and processed by a professional microphone preamplifier, with digital output, and a multiband signal processor. This project provides practical experimentation, under controlled conditions, involving four of the most skilled ITC operators in Italy, each working in independent experimental sessions.

We started the project with the first operator by experimenting with the typical microphone recording method, using a cassette tape recorder with built-in microphone.

The first experiment was conducted with a female operator, Mrs. Lida Russo from Livorno, Italy. She used her audiocassette recorder, which was really quite modest. Unfortunately, in the experimental sessions performed, she recorded only some voices of poor acoustic quality.

Exactly the opposite happened to our research team using a professional recording system, operated by Daniele Gullà, which served a cross-referential function. The introduction of professional recording tools to record the whole experiment brought us some unexpected and astonishing results. See: Computer–Based Analysis of Supposed Paranormal Voice

Another important check was carried out using a professional phonometer in order to survey the existing background noise during the experiment. Generally speaking, the main objection currently raised by the critics concerns the ambiguous sonority that mainly characterizes EVP material. In their opinion an ambiguous acoustic event, properly fragmented and cadenced, might be decoded as a linguistic message. They argue that when a high fidelity recording system is used, the alleged paranormal voices reveal themselves to be a simple noise, not voices. Our experimentation demonstrated exactly the opposite. The digital recording revealed the presence of voices not audible on the audio cassette recorded by the operator.

In my opinion, the primary cause can be found somewhere between the recording devices used, the existing psychological and/or psychical condition of the ITC operator, and the whole “Minds System”2 constituted by the people attending the experiment. In fact, the operator under observation was expecting good voices to be recorded by the experimenters from Il Laboratorio. Consequently, Mrs. Russo’s main expectation was the successful recording of voices on the sophisticated recording devices. These were arranged in the room by the researchers. Several times, Mrs. Russo asked Daniele Gullà if voices had been recorded on his devices; she was not worried at all whether voices could be recorded on her own tape recorder.

The great influence exerted on the device by Mrs. Russo (the ITC operator) was experienced again when our psychologist, Dr. Giorgio Gagliardi, and his assistant were ready to perform a psychophysiological examination of her. This examination requires the use of a polygraph connected to a personal computer, which records the neurovegetative and electrodermic changes occurring during the psychological test.

Before leaving his home Dr. Gagliardi checked that both devices were functioning correctly. No problems were found, everything was working properly. Once the electrodes were positioned on Mrs. Russo’s head and everything was ready for the test, the personal computer gave an error message. Several times the computer was checked and restarted but the error didn’t disappear. The most significant occurrence happened when Dr. Gagliardi returned to his home: inexplicably both the devices were found to be operating correctly, without any error!

Lastly, all of the approximately fifty photos taken with a digital camera, many of which show Mrs. Russo ready for the experiment with the electrodes positioned on her head, were inexplicably and definitively lost. It is my opinion that the stressful psychological condition of Mrs. Russo’s mind, probably due to her anxiety about the results of test, set off such occurrences.

In the following, the results of the analyses done on two very short tonal sentences are reported. The tonal sentences are saying: “ami Enzo?” (“do you love Enzo?”) and “oh mamma” (“oh mom”). It must be said that Enzo, the unknown speaker, is the name of the deceased son of Mrs. Russo.

The whole sentence \AMI\ENZO\ is uttered with a light temporal dilatation, with an evident pause between the two words. The voice is a loud, clearly audible voice, well cadenced, which was not heard by either the experimenters or the operator during the experiment. In the first sentence (duration 2.278 sec.) only the first part \AMI\E was analyzed because the word \ENZO\ was partially overlapped by the voices of people attending the experiment.

The analyses revealed several anomalies as follows:

  • Modulations of signals changing mainly in amplitude instead of in frequency.
  • Formants visibility limited to F1 and F2 only.
  • Vibrations of vocal cords detectable in short intervals only.
  • Abnormal fluctuations of voice frequency ranges.
  • Poor melodic and harmonic contents.
  • Vowels expanded in time.
  • Abnormal excitation of cochlear liquid (simulated via software).
  • The voice reverberation differs from the one existing in the room.
  • Aleatory values of vowels in I.P.A. table.
  • High content of noise and significant aperiodicity of signals.
  • Impossibility for the software to structure a model of Vocal Tract due to the low influence of overglottal organs (resonators)
  • Jitter values indicate the presence of possible dysphonias.
Spectrograms used for the analysis of the EVP examples
Example of vocal tracts anomalous

The electroacoustic measures reveal the presence of significant structural anomalies deviating from normal human speech parameters even if the sentence is uttered with a loud, clearly audible voice, apparently quite similar to the human voice. The second sentence \OH\MAMMA\ (duration 1.897 sec.) is uttered twice; the first utterance is made with a loud, clearly audible voice, while the second utterance is an acoustically very low, whispered voice, saying the same words.

A sound, similar to the one produced by pushing a call-bell (such as used on a reception desk of a hotel to call the personnel), precedes the first utterance. Nobody heard such a ring during the experiment. In the first and in the last vowel \A\ the software functions (L.P.C. and Autocorrelation) clearly reveal the activation of overglottal resonators but the vibrations of vocal cords are not distinctly noticeable.

The analyses performed on the second sentence exhibit the same anomalies as in the first sentence and in addition:

  • Abnormal trend of the fundamental frequency F0.
  • Impossibility for the software to represent the sound using the cochlear model (software simulation).
  • The voice seems to be partially structured both by voiced sounds and whispered sounds with only some structural components pertaining to human speech.
  • Formants are fragmented and apparently generated by a thickening of existing background noise.

The electroacoustic measures carried out on the second sentence confirm the presence of important anomalies in the voice structure. The presence of the fundamental frequency without the consequent vibration of vocal cords is inexplicable. It must be said that, in normal human speech, only the vibration of vocal cords generates the fundamental frequency.

The energy and the high a-periodicity of signals pertinent to vowels are absolutely unusual and detectable only in the zones affected by consonants. This unusual occurrence found in the paranormal voices is very important since it supports my personal hypothesis about the paranormal process of the generation of formants: it seems to come from an inexplicable process of local thickening of the existing background noise.

In particular, it was noted that such formants, mainly modulated in amplitude, are structured in the typical frequency bands pertaining to the vowel sounds. As a consequence – and this is a very important point – such formants, so structured, maintain unaltered the semantic content of the words in the listening phase. In addition, it was found that if some slight deviation or partial lack of signal occurs, causing the software to register an incorrect vowel sound classification, the information already existing in the listener’s brain (at the conscious or subconscious level) is able, during the listening phase, to make a suitable integration of missing parts in the input signals.

In order to exclude eventual deviations interpreted as anomalies due to the software used (Speech Filing System v. 4.6)®, a second professional software (Praat v. 4.3.37)® was used in accordance with a specific requirement in our Operating Procedure. The analyses performed using the second software confirmed the anomalies detected by the first software.

Another very interesting case of paranormal telephone voice that we have analyzed is the case involving Edna. In this regard, Il Laboratorio was asked to analyze a telephone voice sample, sent via email by Sonia Rinaldi, a well-known Brazilian operator who is also a presenter in this Conference. The sample is from an experiment carried out by recording a normal phone call, initiated by Cleusa, on Rinaldi’s personal computer. Cleusa was the adoptive mother of Edna, a young girl who died at the age of sixteen when run over by a car. The phone call lasted fifteen minutes during which Edna spoke seventy-eight times.

The experiment was made in a very original manner. During the conversation between the two ladies, three CDs, containing the utterances of phonemes pertaining to foreign languages (other than Portuguese), were simultaneously played. Using such a tone mixture as background sound-source meant that it was impossible to structure meaningful sentences in the Portuguese language that would be coherent with the topic of dialogue.

The sentence submitted for analysis was found to be half modulated over the sound-source and the other half perfectly clear of such sounds. The latter was recorded when the CD player was switched off. From the voice data provided, the second half of the sentence was analyzed, where the voice resulted without any background sound-source.

I must point out that the sample analyzed was sent to Il Laboratorio via e-mail and therefore subject to all the limitations of that means of communication. The analyses performed on Edna’s voice revealed the presence of the following structural anomalies:

  • Severe fragmentation of fundamental frequency F0 and its too much low fluctuation in frequency (found to be less than 15 Hz, while in normal human speech it ranges from 30 to 60 Hz).
  • Severe fragmentation of vocal cord vibrations, detectable in the positions of existing fragments of fundamental frequency.
  • Unusual increase in sound intensity in the high frequency bands ranging between 2000 and 3000 Hz. In normal speech, when the frequency range increases, the intensity of sound usually decreases. In our case exactly the opposite was found. It seemed to be a voice uttered affecting the soft palate area (glottal voice), or produced by a vocal apparatus of reduced dimensions.
  • Abnormal formant trends with a partial fusion of second formant F2 and third formant F3.
  • Abnormal formant bandwidths.
  • Abnormal increase of sound intensities in the third formant F3 and in the fourth formant F4.
  • The high values of Jitter and Shimmer indicate the presence of dysphonias due to possible phonatory pathologies. In particular the impulsive changes in voice frequency (Jitter) represent an indirect evidence of instability of the vocal system.
  • Abnormal speech fluency characterized by lack of voice breaks. In normal speech, the voice breaks are caused by the occlusions produced by certain consonants, or due to the aspiration/expiration of air to/from the lungs. In human speech, several voice breaks can occur depending on the length of the words.
  • Abnormal fluctuations of voice frequency ranges.
  • Poor melodic and harmonic contents.

Following the detection of such anomalies and in order to investigate further, Edna’s alleged paranormal voice was compared to her lifetime voice. The comparative analyses were carried out using a software named “FBI Image Searching”®, currently employed by the Federal Bureau of Investigation in the United States. This software has real-time image recognition capability. It can be used for any kind of images and produces extremely accurate results. This software is able to process millions of images. The computer processing involves artificial intelligence to learn directly the content of an image, or several images, and to retrieve all similar images based upon their content.

The “FBI Image Searching” software provides a tool for image matching through “One-to-One” and “One-to-Many” functions. In the investigation of the Edna communication, both functions were used for comparing the acoustic maps (images) of her voice. The “One-to-One” function provides the identification by matching a single image against another single image. The “One-to-Many” function provides the identification by matching of a single image against a database of images with no declared identity required. The single image under investigation is generally the newly obtained sample and the database contains all previously filed images.

Scores are generated for each comparison, and an algorithm is used to determine the matching record. Generally, the highest score exceeding the threshold results in identification. In our case the images processed were the acoustic maps relevant to Edna’s voice while alive and her alleged paranormal voice. By introducing an accuracy acceptance limit greater than 95%, the “One-to-One” comparative analysis recognized the acoustic map of Edna’s voice while alive in the acoustic map of her alleged paranormal voice.

In order to add weight to our research, the voice of the living Edna was added to the 908 voices existing in the database, where 229 voices belong to Portuguese and Brazilian speakers (Edna was Brazilian). With the same acceptance limit, the “One-to-Many” function provided a comparison between Edna’s alleged paranormal voice (its acoustic map) and the 909 acoustic maps of other voices contained in the database. The matching process took 7 hours to do 48,600 calculations, with the processor (CPU) working at 100% of capacity (Processor type AMD K7 operating at 3 GHz with RAM of 1 GHz). When the computer processing was completed, the “One-to-Many” function had identified the acoustic map of Edna’s alleged paranormal voice in the acoustic map of Edna’s voice while she was alive.

This was the only acoustic map that exceeded 99% similarity through the computer matching process against 909 acoustic maps.


Investigating Paranormal Images by Using Biometric Techniques

Biometrics is a scientific technique for measuring, in a direct or indirect way, the morphologic and anthropometric features of a person for identification purposes. Identification is understood to be the procedure whereby it is possible to recognize a person based on a sufficient number of references, such as the shape and sizes of the face features as they compare to the underlying cranial structure.

In legal matters, biometrical tests are often used to recognize an individual who has committed a crime or an absconder who is trying to conceal his or her identity. Biometrical testing is also used in other cases where a need exists to identify an individual. Consequently, the most frequent users of such methods are police departments, forensic medicine departments, and particularly intelligence services.

It is important to note that identification systems are not yet perfected. Depending upon the quality of the images used as a reference, the existing error rate can still be very high. For this reason, many of the technologies used today for forensic tests are not always able to offer fully reliable results concerning the identification of an individual; basically, they only establish compatibility indexes through similarity of statistical ratings.

In the past decade, major progress has occurred in face recognition systems. Many software packages have been designed with the ability to achieve recognition rates of more than ninety percent. The introduction of more sophisticated and accurate information technologies and the increased capability of computers have allowed the design of new recognition systems that utilize sophisticated and innovative algorithms in their processing systems, like Neural Networks, Wavelets and Computer Graphics.

One of the well-known methods used at Il Laboratorio is the so-called “Anthropometric Face Recognition.” The features taken into account relate basically to the distances between certain points of reference, or landmarks, also known as “Repère points”, situated in the cranio-facial structure. They relate also to the morphological somatic features of the shape of the face or parts of it. When manual or semiautomatic procedures are used, at least a dozen points are measured. Certain techniques require up to eighty points with calculations in three-dimensions (3D).

The accuracy of the measurements of dimensions on the image considered as reference and the corresponding dimensions on the image under analysis is extremely important. The smaller the variances the more evidential and convincing the resulting analysis will be.

Comparisons made at different times on the same face are unlikely to yield the same result with one hundred percent accuracy. This results from the inevitability of error in measurement, even if extremely slight. Though the measurements will always be similar, it is impossible to obtain an absolute measurement. This error relates mainly to the quality of the images that are compared.

In the investigation of paranormal images, due to their poor quality, it is essential that the software used should reduce the possibility of errors during the measurements. Today many improvements have been made in the field of face recognition so that the margin of error is significantly reduced. For the case reported in the following example, the most recent generation of face recognition software was used.

“FaceIt” is a software package used by forensic detectives in many countries as well as in many airports for the purpose of anti-terrorism prevention. It employs a complex method involving mathematic calculations on multidimensional matrixes, as well as making use of algorithms, such as Neural Networks, that operate in a similar manner to the natural neural network in the human brain.

A conventional software program may supply a completely wrong response even if only a single “bit” in the input information is wrong. On the other hand, an application based on neural networks attempts to correct the error by using previously stored information. This is very helpful with paranormal face recognition, since there always is a variable amount of background noise that makes the image unidentifiable. If the noise doesn’t completely cover the features of the image, a neural network is usually capable of producing a response by using the part of the information that is not polluted or distorted. This allows recognition of noisy or partially concealed face images. The reduction of the error rate to 0.03% increases significantly the reliability of the identification performed.

It is interesting to note that this software, while exploring a human face, picks up and learns a lot of information necessary for its identification. That computerized process is performed in the same manner that a human being scans a face for recognition.

Without going into detail, the system works in the following way:

  1. The extraction algorithm for the biometric data generates an image representing a bas-relief reconstruction of the face’s main features.
  2. The Eigenfaces algorithm, certified by MIT (Massachusetts Institute of Technology), processes the input data and the existing data in the database by generating an image constituted by a dispersion of points that allows a quick search for similar faces. The resulting images are displayed; they appear as though superimposed from various images contained in the database.
  3. The comparative analysis between a new sample image and the images contained in the database is carried out by generating an image of contours and automatically performing measurements between approximately 80 contour nodal points. These measurements are then compared to the corresponding measurements taken on the images contained in the database (a total current number of 7,230 faces).
  4. The software is also provided with an option called Reconstruct Face, which makes it possible to reconstruct original images in 3D starting from the processed data, by means of the Eigenfaces algorithm.
  5. The cross-correlation function aims at identifying the images contained in the database that are closest to the sample image. The faces displaying the highest degree of similarity, ranging from 1 to 80, are graphically presented.

The system has both a great strength and a great weakness. The strength is that recognition accuracy reaches 98%, with an ability to even recognize people in disguise (wearing a false beard, moustache, dark glasses, hats or hoods). The weakness is that, since the system is based on probabilities, it always identifies a match, by displaying the three most likely faces contained in the database. However, based on research performed in the United States on a database containing five thousand faces, the false recognition error proved to be lower than 5%, and was therefore considered as acceptable.

The Castagnini Case

In 1992, Massimo Castagnini died in a car accident. One year later, on the anniversary of his death, his friends, who used to play with him in a band, decided to honor his memory by organizing a concert party. On that occasion Massimo’s friends dedicated to him a song titled “Beyond the limit” and one of them took about seventy pictures, but several times the camera jammed inexplicably.

When the rolls were processed, among all the pictures there was one that contained inexplicable gaudy colors and luminous streaks that drew his mother’s attention. In the picture she and a few friends were greatly surprised to find, in the middle, a blurred and semitransparent image bearing human features in which was immediately recognized Massimo’s likeness holding in his hand something that seemed to be a microphone.

Photograph in which the face center-top is an “extra.”

In 1999 Daniele Gullà carried out spectro-chromatographic and densitometric measurements on the picture, which ruled out any accidental or intentional counterfeiting of any nature. Then an anthropometric investigation was also performed by analyzing the face displayed in that picture and comparing it to Massimo’s image while alive. The measurements taken, based on the distance rates for the two faces compared on twelve anthropometric points, together with circumstantial evidence suggested that the paranormal face might belong to Massimo.

Two years later Daniele Gullà had acquired much more advanced technology, which is also used by the police in the United States, and obtained confirmation that the two images belong to the same person. For the Castagnini case, Daniele Gullà employed the Face Recognition and FaceIt software packages.

The alleged paranormal image was compared with an image dataset made up by 2,048 faces, including the one of Massimo Castagnini, which had been added to the database.

The choice made by the Eigenfaces function identified the file named “casta01A”, which is a picture of the living Massimo’s face, as the most similar to the paranormal image, with a degree of similarity of about 97.5 %. The result is remarkable in that the alleged anomalous image is lower in quality than an ordinary image; therefore, the number of required biometrical features is lower than the number one would hope for.

Comparison between the “extra” in the preceding. photograph and the person it is thought to be.

In summer 2004, after the acquisition of new software, it was possible for Daniele Gullà to repeat the identification test on Massimo’s paranormal face using the FBI Image Searching® software. That software, already used in Edna’s case, has a capability of reaching an accuracy rate above 99% based upon a database of 40,000 images. The recognition of Massimo Castagnini’s face was successfully accomplished with an identification rate of 99% after more than 1,900,000 cross-tests performed using the One-to-Many function.

Today, thanks to new software, we are able to reconstruct faces starting from the elements contained in the paranormal images and/or make comparisons by laying a reconstructed face on its alleged paranormal image.

How to conclude and explain the results?

The results of the analyses performed to date must be considered as an explorative sample of almost recurrent anomalies detectable in the electroacoustical structure of paranormal voices and of the possibilities of investigating paranormal images. Since the anomalies discovered seem to be of a similar type, it could be stated in a provisional way, that the paranormal voices are characterized by some substantial differences when compared to human voices. From my point of view such differences mainly refer to the process by which they are structured.

The subjective auditory and instrumental tests prove that the acoustic quality of the paranormal voices is the main variable in this phenomenon. In more than three decades covered by my personal survey, the variability was mainly found in the microphone voices where the range of audibility goes from whispered voices to extremely comprehensible voiced sounds. In the telephone voices, like Edna’s voice, the quality changes as well.

In many cases, those voices seem to have originated in the same manner as microphone voices, that is, by modulating the background noise or other sound material available at the moment. In other cases, such as those reported by D. Scott Rogo, the quality of the telephone voices seems to be almost the same as a normal telephone voice. This variability in the microphone and telephone voices was found in the Direct Radio Voices as well. For example, the Direct Radio Voices obtained by Friedrich Jürgenson and many other operators differ substantially, from the acoustical point of view, from those received by Marcello Bacci. Why?

In addition, sometimes the EVP operator’s own voice was recorded on the tape. Both Carlo Trajna, an engineer and well-known Italian researcher, and myself experienced this occurrence. In other instances, direct voices (not radio voices) were heard over the external speaker of the tape recorder while listening to a tape that contained pre-recorded normal acoustic material. A subsequent check revealed that such voices were not recorded on the tape.

In my opinion, the process by which paranormal voices are received may depend upon the degree of sensitiveness or mediumship existing in the operator. Basically, the presence in the operator of a deeply internalized conceptual model, together with expectations consistent with such a model, may be able to activate or create a hidden psychic channel for receiving voices in such a way. This occurrence happens, for example, when an EVP operator believes that the voices may be received through a radio in the same way as normal radio transmissions.

But how can the above mentioned psychic sensitivity or mediumship be rationally conceptualized? To begin, I believe that it is an attribute that everybody possesses to greater or lesser extent; also, it seems that the attribute of mediumship can be developed when a motivated operator devotes himself to experimenting on a regular basis. Secondly, this attribute seems to be supported by the deep inner conviction about the possibility of real communication with other planes of consciousness.

As early as 1985, I defined this particular psychological condition as “Inner Attentive Disposition.” Consciousness contemplates no more profound or perplexing question than this: what is the role of consciousness in the establishment of reality?

In the paradigm of our western culture, the human mind is limited to being a passive processor of sensorial experiences. Conversely, based upon the mystical traditions of oriental cultures, all experience in the physical world is presumed to be created by consciousness such that all tangible reality stems from illusion.

The empirical evidence of paranormal voices and images teaches us that the physical and psychological relationships between consciousness and the physical world entail subtle effects and processes that often appear to violate the most fundamental and consolidated scientific paradigms of space, time and causality. To this purpose I mention the conclusion of the great Danish physicist Niels Bohr about the enigma of modern quantum physics that I consider from many perspectives to be quite relevant to our research: “We are both onlookers and actors in the great drama of existence3

The recent experimental data acquired using state-of-the-art recording and data processing equipment, together with appropriate research protocols and updated interpretation techniques, led us toward a bio-psycho-cybernetical interpretation of the phenomenon. In other words, the final effects entail complex interactions within what I like to define as a Minds System, the definition of which provides for the possible existence of and the effective participation between one or more interfaced minds (incarnate and discarnate) that are able to communicate with each other thanks to the effective and functional psychic model acting in the operators’ minds.

These psychic models are able to produce effects on the physical plane through a kind of action, defined in the parapsychological literature as Psychokinetic effect or PK effect. In this regard I agree completely with the great English parapsychologist John Beloff4 when he said that psychokinesis couldn’t be a force, or energy, or a physical process. He believed that PK was an unexpected action resulting from a direct interconnection between our mind and the Universe with all that it contains.

John Beloff argued that the unexpected action could not result from a super-energy located in the human mind or body, but that it could be something that happens under certain circumstances. In other words, it could be an idea or a mental intention that is able to automatically force a physical system to express that idea or that intention. The occurrence should in itself be a conclusive event and self-explanatory without the need for any other process acting as the bridge to make the final results understandable.

It is evident that different operators obtain paranormal voices that have different acoustic characteristics even if they are experimenting using the same method and device. From my point of view, this could be the result of a different psychic model operating in the mind of each operator, at the conscious or unconscious level. It is probable that different psychic situations produce different physical effects depending upon the psychic model and how it is conceived and internalized by the operator.

I would like to conclude this presentation with a purely speculative reflection based upon from my personal experiences in searching for the dynamics that govern the psychic processes and what I imagine might exist behind what we observe and measure in our investigations.

I believe that in the immediate post-mortem state the surviving nucleus of consciousness does not suddenly become, as many people incorrectly assume, omniscient (i.e., knowing everything about the past, present and future).

I believe that after death, human consciousness continues to act, for a certain period of time, based upon the individual’s knowledge of the psychic models acquired while living.

The new state of existence could imply a more effective level of consciousness, like a more enlarged perception of reality. This situation may differ from individual to individual, depending upon the individual’s adaptation to his or her new state of consciousness. The dynamics for creating new psychic models involves both the consciousness of the living and discarnate.

In ITC, there is often mention of technical means or problems and other references typical of humans living on Earth. This situation suggests the persistence, in the surviving consciousness, of psychic models that were acquired while living in the physical world. This is, I believe, the reason that the vast majority of authentic transcommunication come from personalities who have passed over fairly recently. In such cases of surviving consciousness located “nearby” in the more immediate post-mortem plane, the discarnate being is still influenced by experiences on the physical plane and has therefore the same, or a quite similar, psychic model.

To structure a new psychic model, it is necessary to have a strong willingness to supersede all previous existing schemes with new ones, even if at first sight, they appear impossible. In other words, to reach the desired goal, it is necessary to have an attitude of faith strong enough to set aside any rational interference.

Jesus Christ preached the same concept when He spoke of “the faith that moves mountains”.

Thank you very much for your kind attention.

Hans Otto König Experiment

In the year 1974, Hans Otto König, now 66, a professional electroacoustics technician living in Mönchengladbach, by chance found himself listening to a discussion broadcast by ZdF (the second German TV Channel) in which Friedrich Jürgenson from Sweden, the pioneer of EVP, tried in vain to convince the well-known German parapsychologist Prof. Hans Bender and other critical scientists and journalists of the reality of extraordinary voices captured on his audio-tapes and apparently originating from the deceased.

Hans Otto König

König’s interest was aroused, and he resolved to start his own experiments in an attempt to demonstrate that the anomalous voices came from the unconscious of the experimenter rather than from the deceased. Instead, he received the singing voice of his late mother who addressed him and his father by name and asked whether or not they could hear her. During the following weeks, König was forced to the conclusion that the voices did indeed come from the so-called dead. He started his EVP experimentation using as background support noise a radio station transmitting in a foreign language, and although he obtained his positive results almost immediately, initially they were of very poor quality, consisting mostly of whispers and sighs rather than vocalizations.

Subsequently he changed his background noise from foreign language broadcasts to ultra-sounds, since this is an area of acoustics which he understands, and has used his professional expertise and psychic faculties to improve the quantity and quality of the contacts with the beyond—now known as Instrumental TransCommunication or ITC—by inventing and continuously modifying electronic devices specially developed for the purpose. Initially, he applied combined frequency-modulated mechanical ultrasonics transmitted and received by transducers in his laboratory. He then found that electromagnetic oscillations in the frequency range around 50 kHz produced the same results. Later he added a multifrequency infrared transmitter-receiver system, which demodulates infrared and modulates it again to a UHF vibration-oscillation from 10 m down to a 1 m wavelength, with a frequency of 30 MHz to 300 MHz. Currently he is working with a complex device based on quartz-crystals irradiated with ultraviolet light which he calls HRS (Hyper-Raum-System or Hyperspace System).

König tells us that he builds his various IC devices according to his own thoughts and the information he receives in dreams from the communicators. He further tells us that he goes into deep meditation for thirty minutes every day and while doing so can “see” (as a kind of psychic perception) his communicators as diffuse physical shapes, and that he has also been successful in photographing them using the Klaus Schreiber closed loop method. His explanation for the success of his experimentation is the key word “resonance,” which he says includes electromagnetic resonance.

The voices that now come through his loudspeaker are of a different, often excellent, quality, and he is sometimes able to dialogue with them. The contents of communications and the nature of the communicators themselves vary dependent upon the context. Deceased humans may answer the requests of their bereaved relatives and friends for comfort, while at other times, technical advice is given to König, and nameless cosmic entities, apparently outside our space-time, provide philosophical observations. The outcome of an experiment is never predictable, and may produce no results at all depending on mental-spiritual and other (unknown) conditions. König feels that audio results seem to improve in the presence of a harmonious audience, and the same is true for his work on transimages, which in one instance have already been obtained accompanied by the voice of the deceased person, whose identity was later discovered “by chance.”

The Two Experiments

The two experiments that are the subject of this Report were held respectively on September 10th and 11th, 2005, in two afternoon sessions held in a room at the Hotel Kaiserhof, in the German town of Wesel. Dr. Anabela Cardoso attended, accompanied in the unavoidable absence of Professor David Fontana by Mr. Carlos Fernández, the Technical Editor of the ITC Journal and an electronics technician with long experience of ITC data. Also accompanying Dr. Cardoso was Professor Ernst Senkowski, one of the foremost experts on ITC, who has known König well for many years, and who was responsible for helping to arrange Dr. Cardoso’s visit. The others present included visitors from Finland and some sixty of the regular observers of König’s previous experiments, together with a few individuals who were attending for the first time. König completely eschews publicity and avoids working with journalists and the media because of the negative experiences he has had with such groups in the past. All the communications were in German, which is the native language of König and of Professor Senkowski and in which Dr. Cardoso has some facility.

First Experiment, September 10th 2005.

König opened proceedings with an introductory talk that included recordings of voices received during earlier experiments. After a short meditation he then activated one of the older systems developed by him many years ago, which has misleadingly been called a “generator” but which in fact should be considered as a device open to the influx of information from hidden ranges of consciousness. This infrared/ultrasound device operates in a frequency range from 30 kHz to 70 kHz. The device, which looks like a rectangular metallic box, was built by König himself and the frequencies are mixed in its interior while an aerial placed on top of the generator transmits the signal to a receiver in the same band. An amplifier is connected to a mixing table and to the loudspeakers. König’s microphone and recording apparatus are also connected to the mixing table. When the voices started, silence was suddenly transformed into a beat, and the voices seemed to speak much above the beat. The communications that resulted lasted some two minutes and consisted of a nearly continuous dialogue between König and several voices.

The communications began with the habitual opening words. “Contact field closed” (i.e. closed to intruding entities), and finished with, “Contact end.” In all, there were fifteen exchanges. In Exchange Number 2, the “answer” did not directly refer to the question asked by König. In Number 5, the voice asked for a technical modification of the equipment being used. In Numbers 9 and 14 respectively, two names of earlier acquaintances of König, “Hubert” and “Helmut,” were given, the latter communicator spontaneously referring to König’s sick wife, Margaret.

Most of the voices were clear and could be heard above the permanent noise level from the equipment. In consequence the comprehensibility level was around eighty-five to ninety per cent for all those present during live listening, and one hundred per cent on replay. The voices were of excellent quality, but somehow did not possess the same degree of what Dr. Cardoso describes as the “inner clarity of an angelical prototype” that in her view was overpowering in the voices that came through during the experiment of the following day. Professor Senkowski expressed himself unable to always decide whether a voice sounded more male or more female.

An interesting observation concerns the varying speed of the utterances. For example, Exchange Number 12 was spoken very quickly, and here and in other cases, one had the impression that when the contact is nearing its end because of shortness of “energy,” the speech is accelerated. Another observation concerns the time lapse between the questions of the experimenter and the responses from the communicators. These lapses were generally in the range of a few seconds, but in Number 12, the voice broke in before König had completed his question, so that the two voices momentarily overlapped.

To some extent, the speech of the communicators possessed its own character and style, both of which are difficult to describe. Often the speech sounded not “normal” or not “human-like.” Grammar was not always correct. The contents sometimes were metaphorical and not easily interpreted, especially when the speaker seemed to be a “remote,” non-human being. An example is Number 2, when subsequent to König asking who and where the “speaker” is, the answer, “Ultraschall ist das Bild” is given, (translated as, “Ultrasonics is the image”). This answer could be understood as meaning that the voice, as mediated by the electromagnetic oscillations in the range of 30 to 70 kHz, is an “image” of the speaker, who remains unnamed. Alternatively the speaker may be identifying his (mental) “position,” as in or near the equipment being used. But these alternatives must remain more or less speculative.

Second Experiment, September 11th 2005

This experiment was carried out with the HRS system that consists of a large quartz-crystal and ten smaller ones, all of them irradiated by ultraviolet light of different wavelengths. As in the first experiment, we started with a short meditation, after which the device was switched on. After some fifteen minutes, the first voice came through, and a dialogue developed with nineteen exchanges taking place lasting seven minutes and fifty-three seconds.

The background noise, according to König, actually produced from the “other side,” was quite different from that heard from the so-called generator in Experiment One. It consisted of a nearly periodic bird-like high-pitched twittering or chirping, mixed with slow roaring like a storm and waves on a seashore. Most voices were absolutely clear and immediately understood, provided they were not too fast. König spoke his questions in a meditative state, speaking slowly, and the voices answered in their chosen manner.

Most responses were given immediately, although a few were delayed up to twelve seconds, Most of the voices seemed to come from one single entity, who sounded to be female, and they possessed a special modulation, similar to singing. Most of them sounded rather “neutral” or “detached” with the possible exception of Exchange Number 10, where the voice seemed to express some underlying contempt for the stupidity of Christian beliefs, describing them as “unreasonable superstition.” In Number 8 were the words, “I stem from the realm of stars,” delivered in an elevated poetic style. The German words used by the entity, “lch stamme,” can be translated simply as, “I come,” or more tellingly as, I am descended.”

The dialogue seemed to be presided over by a highly intelligent source that treated adult humans like children, with some compassion or even regret. For example Number 15, when we were told that, “But it is probably too difficult for you to comprehend this.” (“This” being their magnificent, super-terrestrial world). However, one should take into consideration the difficulties pertaining to the adaptation process of the different structures of human and the entities’ consciousness in contact through these communications. In the rather long pause between Number 18 and the end of the contact, dull beats similar to drumming appeared as additional signals, although their meaning remained unclear. The live comprehensibility level was around one hundred per cent for all those present.

The transcripts of the communications received during the above mentioned experiments and the respective translations provide by Dr. Ernst Senkowski are available below

During the two days spent in Wesel, Dr. Cardoso had the opportunity to exchange views with Hans-Otto König on a number of issues—namely on the content of the communications she receives from the group of communicators calling themselves Rio do Tempo (Timestream) and recorded by Dr. Cardoso, and of the communications received by Hans-Otto König. Among the many interesting similarities there is, for instance, the fact that König’s communicators very rarely speak in the singular and almost always in the plural, referring to themselves as “We,” just as do the communicators from Rio do Tempo.

They also speak of “meditating (in their world),” as do the voices from Rio do Tempo. Furthermore, König’s and Rio do Tempo communicators tell us that, in the third level of the next world, deceased animals and deceased humans are together again, and that at this level, communication with animals and plants is also possible. Another aspect of the similarities regards the interchange of energies between the communicators and the experimenters. Hans Otto König said on September 10, 2005, prior to the experiment of that day, that the entities who speak with him “can as well charge, or even overcharge, him before a contact, and at other times he feels devoid of energy after a contact.”

From her side on September 2, 2005, Dr. Cardoso wrote in her contacts log the following: “… when I am in the studio I seem to lose track of time. I wouldn’t know if I have been in for fifteen minutes or for over one hour. Also, those days when I feel particularly energetic, and upon request of the communicators, stay inside for a period of time, I feel emptied out and tired when I go out of the studio. On the other hand, the days when I feel very tired and go into the studio, upon going out I feel recovered and the tiredness has disappeared. It is as if there is an interchange of energies with the communicators.” As with the communicators from Rio do Tempo, who refer to themselves as speaking from a “station,” König’s communicators say the group who organizes their contacts is known as “ZentraIe.”


Our conclusion is that we witnessed two fascinating experiments that are the outcome of thirty years of engaged and devoted work by Hans-Otto König, who works without support and who has often been fiercely attacked by what Professor Senkowski calls envious or even ill-intentioned people. Hopefully, at some point in the future, Hans Otto König will be considered one of the most prominent pioneers of ITC, and his wish to prove the reality of life after death will perhaps be fulfilled by a less materialistic science. Meanwhile, we remain thankful for the opportunity to observe the work of this man, and wish him the continuation of success in the laborious developmental path that he has chosen to follow.
