An audio sample recorded at the Thunderbird Lodge on the east shore of Lake Tahoe by the AA-EVP, who believe it is an example of EVP. |
Electronic voice phenomena (EVP) is a term coined by publishing company Colin Smythe Ltd. to describe speech or speech-like sounds they felt were of paranormal origin occurring on previously unused recording media. It was first claimed by Raymond Bayless, and previously called "Raudive voices" by Konstantin Raudive. Most examples put forward as EVP are brief, usually lasting the length of a word or short phrase, though longer segments are not unheard of.
According to Alexander MacRae, a member of the AA-EVP, and retired journalist (and former AA-EVP member) Judith Chisholm, EVP is caused by psychokinesis or the voices of spirits. Scientists, however, say EVP can be explained by such things as pareidolia or radio interference.
History
EVP was not named or defined until the mid 20th century, although it is reported to have been observed in various forms since early in the century.
Von Szalay, Bayless, and Jürgenson
The self-proclaimed medium Attila von Szalay (Sealay) was among the the first people to claim he taperecorded voices of the dead. He tried various techniques during the 1930s, before joining with Raymond Bayless in the 1950s. Together, they began by experimenting using a 78 RPM Pack Bell record cutter. When the results failed to meet their expectations, Bayless constructed a custom made recording rig consisting of a soundproofed clothes closet featuring a microphone inside a tinfoil covered trumpet that lead to a remote tape recorder and speaker system in order to to allow the sounds inside the closet to be monitored and recorded.
At times the recording closet was empty, while at other times it was occupied by a volunteer. Using this setup, Szalay and Bayless report having captured many voices on tape that were not not heard through the speaker when the closet was occupied. Records of their experiment were later published in the Journal of the American Society for Psychical Research.
EVP attracted further interest when, in 1959, Swedish film producer Friedrich Jürgenson captured what he believed to be the discarnate voice of a Norwegian speaking man on a recording of bird songs that he had made. Jürgenson went on to make many tape recordings, including one in which he believed he received a message from his late mother. Jürgenson's recordings attracted the attention of German parapsychologist Hans Bender, the head of a research team at the Institute for Border Areas of Psychology and Mental Health (University of Freiburg). After analyzing them, Bender concluded that Jürgenson's tapes were "susceptible to a paranormal interpretation."
Raudive
Jürgenson's experiments were also followed up by Latvian psychologist Konstantin Raudive. Raudive worked in conjunction with both Jürgenson and Bender and became heavily involved in EVP research, conducting over 100,000 recordings under various conditions.
After various experiments, Raudive devised three primary methods for conducting EVP research; allowing a tape to record in a silent room, recording the static from an un-tuned radio, and recording the static of an un-tuned diode receiver. He also reported that there were four key characteristics that differentiated the voices captured on tape from normal speech:
- Voices used a different rhythm to regular speech
- Voices used a stunted "telegram-style" sentences
- Voices did not obey standard grammatical rules
- Recordings may consist of multiple languages
Raudive's recordings were sometimes criticized for not following a pattern consistent with intelligent communication (for example, consisting of an answer that was unrelated to a question posed by Raudive) or because they appear to be random collections of words with no overall meaning. Raudive's interpretations of his tapes were also criticized for being highly subjective in nature.
In 1971 Raudive conducted a controlled experiment in a shielded laboratory that was designed to block out both sound and potential interference from external sources such as television and radio signals. Raudive recorded his own voice for 18 minutes and no other sounds were made or heard. When the recordings were played back, observers are said to have found that 200 other voices were present on the tape.
Spiricom
In 1980, American medium William O'Neil constructed a device known as "The Spiricom," which he claimed was based on instructions given to him by the spirit of deceased Cornell physicist George J. Mueller. The device consisted of thirteen audio oscillators, each tuned to an audio frequency between 131Hz and 701Hz (the approximate tone range for an adult male voice), which were fed to the input of an FM radio transmitter tuned to 29.57 Mhz. The resulting broadcast was picked up by a nearby radio receiver, also tuned to 29.57 Mhz FM. Through this device, O'Neil claimed that he was able to hold two-way conversations with the spirits of the dead, some of which he recorded and made available to researchers.
The results of O'Neil's experiments were announced at a Washington, DC, press conference on the April 6, 1982, by retired industrialist George Meek, who had been associated with O'Neil since the early 1970s.
Meek and O'Neil went on to found the Metascience Foundation of North Carolina (Metascience Foundation Inc), and to provide the design specifications for Spiricom to researchers for free. However, nobody is known to have ever been able to replicate O'Neil's results using their own Spiricom devices.
In response to the failure of other Spiricom systems, Meek later concluded that O'Neil, a self professed medium, formed a key component of the device. Meek went on to state that he knew of no system for communicating with the dead having achieved success unless at least one member of the team investigating it had psychic abilities.
AA-EVP
In 1982, Sarah Estep founded the American Association of Electronic Voice Phenomena in Severna Park, Maryland, with the purpose of increasing awareness of EVP and teaching standardized methods for capturing it. Estep began her exploration of EVP in 1976, and claims to have made hundreds of recordings of messages from deceased friends, relatives, and other individuals, including Konstantin Raudive, Beethoven, a lamplighter from 18th century Philadelphia, PA, and extraterrestrials whom she speculated originated from other planets or dimensions. Today, the AA-EVP is a nonprofit educational association headed by Directors Tom and Lisa Butler, dedicated to the support of people who are interested in or studying EVP and Instrumental transcommunication. The organization lists members in twenty countries and maintains a web site that offers examples, techniques and concepts concerning EVP.
Baruss
In 1997, researchers with the Department of Psychology at the University of Western Ontario conducted several EVP experiments using Raudive's methods and the work of Instrumental Transcommunication (ITC) researcher Mark Macy as a guide.
During 81 sessions, researchers recorded a total of 60 hours and 11 minutes of data in the presence of a neutral volunteer who either sat in silence or attempted to make verbal contact with potential sources of EVP. Over the course of the experiment researchers recorded several non-speech audio events similar to those which some paranormal researchers have previously associated with EVP, but which fell outside the parameters of the experiment because they did not represent a form of communication. Several events which could be interpreted as voices "with a little imagination" were recorded, but were deemed to be too few, too random, and too open to interpretation to be usable.
The experiment was deemed to have failed to capture EVP, and to have provided no evidence validating the phenomena. Their findings were published in the Journal of Scientific Exploration in 2001 by Imants Baruss.
MacRae
In March 2003, Scottish researcher Alexander MacRae made a number of attempts to capture EVP in a specially designed laboratory belonging to the Institute of Noetic Science in Petaluma, California. The laboratory was described as being "double-screened"; it was shielded against electromagnetic radiation to prevent interference from radio transmissions or near by electronic devices and insulated against sound to prevent contamination of recordings by external noise sources.
Over the course of the experiment, MacRae reported capturing a number of anomalies which were subsequently isolated and analyzed. Based on this analysis, and the level of screening against outside interference, MacRae concluded that the anomalies represented distinct speech from a source that could not be explained through conventional means.
Details of MacRae's experiments, methods, and conclusions were published in the October 2005 issue of the Journal of the Society for Psychical Research.
Proposed explanations
Paranormal
There is no consensus within the paranormal community as to the origins of EVP or how best to capture it; however, a number of different explanations have been put forward.
- Discarnate entities: EVP is the voices of discarnate entities who communicate with the living through electronic devices. Some proponents allege the sounds cannot be heard by the human ear because spirits do not have vocal chords, and instead imprint their voices on the recording media by some unknown method.
- Extraterrestrial entities: EVP represents contact with "nature energies" or extraterrestrials. There is also speculation that the beings may originate from an alternate dimension and the communications are the result of some unknown fluctuation in space and time.
- Psychokinesis: EVP is created by the researcher's subconscious "mind-over-matter" ability to influence matter or energy without the use of any currently known type of physical means. Some experimenters say they have received messages from a sleeping colleague and feel this may indicate that living humans are capable of creating EVP, a phenomenon which they speculate accounts for some percentage of recordings.
Scientific
As with all paranormal phenomena, the origins and existence of EVP are disputed, and a variety of alternative explanations have been put forward for the phenomena.
- Interference: Certain instances of EVP, especially those recorded on devices which contain RLC circuittry, represent radio signals of voices/sounds from broadcast sources. Interference from CB Radio transmissions and wireless baby minders, or anomalies generated though cross modulation from other electronic devices, are all documented phenomena. It is even possible for circuits to resonate without any external power source by means of radio reception.
- Auditory pareidolia: Auditory pareidolia, a condition created when the brain incorrectly interprets random patterns as being familiar patterns. In this case, it results in an observer interpreting random noise on an audio recording as being the familiar sound of a human voice. The propensity for EVP to be in a language understood well by those researching it, rather than in an unfamiliar language, has been cited as evidence of this.
- Capture errors: Anomalies created by the method used to capture EVP, such as noise generated through the over-amplification of a signal at the point of recording, is known to cause a variety of aberrations.
- Processing artifacts: Artifacts created during attempts to boost the clarity of an existing recording through methods such as re-sampling, frequency isolation, and noise reduction/enhancement, until they take on qualities significantly different from those that were present in the original recording.
- Hoaxes: A percentage of EVP may be hoaxes created by frauds or pranksters.
Status of EVP
EVP has been, for the most part, ignored by the scientific community. Few parapsychologists have studied it, and little literature can be found on it in physical science peer-reviewed journals in the English language. Experiments performed by scientists have found no evidence of EVP. Other experiments recorded anomalies which, upon analysis and listening tests, were interpreted to " have been in some way paranormal." At this point, no evidence of EVP has been subjected to scientific scrutiny and peer review, and the concept has little or no support in the scientific community
Trivia
In the 1920s, the American inventor Thomas Edison told a reporter with Scientific American that he was working on a machine that could contact the dead, and the story was printed in many newspapers. However, Edison announced a few years later that he had been making a joke at the reporter's expense, and that he had not been working on such a device.
EVP in fiction
- The main character's mother Pattern Recognition by William Gibson tries to convince her that her father is communicating with her from recordings after his death/disappearance in the September 11, 2001 attacks.
- Do Det Ike by Gerry Connelly, a science fiction story published in Dream magazine in 1989, has EVP used as a means of interstellar communication.
- Legion by William Peter Blatty, the 1983 'sequel' to his 1971 novel The Exorcist, contains a subplot where Dr. Vincent Amfortas, a terminally-ill neurologist, leaves a "to-be-opened-upon-my-death" letter for Lt. Kinderman detailing his accounts of contact with the dead (including Amfortas' recently deceased wife, Ann) through EVP recordings. The book Breakthrough by Konstantin Raudive is mentioned in the novel, although Amfortas' character and the EVP subplot do not appear in the film version of the novel, Exorcist III.
- In episode 9 of Ghost Whisperer's first season, a dead woman tries to reach her son using EVP.
- The Electronic Ghosts (ISBN 1846853958) is a book about an electronic engineer who becomes involved with EVP, eventually using a diode and radio frequency machine to contact a sinister entity.
- EVP is a common plot device in the TV series Supernatural, which takes from many legends and paranormal phenomenon.
- In the The Sixth Sense, starring Bruce Willis, Willis' character realizes that audiotapes of his past patient interviews include the voices of dead people, who have been haunting said patient.
- White Noise, a 2005 movie starring Michael Keaton, focuses exclusively on the phenomenon of EVP and the main character's attempts to contact his recently deceased wife through it. In doing so, he draws the wrath of three sinister figures (possibly meant to personify shadow people). The filmmakers assert at the end of the film that 1 in 12 EVP messages received is threatening in nature, a figure disputed by many in the field.
- Giving Up the Ghost: The Walk-In is a real-life novel threading together paranormal events, research on the walk-in phenomenon, and EVP recorded by the author, a member of the AA-EVP.
- White Noise 2: The Light is an indirect sequel to White Noise starring Nathan Fillion. The protagonist's wife and child are killed in a seemingly random shooting, leading him to attempt to take his own life by overdosing. His heart stops and he is revived by high voltage defibrillation. After recovering, he seems to be suffering side effects, including generating electrical interference and being able to see white auras on certain people. He soon learns that he sees the auras on people that are about to die. He decides to use this ability to save lives, but soon learns that his actions have deeper and more sinister consequences.
