Within ghost hunting and parapsychology, electronic voice phenomena (EVP) are sounds found on electronic recordings that are interpreted as spirit voices that have been either unintentionally recorded or intentionally requested and recorded. Parapsychologist Konstantīns Raudive, who popularized the idea in the 1970s, described EVP as typically brief, usually the length of a word or short phrase.
Enthusiasts consider EVP to be a form of paranormal phenomenon often found in recordings with static or other background noise. However, scientists regard EVP as a form of auditory pareidolia (interpreting random sounds as voices in one's own language) and a pseudoscience promulgated by popular culture. Prosaic explanations for EVP include apophenia (perceiving patterns in random information), equipment artifacts, and hoaxes.
As the Spiritualist religious movement became prominent in the 1840s–1920s with a distinguishing belief that the spirits of the dead can be contacted by mediums, new technologies of the era including photography were employed by spiritualists in an effort to demonstrate contact with a spirit world. So popular were such ideas that Thomas Edison was asked in an interview with Scientific American to comment on the possibility of using his inventions to communicate with spirits. He replied that if the spirits were only capable of subtle influences, a sensitive recording device would provide a better chance of spirit communication than the table tipping and ouija boards mediums employed at the time. However, there is no indication that Edison ever designed or constructed a device for such a purpose. As sound recording became widespread, mediums explored using this technology to demonstrate communication with the dead as well. Spiritualism declined in the latter part of the 20th century, but attempts to use portable recording devices and modern digital technologies to communicate with spirits continued.:352–381
American photographer Attila von Szalay was among the first to try recording what he believed to be voices of the dead as a way to augment his investigations in photographing ghosts. He began his attempts in 1941 using a 78 rpm record, but it wasn't until 1956 — after switching to a reel-to-reel tape recorder — that he believed he was successful. Working with Raymond Bayless, von Szalay conducted a number of recording sessions with a custom-made apparatus, consisting of a microphone in an insulated cabinet connected to an external recording device and speaker. Szalay reported finding many sounds on the tape that could not be heard on the speaker at the time of recording, some of which were recorded when there was no one in the cabinet. He believed these sounds to be the voices of discarnate spirits. Among the first recordings believed to be spirit voices were such messages as "This is G!", "Hot dog, Art!", and "Merry Christmas and Happy New Year to you all". Von Szalay and Raymond Bayless' work was published by the Journal of the American Society for Psychical Research in 1959. Bayless later went on to co-author the 1979 book, Phone Calls From the Dead.
In 1959, Swedish painter and film producer Friedrich Jürgenson was recording bird songs. Upon playing the tape later, he heard what he interpreted to be his dead father's voice and then the spirit of his deceased wife calling his name. He went on to make several more recordings, including one that he said contained a message from his late mother.
Konstantin Raudive, a Latvian psychologist who had taught at the Uppsala University, Sweden and who had worked in conjunction with Jürgenson, made over 100,000 recordings which he described as being communications with discarnate people. Some of these recordings were conducted in an RF-screened laboratory and contained words Raudive said were identifiable.:352–381 In an attempt to confirm the content of his collection of recordings, Raudive invited listeners to hear and interpret them.:353, 496 He believed that the clarity of the voices heard in his recordings implied that they could not be readily explained by normal means.:352–381 Raudive published his first book, Breakthrough: An Amazing Experiment in Electronic Communication with the Dead in 1968 and it was translated into English in 1971.
In 1980, William O'Neil constructed an electronic audio device called "The Spiricom". O'Neil claimed the device was built to specifications which he received psychically from George Mueller, a scientist who had died six years previously.:352–381 At a Washington, DC press conference on April 6, 1982, O'Neil stated that he was able to hold two-way conversations with spirits through the Spiricom device, and provided the design specifications to researchers for free. However, nobody is known to have replicated the results O'Neil claimed using his own Spiricom devices. O'Neil's partner, retired industrialist George Meek, attributed O'Neil's success, and the inability of others to replicate it, to O'Neil's mediumistic abilities forming part of the loop that made the system work.
Another electronic device specifically constructed in an attempt to capture EVP is "Frank's Box" or the "Ghost Box", created in 2002 by EVP enthusiast Frank Sumption for supposed real-time communication with the dead. Sumption claims he received his design instructions from the spirit world. The device is described as a combination white noise generator and AM radio receiver modified to sweep back and forth through the AM band selecting split-second snippets of sound. Critics of the device say its effect is subjective and incapable of being replicated, and since it relies on radio noise, any meaningful response a user gets is purely coincidental, or simply the result of pareidolia. Paranormal researcher Ben Radford writes that Frank's Box is a "modern version of the Ouija board... also known as the 'broken radio'".
In 1982, Sarah Estep founded the American Association of Electronic Voice Phenomena (AA-EVP) in Severna Park, Maryland, a nonprofit organization with the purpose of increasing awareness of EVP, and of teaching standardized methods for capturing it. Estep began her exploration of EVP in 1976, and says she has made hundreds of recordings of messages from deceased friends, relatives, and extraterrestrials whom she speculated originated from other planets or dimensions.
The term Instrumental Trans-Communication (ITC) was coined by Ernst Senkowski in the 1970s to refer more generally to communication through any sort of electronic device such as tape recorders, fax machines, television sets or computers between spirits or other discarnate entities and the living. One particularly famous claimed incidence of ITC occurred when the image of EVP enthusiast Friedrich Jürgenson (whose funeral was held that day) was said to have appeared on a television in the home of a colleague, which had been purposefully tuned to a vacant channel. ITC enthusiasts also look at the TV and video camera feedback loop of the Droste effect.
In 1979, parapsychologist D. Scott Rogo described an alleged paranormal phenomenon in which people report that they receive simple, brief, and usually single-occurrence telephone calls from spirits of deceased relatives, friends, or strangers. Rosemary Guiley has written "within the parapsychology establishment, Rogo was often faulted for poor scholarship, which, critics said, led to erroneous conclusions."
In 1995, the parapsychologist David Fontana proposed in an article that poltergeists could haunt tape recorders. He speculated that this may have happened to the parapsychologist Maurice Grosse who investigated the Enfield Poltergeist case. However, Tom Flynn a media expert for the Committee for Skeptical Inquiry examined Fontana's article and suggested an entirely naturalistic explanation for the phenomena. According to the skeptical investigator Joe Nickell "Occasionally, especially with older tape and under humid conditions, as the tape travels it can adhere to one of the guide posts. When this happens on a deck where both supply and take-up spindles are powered, the tape continues to feed, creating a fold. It was such a loop of tape, Flynn theorizes, that threaded its way amid the works of Grosse's recorder."
In 1997, Imants Barušs, of the Department of Psychology at the University of Western Ontario, conducted a series of experiments using the methods of EVP investigator Konstantin Raudive, and the work of "instrumental transcommunication researcher" Mark Macy, as a guide. A radio was tuned to an empty frequency, and over 81 sessions a total of 60 hours and 11 minutes of recordings were collected. During recordings, a person either sat in silence or attempted to make verbal contact with potential sources of EVP. Barušs stated that he did record several events that sounded like voices, but they were too few and too random to represent viable data and too open to interpretation to be described definitively as EVP. He concluded: "While we did replicate EVP in the weak sense of finding voices on audio tapes, none of the phenomena found in our study was clearly anomalous, let alone attributable to discarnate beings. Hence we have failed to replicate EVP in the strong sense." The findings were published in the Journal of Scientific Exploration in 2001, and include a literature review.
In 2005, the Journal of the Society for Psychical Research published a report by paranormal investigator Alexander MacRae. MacRae conducted recording sessions using a device of his own design that generated EVP. In an attempt to demonstrate that different individuals would interpret EVP in the recordings the same way, MacRae asked seven people to compare some selections to a list of five phrases he provided, and to choose the best match. MacRae said the results of the listening panels indicated that the selections were of paranormal origin.
Portable digital voice recorders are currently the technology of choice for some EVP investigators. Since some of these devices are very susceptible to Radio Frequency (RF) contamination, EVP enthusiasts sometimes try to record EVP in RF- and sound-screened rooms.
Some EVP enthusiasts describe hearing the words in EVP as an ability, much like learning a new language. Skeptics suggest that the claimed instances may be misinterpretations of natural phenomena, inadvertent influence of the electronic equipment by researchers, or deliberate influencing of the researchers and the equipment by third parties. EVP and ITC are seldom researched within the scientific community, so most research in the field is carried out by amateur researchers who lack training and resources to conduct scientific research, and who are motivated by subjective notions.
Paranormal claims for the origin of EVP include living humans imprinting thoughts directly on an electronic medium through psychokinesis and communication by discarnate entities such as spirits, nature energies, beings from other dimensions, or extraterrestrials. Paranormal explanations for EVP generally assume production of EVP by a communicating intelligence through means other than the typical functioning of communication technologies. Natural explanations for reported instances of EVP tend to dispute this assumption explicitly and provide explanations which do not require novel mechanisms that are not based on recognized scientific phenomena.
One study, by psychologist Imants Barušs, was unable to replicate suggested paranormal origins for EVP recorded under controlled conditions. Brian Regal in Pseudoscience: A Critical Encyclopedia (2009) has written "A case can be made for the idea that many EVPs are artifacts of the recording process itself with which the operators are unfamiliar. The majority of EVPS have alternative, nonspiritual sources; anomalous ones have no clear proof they are of spiritual origin."
There are a number of simple scientific explanations that can account for why some listeners to the static on audio devices may believe they hear voices, including radio interference and the tendency of the human brain to recognize patterns in random stimuli. Some recordings may be hoaxes created by frauds or pranksters.
Auditory pareidolia is a situation created when the brain incorrectly interprets random patterns as being familiar patterns. In the case of EVP it could result in an observer interpreting random noise on an audio recording as being the familiar sound of a human voice. The propensity for an apparent voice heard in white noise recordings to be in a language understood well by those researching it, rather than in an unfamiliar language, has been cited as evidence of this, and a broad class of phenomena referred to by author Joe Banks as Rorschach Audio has been described as a global explanation for all manifestations of EVP.
Skeptics such as David Federlein, Chris French, Terence Hines and Michael Shermer say that EVP are usually recorded by raising the "noise floor" – the electrical noise created by all electrical devices – in order to create white noise. When this noise is filtered, it can be made to produce noises which sound like speech. Federlein says that this is no different from using a wah pedal on a guitar, which is a focused sweep filter which moves around the spectrum and creates open vowel sounds. This, according to Federlein, sounds exactly like some EVP. This, in combination with such things as cross modulation of radio stations or faulty ground loops can cause the impression of paranormal voices. The human brain evolved to recognize patterns, and if a person listens to enough noise the brain will detect words, even when there is no intelligent source for them. Expectation also plays an important part in making people believe they are hearing voices in random noise.
Apophenia is related to, but distinct from pareidolia. Apophenia is defined as "the spontaneous finding of connections or meaning in things which are random, unconnected or meaningless", and has been put forward as a possible explanation. According to the psychologist James Alcock what people hear in EVP recordings can best be explained by apophenia, cross-modulation or expectation and wishful thinking. Alcock concluded "Electronic Voice Phenomena are the products of hope and expectation; the claims wither away under the light of scientific scrutiny."
Interference, for example, is seen in certain EVP recordings, especially those recorded on devices which contain RLC circuitry. These cases represent radio signals of voices or other sounds from broadcast sources. Interference from CB Radio transmissions and wireless baby monitors, or anomalies generated through cross modulation from other electronic devices, are all documented phenomena. It is even possible for circuits to resonate without any internal power source by means of radio reception.
Artifacts created during attempts to boost the clarity of an existing recording might explain some EVP. Methods include re-sampling, frequency isolation, and noise reduction or enhancement, which can cause recordings to take on qualities significantly different from those that were present in the original recording.
The very first EVP recordings may have originated from the use of tape recording equipment with poorly aligned erasure and recording heads, resulting in the incomplete erasure of previous audio recordings on the tape. This could allow a small percentage of previous content to be superimposed or mixed into a new 'silent' recording.
For all radio transmissions above 30 MHz (which are not reflected by the ionosphere) there is a possibility of meteor reflection of the radio signal. Meteors leave a trail of ionised particles and electrons as they pass through the upper atmosphere (a process called ablation) which reflect transmission radio waves which would usually flow into space. These reflected waves are from transmitters which are below the horizon of the received meteor reflection. In Europe this means the brief scattered wave may carry a foreign voice which can interfere with radio receivers. Meteor reflected radio waves last between 0.05 seconds and 1 second, depending on the size of the meteor.
There are a number of organizations dedicated to studying EVP and instrumental transcommunication, or which otherwise express interest in the subject. Individuals within these organizations may participate in investigations, author books or journal articles, deliver presentations, and hold conferences where they share experiences. In addition organizations exist which dispute the validity of the phenomena on scientific grounds.
The Association TransCommunication (ATransC), formerly the American Association of Electronic Voice Phenomena (AA-EVP), and the International Ghost Hunters Society conduct ongoing investigations of EVP and ITC including collecting examples of purported EVP available over the internet. The Rorschach Audio Project, initiated by sound artist Joe Banks, which presents EVP as a product of radio interference combined with auditory pareidolia and the Interdisciplinary Laboratory for Biopsychocybernetics Research, a non-profit organization dedicated to studying anomalous phenomena related to neurophysiological conditions. According to the AA-EVP it is "the only organized group of researchers we know of specializing in the study of ITC".
Parapsychologists and Spiritualists have an ongoing interest in EVP. Many Spiritualists experiment with a variety of techniques for spirit communication which they believe provide evidence of the continuation of life. According to the National Spiritualist Association of Churches, "An important modern day development in mediumship is spirit communications via an electronic device. This is most commonly known as Electronic Voice Phenomena (EVP)". An informal survey by the organization's Department Of Phenomenal Evidence cites that 1/3 of churches conduct sessions in which participants seek to communicate with spirit entities using EVP.
The concept of EVP has influenced popular culture. It is popular as an entertaining pursuit, as in ghost hunting, and as a means of dealing with grief. It has influenced literature, radio, film, television, and music.
Investigation of EVP is the subject of hundreds of regional and national groups and Internet message boards. Paranormal investigator John Zaffis claims, "There's been a boom in ghost hunting ever since the Internet took off." Investigators, equipped with electronic gear—like EMF meters, video cameras, and audio recorders—scour reportedly haunted venues, trying to uncover visual and audio evidence of ghosts. Many use portable recording devices in an attempt to capture EVP.
Films involving EVP include Poltergeist, The Sixth Sense, and White Noise. It has also been featured on television series like Ghost Whisperer, The Omega Factor, A Haunting, Ghost Hunters, MonsterQuest, Ghost Adventures, The Secret Saturdays, Fact or Faked: Paranormal Files, Supernatural, Derren Brown Investigates, and Ghost Lab.
Legion, a 1983 novel by William Peter Blatty, contains a subplot where Dr. Vincent Amfortas, a terminally ill neurologist, leaves a "to-be-opened-upon-my-death" letter for Father Dyer detailing his accounts of contact with the dead, including the doctor's recently deceased wife, Ann, through EVP recordings. Amfortas' character and the EVP subplot do not appear in the film version of the novel, The Exorcist III, although in Kinderman's dream dead people are seen trying to communicate with the living by radio.
In Pattern Recognition, a 2003 novel by William Gibson, the main character's mother tries to convince her that her father is communicating with her from recordings after his death/disappearance in the September 11, 2001 attacks.'
In With the people from the bridge, a 2014 play by Dimitris Lyacos based on the idea of the return of the dead, the voice of the female character NCTV is transmitted from a television monitor amidst a static/white noise background.
During the outro to "Rubber Ring" by The Smiths, a sample from an EVP recording is repeated. The phrase "You are sleeping, you do not want to believe," is a 'translation' of the 'spirit voices' from a 1970s flexitape. The original recording is from the 1971 record which accompanied Raudive's book 'Breakthrough', and which was re-issued as a flexi-disc in the 1980s free with The Unexplained magazine.
The band Giles Corey, founded by Dan Barrett composed a song called 'Empty Churches' which features track 2 called 'Raymond Cass', track 36 called 'Justified Theft' and track 38 called 'Tramping' from the album An Introduction to EVP by The Ghost Orchid which features excerpts from different EVP experiments produced by many researchers, although most are unknown, some have been pointed out to be more known researchers who studied EVP recordings including Friedrich Jurgenson, Raymond Cass and Konstantin Raudive.
Annabelle is a fictional character in the The Conjuring Universe, an American horror film franchise. The character, a haunted doll, is based on accounts by paranormal investigators and authors Ed and Lorraine Warren. Annabelle first appeared in the 2013 film The Conjuring.Bilocation
Bilocation, or sometimes multilocation, is an alleged psychic or miraculous ability wherein an individual or object is located (or appears to be located) in two distinct places at the same time.The concept has been used in a wide range of historical and philosophical systems, ranging from early Greek philosophy to modern religious stories, occultism and magic.Carl Michael von Hausswolff
Carl Michael von Hausswolff (born 1956) is a composer, visual artist, and curator based in Stockholm, Sweden. His main tools are recording devices (camera, tape deck, radar, sonar) used in an ongoing investigation of electricity, frequency, architectural space, and paranormal electronic interference. Major exhibitions include Manifesta (1996), documenta X (1997), the Johannesburg Biennial (1997), Sound Art - Sound as Media at ICC in Tokyo (2000), the Venice Biennale (2001, 2003, and 2005), and Portikus, Frankfurt (2004). Von Hausswolff received a Prix Ars Electronica award for Digital Music in 2002.
Von Hausswolff was born in Linköping. He is an expert in the work of Friedrich Jürgenson, an electronic voice phenomenon (EVP) researcher who claimed to have detected voices of the dead hidden in radio static. Von Hausswolff's own sound works are pure, intuitive studies of electricity, frequency, and tone. Collaborators include Erik Pauser, with whom he worked as Phauss (1981-1993), Leif Elggren, and John Duncan (artist). He also collaborates with EVP researcher Michael Esposito, filmmaker Thomas Nordanstad, and with Graham Lewis (Wire) and Jean-Louis Huhta in the band OSCID.
Von Hausswolff is co-monarch (with Elggren) of the conceptual art project The Kingdoms of Elgaland-Vargaland (KREV): all areas of no-man's land, territories between national boundaries on both land and sea, and digital and mental spaces. This nation has its own national anthem, flag, coat of arms, currency, citizens, and ministers.
Recent audio works include "800 000 Seconds in Harar" (Touch), "Matter Transfer" (iDeal), "The Wonderful World of Male Intuition" (Oral), "There Are No Crows Flying Around the Hancock Building" (Lampo), "Rats", "Maggots", and "Bugs" (all three on Laton), "Three Overpopulated Cities ..." (Sub Rosa), "A Lecture on Disturbances in Architecture" (Firework Editions), and "Ström" and "Leech" (both on Raster-Noton).
Other visual works include "Red Pool" (Cities on the Move, Bangkok, 1999), "Red Night" (SITE Santa Fe, 1999), "Red Code" (CCA Kitakyushu, 2001), "Red Empty" (Lampo/WhiteWalls, Chicago, 2003), and "Red Mersey" (Liverpool Biennial, 2004).
He is also the curator and producer of the sound-installation "freq out", shown at Moderna Museet (Stockholm), Henie-Onstad Center (Oslo), Sonambiente (Berlin), and other places.
Around the year 1986, he formed the Swedish independent label Radium 226.05 and in 1990 he formed the label Anckarström.
In 2012, Von Hausswolff was heavily criticized for allegedly using ashes of Holocaust victims from the Majdanek concentration camp in a painting. As of 12 December 2012, the Martin Bryder Gallery in Lund had pulled the painting from exhibition. In 2017, his electro-acoustic composition Still Life - Requiem, was released on LP. The music uses only sounds from the above-mentioned ashes.
In 2019, von Hausswolff formed a new musical collaboration with the Icelandic musician Jónsi (Sigur Rós), which they named Dark Morph. On 10 May 2019, they released their first album, also titled Dark Morph. The project "promises to explore the ramifications of ongoing environmental collapse to the oceans and its inhabitants." The album consists mainly of ambient sounds, often simulating the sounds of animals and nature, and contains very few actual melodies.
Carl Michael is the father of musician/composer Anna von Hausswolff.Colin Smythe
Colin Smythe (born 1942) is an Irish bibliographer and literary agent. He is also a publisher, having founded his publishing house in 1966, and is based in Buckinghamshire, UK.
Smythe is arguably best known for publishing the first five Terry Pratchett novels and later acting as Pratchett's agent. In 1971, Smythe published Konstantin Raudive's Breakthrough, the first book in the English language on the Electronic Voice Phenomenon (EVP) and the inspiration for the film White Noise. Other authors published include George Moore, Lady Gregory, "A.E." (George William Russell) and Oliver St John Gogarty.Doktor Koster's Antigaspills
Doktor Koster's Antigaspills were an early 20th century alternative medication intended to treat stomach upset and excessive flatulence. They are best known for being administered to Adolf Hitler by his physician, Theodor Morell, to treat Hitler's stomach ailments. Morrell, regarded as a quack by Hitler's associates, administered a wide variety of unorthodox concoctions and medications to Hitler beginning in 1936.The pills active ingredients consisted primarily of atropine (an extract of Atropa belladonna) and strychnine.Energy (esotericism)
The term "energy" is used by writers and practitioners of various esoteric forms of spirituality and alternative medicine to refer to a variety of claimed experiences and phenomena that defy measurement and thus can be distinguished from the scientific form of energy. There is no scientific evidence for the existence of such energy.Therapies that purport to use, modify, or manipulate unknown energies are thus among the most contentious of all complementary and alternative medicines. Claims related to energy therapies are most often anecdotal (from single stories), rather than being based on repeatable empirical evidence.Enfield poltergeist
The Enfield poltergeist was a claim of supernatural activity at 284 Green Street, a council house in Brimsdown, Enfield, England, between 1977 and 1979 involving two sisters, aged 11 and 13. Some members of the Society for Psychical Research such as inventor Maurice Grosse and writer Guy Lyon Playfair believed the haunting to be genuine, while others such as Anita Gregory and John Beloff were "unconvinced" and found evidence the girls had faked incidents for the benefit of journalists. Members of the Committee for Skeptical Inquiry, including stage magicians such as Milbourne Christopher and Joe Nickell, criticised paranormal investigators for being overly credulous whilst also identifying features of the case as being indicative of a hoax.The story attracted considerable press coverage in British newspapers such as the Daily Mail and Daily Mirror, and has been the subject of books, featured in television documentaries, and dramatised in horror films.Extrasensory perception
Extrasensory perception or ESP, also called sixth sense, includes claimed reception of information not gained through the recognized physical senses, but sensed with the mind. The term was adopted by Duke University psychologist J. B. Rhine to denote psychic abilities such as intuition, telepathy, psychometry, clairvoyance, and their trans-temporal operation as precognition or retrocognition.Second sight is a form of extrasensory perception, the power to perceive things that are not present to the 5 senses, whereby a person perceives information, in the form of a vision, about future events before they happen (precognition), or about things or events at remote locations (remote viewing). There is no scientific evidence that second sight exists. Reports of second sight are known only from anecdotal evidence given after the fact.Fear of ghosts
The fear of ghosts in many human cultures is based on beliefs that some ghosts may be malevolent towards people and dangerous (within the range of all possible attitudes, including mischievous, benign, indifferent, etc.). It is related to fear of the dark.
The fear of ghosts is sometimes referred to as phasmophobia and erroneously spectrophobia, the latter being an established term for fear of mirrors and one's own reflections.Juice fasting
Juice fasting, also known as juice cleansing, is a fad diet in which a person consumes only fruit and vegetable juices while abstaining from solid food consumption. It is used for detoxification, an alternative medicine treatment, and is often part of detox diets. The diet can typically last for two to seven days and involve a number of fruits and vegetables and even spices that are not among the juices typically sold or consumed in the average Western diet.
This diet is sometimes promoted with implausible and unsubstantiated claims about its health benefits.List of reportedly haunted locations in South Africa
The following is a list of reportedly haunted locations in South Africa.Paranormal fiction
Paranormal fiction is a genre of fiction whose storylines revolve around the paranormal.Psionics
Psionics is the study of paranormal phenomena in relation to the application of electronics. The term comes from psi (“psyche”) and the -onics from electronics (machine). It is closely related to the field of radionics. There is no scientific evidence that psionic abilities exist.Psychometry (paranormal)
Psychometry (from Greek: ψυχή, psukhē, "spirit, soul" and μέτρον, metron, "measure"), also known as token-object reading, or psychoscopy, is a form of extrasensory perception characterized by the claimed ability to make relevant associations from an object of unknown history by making physical contact with that object. Supporters assert that an object may have an energy field that transfers knowledge regarding that object's history.There is no scientific evidence that psychometry exists and the concept has been widely criticized.Psychophony
Psychophony (from the Greek psyke, soul and phone, sound, voice) is the name given by Spiritism and some other spiritualist traditions to the phenomenon where, according to them, a spirit talks using the voice of a medium.
Spiritist Doctrine as codified by Allan Kardec identifies two main classes of psychophony, to say, the "conscious" one and the "unconscious" one. The first one, as its name says, happens when the medium assures that he has mentally perceived or physically heard something that a spirit said, having only used his voice to reproduce it. The second one occurs when the medium assures that he ignores what was said, suggesting that a spirit used his phonetic organs while he was unconscious. As happens with all sorts of classification, this one is useful only for didactic purposes. Most psychophony occurrences are neither 100% conscious nor 100% unconscious laying somewhere between the two classes.
In The Mediums' Book, Allan Kardec calls unconscious psychophonic mediums "speaking mediums".
In 1971, Konstantin Raudive wrote Breakthrough, detailing what he believed was the discovery of electronic voice phenomenon (EVP). EVP, however, has been described as auditory pareidolia.Spectrophilia
Spectrophilia is sexual attraction to ghosts or sexual arousal from images in mirrors, as well as the alleged phenomenon of sexual encounters between ghosts and humans.Sylvio (video game)
Sylvio is an indie-developed first-person horror adventure video game released on Steam in June 2015 for Microsoft Windows, PlayStation 4, Xbox One and, OS X, utilizing the Unity engine. The game is about an audio recordist called Juliette Waters, who records the voices of ghosts through Electronic voice phenomenon. She finds herself trapped in an old family park, shut down since a landslide in 1971, and she now needs to use her recorder to survive the night.
