Electronic voice phenomenon (EVP) refers to the purported manifestation of voices of the dead and other discarnate entities through electronic means. This has typically involved tuning radios between stations and recording the output on audiotape, although more recently anomalous voices, visual images, and text have purportedly been found using telephones, television sets, and computers in a phenomenon known as instrumental transcommunication. Given the lack of documentation of EVP in mainstream scientific journals, a review of its history is given based on English language information found in psychical research and parapsychology periodicals and various trade publications and newsletters. An effort was made to replicate EVP by having research assistants simulate interaction with discarnate entities while taping the output from 2 radios tuned between stations onto audio cassettes. There were 81 sessions with an average of approximately 45 min per session for a total of about 60 hr and 11 min of recording. Al though there are some apparent voices and interesting noises on playback, none of these are sufficiently distinctive to merit being considered anomalous. Some speculative reasons are given for the negative result, although the possibility that there are no anomalous phenomena associated with EVP is offered as an explanation for consideration alongside the hypothesis that experimenters create EVP effects through anomalous human-machine interactions and an exosomatic theory of actual influence of electronic equipment by discarnate entities.
