Today, one of the rising interests in paranormal investigation is the use of electronic voice phenomena, or EVPs. As such, the SPIRITS of St. Petersburg has begun a collection of favored EVPs from our investigations.
As a starter, we begin with some EVP factoids:
*(Debated): EVPs may actually associate with the origin of the telephone, which was designed to contact the dead. Edison, himself, was alleged to have begun working on a device to record voices of the dead but died before its completion. (AAEVP denies this).
*The first EVP is believed to be captured on a phonograph in 1936 by American photographer Attila von Szalay.
*In 1967 Fedrich Jürgenson advanced the study of EVPs. Jürgenson’s interest in Electronic Voice Phenomena apparently began when, after having recording bird songs with a tape recorder, he could hear human voices on the tapes, even though there had been no one in the vicinity.
*In 1982 Sarah Estep founded the American Association of Electronic Voice Phenomenon (AAEVP), an organization designed specifically for the study of EVP research. This organization continues today.
Class "A": voices can be heard and identified by anyone with normal hearing and knowledge of the language spoken; no special training of the ear is needed to detect them.
Class "B": voices speak more rapidly and more softly, but are still quite plainly audible to a trained and attentive ear.
Class "C": voices can be heard only in fragments, even by a trained ear, but with improved technical aids.
Issues with EVPs:
Several sites do discount EVPs as relating to natural phenomena. They argue that EVPs can be produced by overlapping airwaves filled with cell phone calls, TV and radio waves, and other technological functions mistakenly captured by investigators. http://skepdic.com/evp.html
