EVP

Electronic

Voice

Phenomena

Electronic voice phenomena (EVP) are electronically generated noises that resemble speech, but are not the result of intentional voice recordings or renderings. Common sources of EVP include static, stray radio transmissions, and background noise. Some have claimed these sounds are of paranormal origin,while there are natural explanations such as apophenia (finding significance in insignificant phenomena), auditory pareidolia (interpreting random sounds as voices in their own language), equipment artefacts, or simple hoaxes. Recordings of EVP are often created from background sound by increasing the gain (i.e. sensitivity) of the recording equipment.

Parapsychologist Konstantin Raudive, who popularized the idea, described EVP as typically brief, usually the length of a word or short phrase.

Phone calls from the dead""Phone calls from the dead" is an alleged paranormal phenomenon in which people receive telephone calls that they claim are from spirits of the deceased. People have reported receiving telephone call from deceased relatives, friends, or even from someone not directly known by the recipient in life. The communication is usually simple and brief, and is usually a one-time occurrence. Physics

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 though 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.

Capture errors are anomalies created by the method used to capture audio signals, such as noise generated through the over-amplification of a signal at the point of recording.

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 previous audio recordings not being completely erased. This could allow a small percentage of previous content to be superimposed or mixed into a new 'silent' recording.

Paranormal groups and ghost huntingInvestigation 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.
