These phenomena were subsequently investigated by Hans Bender
(a German parapsychologist) and Konstantin Raudive (a Latvian psychologist). Following the 1971 publication of Raudive's book on his research, EVP are also often referred to as "Raudive Voices".
What Is EVP?
It has been argued that the "voices" are simply subjective intepretations - that the human ear tends to hear voices in random patterns of sound. It may be possible that the human brain has an in-built tendency to create these perceptions even when there is no "objective" basis for the experience. There are those, however, that believe EVP to be genuinely mysterious, even paranormal. Some even believe they open up the possibility of communication with the dead. For believers, the fact that the speech is difficult to understand can be explained by the fact that the communicating spirit may be talking in a language or dialog that is not in common usage today.
A Real EVP Recording
This was sent to me by Kim. She has sent me many photos which you can view in the Guest Gallery. In this EVP recording, you can hear a voice saying, almost in agony, ..."Save Me."
You might have to play it a couple of times but you can't miss it. This recording has only been enhanced by myself using a sound editing program. The reason was to cut down on the "noise" and "bring out" the actual voice.
