Electronic Voice Phenomenon (EVP)
Preferred term for the phenomenon discovered by Friedrich
Jürgenson in 1959 and extensively developed by the experiments
of Konstantin Raudive (1909–1974). The phenomenon
is often referred to as Raudive voices. Raudive voices,
apparently from dead individuals, are electronically impressed
on tape recordings made on standard apparatus (sometimes
enhanced by a simple diode circuit). The voices have also been
discovered on the ‘‘white noise’’ of certain radio bands. This
discovery, backed by thousands of experiments, has been seen
as a way of obtaining communications from dead persons
through electronic apparatus instead of Spiritualist mediums.
However, some experimenters believe that the voice phenomenon
is ambiguous or capable of mundane explanation, such as
being the result of radio sources or even wishful thinking.
George W. Meek developed an apparatus, the ‘‘spiricom,’’ for
use in testing the possibilities of more unambiguous Raudive
voice data.
