This new concept speaks about the reversed processes of analogus extensio requiei found in the foregoing work called Monoscope, received from hypothetical afterlife noise.
Though he worked as a painter and film director, Friedrich Jürgenson (1903-1987)
is best known as the pioneer of electronic voice phenomena as know as EVP.
An initial field recording of local birdsongs, fueled by a passion for ornithology, led him to a 28-year study of what he believed were spirits communicating with us through sound recording technologies. He continued his work searching the origins of his voices that he believed to be deriven from the hypothetical afterlife until his death in Sweden in 1987.
In the spring of 1959, he became convinced that the electrical appliances were actually able to act as transmitters for what concerns the unconscious impulses, feelings and thoughts: they could be recorded on tape. Several months after he moved with his wife Monica in their summer residence and began to record the verses of some birds, listening to the recording, he noticed a strange and unusual vibrating noise. Listening to the tape, he thought he could distinguish the voice of his deceased mother. From then on, he continued his research on these phenomena and was initially led to believe that they were messages of non-terrestrial, but soon became convinced that those voices were coming from the other side: that day was born the EVP.
In his experiments, tuned in to the radio in the mid-range frequencies, in such a way as to have a variation of perceived noise. Some time later, he stared at frequencies between 1445 kHz and 1500 kHz. The 1485 kHz frequency is still called today
In 1985 he held his last press conference in conjunction with a television appearance. Two years after Jürgenson died, and left several hundred tapes still preserved.
