Electronic voice phenomena (EVP) were first discovered by the Swedish artist Friedrich Jürgenson in 1959. J�rgenson was recording birdsong using a reel-to-reel tape recorder. When he replayed the tapes, he heard faint but intelligible voices in the background, even though there was no-one else in the vicinity when the recordings were made. By repeating the procedure, J�rgenson found that the voice recordings could be reliably replicated.
