Electronic voice phenomena (EVP) were first discovered by the Swedish artist Friedrich JŸrgenson in 1959. JŸrgenson 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, JŸrgenson found that the voice recordings could be reliably replicated.
