====Electronic voice phenomena====

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