Electronic Voice Phenomena

EVP stands for Electronic Voice Phenomena. Somehow the spirits are able to manipulate ambient energy, more typically sound energy, and are able to somehow form a voice.

Paranormal researchers believe they are able to manipulate the electromagnetic workings of the electronic voice recorder. Ghost hunters have the tendency to hear what they want to hear from the tapes. They know what questions were asked and have an idea of what answers to expect. Because the technique's authenticity is impossible to prove no tape, regardless of what's recorded on it, can be considered hard evidence. Critics have a valid point when they say that the sounds or voices recorded are either natural noises or hoaxes. There's no way to prove that they're wrong.
