When I was little and reading anything that had to do with ghosts in our elementary school library, I constantly checked out a book called "Phone Call from a Ghost" by Daniel Cohen. The book featured true ghost stories and some very eerie, well-done pencil drawings that scared the hell out of me. The title of the book itself was scary. The very idea of getting a phone call late into the night and hearing a hollow sounding voice of someone who has died on the other end sends shivers down anyone’s spine.

But what if we could get a phone call from the otherside? Would you accept the call? Would that make you a believer that we do in fact continue on in some form or another? EVP or Electronic Voice Phenomena is the closest thing to getting a "phone call from a ghost." Essentially, EVP is the process of recording the voices of those who have passed on. The voices are never heard during the recording session but appear during playback. Sometimes the voice is hard to decipher and barely audible. Other times, a voice comes through so clear there is no doubt in anyone’s minds what was said.

You might hear about an EVP being a "Class A" or "Class C". Sarah Estep, who founded the American Association of Electronic Voice Phenomena divided EVP's into three catagories.

  • Class A: Extremely clear and the words are easily heard. There is usually no confusion on what the voice is trying to say.
  • Class B: Some words come out clear, others don't. The sentence may start clear but fade out or become jumbled.
  • Class C: You know there is a voice there but good luck deciphering what it said. Most of the time the voice is way too quiet or muffeled to make anything out.
