It is believed by many that this Phenomena occurs when the voices of a Spirit/Ghost interrupts the Electro Magnetic Field, "E.M.F's" However, most scientists have dismissed all the thousands of voices recordings since first discovered in the 1950s. Among the many explanations given by the scientists are outright fraud, stray signals from a TV or radio station to the active imagination of ghost hunters and mediums.

It is true that these explanations can account for some of the E.V.P.’s. However, sometimes not only are the detected voices remarkably clear but they seem to be interactive as well. Some of these voices appear to be able to even answer questions and join in a conversation.  

A voice recorder /Tape recorder is supposed to be able to reveal these voices which cannot be heard by a human ear, in the same way as a dog-whistle. The dog in this case being the voice recorder. Humans ears cannot pick up the sound of the dog-whistle because the frequency is to high, where as the dog’s ear drum, is designed for hearing higher frequencies.

So although we can never be certain that E.V.P's really are that of a Spirit or Ghost. Here are some unexplained voices we have recorded. They are NOT the voices of any group member and were taken when no one else was around.
