EVP (Electronic Voice Phenomenon) An EVP is a disembodied voice that you cannot hear at the time of the investigation, but when you listen to your audio recordings there are voices on the recording that cannot be explained. EVPs can come through any type of audio recording device such as audiocassette recorders, digital audio recorders and even video cameras. EVPs come in a wide range of styles. Some EVPs are loud and clear, while others are much softer and need headphones or amplification to hear. Some EVPs are also either low, garbled or otherwise unclear. While there could be many reasons why EVPs come in such a wide variety of styles, to better help describe the characteristics of an EVP, paranormal investigators and researchers often use a classification system to rate the quality of EVP recordings.
The follow is the classifications of EVPs that are generally accepted and used by paranormal researchers and investigators:
Class A – This type of EVP is loud, clear and of very high quality. The voice is easily understandable and does not need enhancement or amplification. Everyone listening to the EVP will agree on what is being said.
Class B – This type of EVP is of somewhat lesser quality and clarity than a Class A EVP but still very audible. Class B EVPs may need some amount of enhancement or amplification to be heard clearer. Everyone listening to the EVP will be about a 50/50 split as to what is being said.
Class C – This is the most common type of EVP. This is a lower quality EVP. A Class C EVP will need some amount of enhancement and/or amplification to be heard clearer. There may even be debate whether or not an EVP is actually present. Everyone listening to the EVP will have their own opinion as to what is being said. There will be a variety of possibilities of what is being said.
Class D – These are very poor quality EVPs. Extremely questionable if it is even an EVP. Also referred to as EVP chatter, whispers, breathing noises and airy sounds. Some investigators use Class D as a “holding” classification until further analysis is performed. Either way, Class D EVPs are not used as presentable evidence.
