What is EVP?
Electronic Voice Phenomena is the result of unintentional sounds and/or voices being captured and recorded on electronic audio devices. EVP is commonly found in recordings with static, stray radio transmissions, and background noise.
What causes EVP?
There are a number of natural reasons behind possible EVP, these include, but are not limited to, apophenia (finding significance in insignificant phenomena), auditory pareidolia (interpreting random sounds as voices in one’s own language), general equipment noise, and hoaxes.
EVP and the Paranormal
One of the most common, and often strongest, pieces of paranormal evidence comes in the form of EVP. As audio recorders are much more sensitive than human hearing, they are much more likely to capture any sounds that are too quiet for us to hear or that may be lost in a lot of background noise. A good quality audio recorder should always be part of a paranormal investigator’s basic equipment.
An EVP can be hard to hear and can often be debunked. Even most unexplained EVP often has to be discounted depending on how clear the sound or word is on the recording. Suspected EVP is placed into one of four categories.
Class A – 100% audible, clear voice & intelligent or reactive responses, as opposed to random noise or words. For example, having direct questions responded to. Audible to the human ear with no enhancements needed, and no question to what the voice is saying.
Class B – Practically audible only by using sound analysing Software via a computer where the audio can be enhanced. Some doubt to the interpretation
Class C – Frequency levels support this unexplainable voice. It’s not always audible, but some constants are present. Timing & tone apply to this category. Direct response is not required and only by enhancing the audio file can we determine whether this is Paranormal or not.
Class D – Whispers, faint murmurs, breath like sounds and airy sounding voices. These may be EVP, but it is too questionable to declare as paranormal. Usually Class D EVP are not published.
Most EVP captured falls between classes D and C, but EVP that is published as possible paranormal evidence tends to fall between classes C and B. It is extremely rare to capture a genuine class A EVP
