Classification of EVPs.

EVPs range vastly in quality and are evaluated and sorted by their clarity and volume. Classifications ultimately determine the risk taken in calling them "paranormal". The following are the most commonly used conventions for classification:

Class A:
heard clearly without the use of headphones and listeners will generally form a consensus about what is being said (even if that consensus is that they cannot agree on what is being said);

Class B:
audible yet difficult to hear without the aid of headphones; frequently there will be some disagreement about its message, or disagreement over the assumption that there is a message;

Class C:
will scarcely be heard without the aid of headphones and filtering (such as equalization); the wording will likely be indiscernible and very speculative.

Class R:
in this controversial classification, EVPs are recognized by reversing the audio clip, making the transcription of such an EVP very unreliable because there is such a strong potential to matrix the words. In fact, because the obscured sound quality of most EVP places them in Class C and B, any transcription should be regarded as suggestions only, and not verbatim quotations; everyone therefore is advised to keep a skeptical view of their interpretation and to be aware of the potential for auditory matrixing.
