EVP research has produced many thousands of these 'Voices'. Categorization varies from researcher to researcher. For the purpose of this web site, here are the classification we will use.

Classes of EVP......

Class A:
Voices are very clear and easily understandable by many.

Class B:
Voices are fairly loud and clear and are sometimes audible without headphones.

Class C:
Voices are very soft and often indecipherable. These tend to be researcher dependent.
