Grading Your EVPs
Most are familiar wit the common Class A, Class B, and Class C designation used to grade EVPs. It seems to be the one many use because it is simple. But it is also not very descriptive. I have been using a different method for some time which not only clarifies how clearly it is heard but also tells a bit more about the content. It is comprised of three categories with designations in each.
The system works by simply selecting the appropriate letter and number from each column in the table below:
Quality Grading:
- _A_ Heard and understood clearly without any signal processing at all, Like a normal voice (rare)
- _B_ Analog or High qulaity digital recorder employed. Analog bandpass filtering to bring out voice. Most agree on what is said.
- _C_Analog or Digital Voice recorder. Hard to hear. Some disagreement on content and some may not hear it at all. (Most common valid EVP)
- _D_Digital processing employed to make out anything at all. Disagreement over content, some may not hear anything. Digital artifacts are a possibility (Also common but not reliable)
- _E_Most hear nothing; some may claim to hear a voice. Processing may result in different messages being heard. Likely these EVPs are artifacts of processing. (Probably not a true EVP at all, likely wishful thinking on the part of the listener)

Content Grading:
- _1_Easily related to surroundings. For instance: A soldier who was killed mentioning the battle, etc.
- _2_Unrelated but meaningful, such as a statement "I love you". Could be for anyone or maybe no one present.
- _3_Gibberish. Meaningless groups of words but still recognizable as words or phrases.
- _4_Utterances. Vocalized sounds not words. Includes grunts and groans. Before classifying here make sure you are not dealing with a foreign language which should actually be in categories 1-3.
- _5_Non vocal sounds. Thumps Bangs, Pops, Footsteps, etc.

Source Grading:
- _U_ Multiple voices heard, unable to differentiate.
- _V_ The gender or age cannot be determined.
- _W_The voice is clearly that of a child.
- _X_ The voice is clearly that of a woman.
- _Y_ The voice is clearly that of a man.
- _Z_ The recording is of an animal sound (Barking, Meowing, Vocalizations only)

To Grade your EVP, select the appropriate letter from the first column, number from the second column and finally letter from the third. For example, if you got a male voice with aconsiderable other noise, on a digital voice recorder, at a battlefield say, I hurt!" the classification would be, C-1-Y
Note that many EVPs may contain portions falling into multiple categories. Parts may be clear then fade out. Vocalizations may be preceded or followed by non-vocal sounds. Thus a particular EVP may have multiple classifications. If you are classifying the overall EVP, use the most predominate characteristics.
