There are 4 types of EVPs that you should know about. They are separated by class into A, B, C, D, G, and R. We will go over each class so you will be able to tell the difference if you capture an EVP.
Class D EVPs
This is the lowest class of EVPs that you can get. These are the hardest to understand, with no clear words being formed. Often times, after further examination, they tend to not be an EVP. The noises heard can be identified as background noise. There is still a chance that a spirit is communicating with you though, so don’t disregard EVPs of this class.
Class C EVPs
If you capture an EVP that sounds like a faint whisper or mutter, then chances are it is class C. With these, you may not entirely be sure what the voice is saying, so it takes some time to analyze. Like class D EVPs, they can easily be debunked.
Class B EVPs
This is the most common type of EVP that investigators capture. It is usually a word that relates to the situation at hand (i.e. a response to a question). When playing back a recording of a class B EVP, you should also be able to make it out without much analyzing.
Class A EVPs
Class A EVPs are the best of the best. This also means that they are rare. EVPs of this class can range from phrases to full sentences. Class A EVPs can also be heard without playing back a recording. They don’t happen that often, but when they do, there is no doubt that it is a ghost or spirit trying to communicate with you.
Class G EVPs
There are two other classes of EVPs that aren’t as common; class G and class R.
Class G EVPs are not very good, with G standing for garbage. Chances are, you have just picked up some natural background noise. They aren’t common EVPs because oftentimes, they aren’t regarded as an EVP as all. The recording is often debunked.
Class R EVPs
Class R EVPs are unintelligible when played normal, but when listened to backward, they become intelligible. They aren’t very common but can fall into any of the above categories. Most paranormal investigators do not encounter this type of EVP.
