here are a couple of things about evp:
white noise was the crappiest movie ever made (yes, that includes Head by the Monkeys).
evp is pure male bovine excriment. when they show evp on tv(or you can find some on the net), don't look at the words they give you. if you don't look, all you hear is static. look and your mind thinks it hears what is written.
maybe that would be a good project. show how evp is fake. get a "sample" and play it once with the words covered, then again with them showing. see if you hear the "voices."
