A new article on electronic voice phenomena

A fascinating subject, I am most intrigued by the final paragraph in the article, as that has been my assumption for that past 30 years, or so:  There is a real and currently unexplained phenomena going on, but it seems to be centered on the person(s) present at the recording session. Such would explain why EVP isn't more common, (there must be many thousands of hours of recordings taking place all over the world ever hour, and yet EVP remains confined to those folks specifically searching for it); and that the language spoken is always one that can be understood by the participants.  I'd also note, that over 40 years of research and recordings hasn't really advanced out understanding or communication with these supposed 'dead' folks.  Not much more is known now then in '74 when I first heard about it.
