@R. David Case, you already know that I think that this sound therapy may be legitimate and I don't think you are a liar, but you need to wise up about some of the technology because I am about to mercilessly humiliate you if you don't drop this "muh EMF from muh Koss coils reaches muh brain" nonsense. Seriously dude, I think you have something good here but you're pooping all over it with your Art Bell Coast 2 Coast level mentally ill crap. I taught college level electronics for a few years and I am telling you you are a friggen dumbass if you think the EMF from low current, low voltage headphones is penetrating the skull or reaching the cochlea. Seriously bro, I love you, but just stop. If anything is having an affect it is the random, HF noise. I am 100% on board with your notion that this should be done at night and I think you have a real winner here but fuck damn, your babbling about SIGINT and the like is just ridiculous. I really do believe that you 555 timer circuit is unique and very interesting, but only for the sound, nothing else. I like you bro, but come back down to earth please.
