Yeah. I was kind of aiming in woo-woo land there, as it seemed appropriate for the thread, but altering audio, video, or magnetic frequencies within range can affect your mood.
I'll agree with all of that except the very last statment. There is absolutely NO indication of ANY kind that "alternating magnetic frequencies" has any effect on the human brain. If you know of a study that proves otherwise, I'd certainly be interested in reading it. (Not from some woo-woo site, of course.)
