The HIGH from a wave form is called a Bi-Neural beet. One freq in one ear and a slightly different beet in the other causes an offset in your BRAIN (BRAINS , mmmmmmm). 100Hz in the left ear and 105 Hz in the right gives you a cognitive beet of 5Hz, which is in the DELTA brain wave area. I use them to help with sleeping. I have had insomnia since I was a child an now I sleep semi-normally. Nothing is perfect and isn’t everything a trick of the mind? Love the show. YOU GUYS ROCK!!!!!!! (said in Molly’s screaming rock voice). Live life Don’t just observe it Simien – OMG! Double Rainbow! One Unicorn!
