When do the concepts of Isochronic tones and Monaural beats originate from?
I’m trying to do research for a class of mine on the subject of auditory suggestion. I’ve come across plenty of information concerning Binaural beats and their conception, but the other two terms that I mentioned seem to have no history of discovery. Is there any information out their concerning their discovery?
