Thanks for that input Richard, I couldn't think of "resultant" when I wrote this the other night. You pose an interesting question about supersonic freq. producing resultants. It would be a little more difficult to demonstrate - where would you find an oscilator to produce an supersonic tone? Perhaps if fed into a sound system, the resultant could be amplified while the supersonic fundamentals would be too high for the speakers to reproduce. Yes, I do think the Tantric Monks produce tones lower than 20 cps. I may, however, be a resultant frequency that we hear. They are actually trained to produce 3 independant tones simultaneously with their vocal chords. (I didn't say it was pretty, just interesting!)
