AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-low carrier frequency
"Jeff Liebermann" wrote in message ... isw hath wroth: I beg to differ. There's no mixing happening in the air. compression of air is very linear (Boyles Law or PV=constant). In general, that's true, but take a look at what happens in the throats of high-powered horn loudspeakers. You can find info in e.g. "Acoustics" by Beranek. Isaac What am I suppose to look for? I appreciate your recommended research project, but frankly, I don't care what happens inside a high powered horn loudspeaker. I prefer to stay fairly on topic about the original allegation that mixing somehow occurs in open air, which is not true. Incidentally, if mixing did occur in open air or inside the ear, you would not be able to comfortably listen to hi-fi music, as all you would hear would be intermodulation products. Yes everything would become ultra sonici |
