Re: Hiraga on Feedback

Yes, there is a whole lotta blending goin' on. I agree that the single-tone case lacks precision when applied to the multitone case, but in its favor the single-tone case allows us to get a grip on the fundamentals.

Besides bringing out strident intervals it's also possible for musical IM to *mask* them. To quote myself again: "The blending effect can be easily tested with a guitar. For example, playing F (below open E) together with open E causes objectionable beating. Adding an A intermediate to the two tones smoothes out the subjective effect considerably. The interval of F with E is a major seventh (8:15). Adding the A, however, creates two new intervals: a major third (4:5) and a perfect fifth (2:3). The two consonant intervals then "swamp out" the one dissonant interval to create an overall composite consonance. The critical parameter for composite consonance is thus not masking, but blending."

I am saying here what you are saying, John, that even a slight out of tune or out of phase resonance or IM can throw off an otherwise consonant blend of sounds. The masking effect is a small part of this equation, which equation I think is far more complicated than Cheever makes it out to be. Consonance or dissonance are the result of the composite waveform as it strikes the ear, and this includes room effects.
