[edit] meaning of critical band rate

The meaning of this term is not explained. I can guess at it, but ...! yoyo 08:02, 17 March 2006 (UTC)

[edit] critical band edges

Saying that the critical band edges fall at 0, 100, 200, 300, etc Hz seems to imply that the frequency spectrum is partitioned precisely by those frequencies into non-overlapping regions. But the explanation at critical band implies rather that at any frequency, there are sounds at both higher and lower pitch that the initial pitch will mask. If that is so, what I think this article ought to be saying is that the critical bandwidth increases (non-linearly), and tabulating the bandwidth for a sequence of increasing initial pitches. Unless the basilar membrane has a number of sharp discontinuities in its response curve, I don't see how it could possibly partition the spectrum in the manner indicated. yoyo 08:02, 17 March 2006 (UTC)
