In Reply to: If you think there is audio at and beyond 20-kHz, how do you resolve the fact.... posted by John Elison on September 27, 2005 at 16:03:27:
It takes a lot of second order distortion to be heard; I seem to recall that the threshold is something like 2-3%.Of course 10% should be audible, or at least it will have an effect of some kind.....

I really don't think anyone can audibly detect distortion at 20-kHz, which would be 20-dB below the fundamental. Of course, I could be wrong.
Anyway, that’s why I think that vinyl doesn’t sound so bad. Its greatest distortion is at high frequencies leaving only 1% to 3% at low frequencies.
