See also the articles on this on audiomisc in the 'hearing' section which
also considers hearing nonlinearity in this context.

Thanks for the pointer. I have looked at your "Ringing in the Ears"
article. I believe it confirms precisely what I suspected. There's
a possibility that some effects which in a linear hearing system would
be innocuous may be audible with real-world non-linear hearing. At
least it seems that the possibility cannot be excluded without
further checks.

I was wondering also about the issue of whether the linear system
equivalence of frequency-domain and time-domain signals might not be
preserved in non-linear human hearing. That is, does the "normal"
20 Hz - 20 kHz human-audible bandwidth imply an equivalent ability to
resolve time-domain differences or does non-linearity break that
equivalence?
