I don't understand the 'paradox' here. You can hear the difference between
an impulsive sound low-passed below 20 kHz and low-passed below 26 kHz. That
does not mean that you should be able to hear a pure tone, ramped up slowly,
at +/-24 kHz. It would be the case only if the cochlea performed an exact
Fourier tranform...
