niels, the sampling theorem has nothing whatsoever to do with human
hearing. it is pure information theory, and demonstrably correct. asking
somebody to prove it all over again is a really stupid thing to do. the
intelligent way to get rid of the sampling theorem is to provide a
(mathematically rigorous) counter example. don't waste your time searching.

if you want to explore new ways of understanding human hearing, then by
all means do so. but don't jump to false conclusions about fundamental
mathematical truths. you will find that reading (and actually trying to
understand) a paper or two might indeed help.
