I'm surprised that this mis-conception continues to be voiced... The point of the higher sampling rate IS NOT any belief that humans can hear beyond 20kHz, and I know for a fact that I can't even hear that high (16.5kHz left, 17.2kHz right when last measured). The point is that designing an anti-aliasing filter that is perfectly flat (amplitude and phase) to 20kHz, and is 96 db down by 22 kHz is pretty much impossible. As a result, many anti-aliasing filter designs have measureable affects inside the audible passband (ie below 20 kHz). Shifting the sampling rate up, moves the whole filter response problems up as well, into an area where theres no chance of them being audible.
