since the Humans can generally hear sounds with frequencies between 20 Hz and 20 kHz (the audio range). we could differentiate MP3 audio encoded at 22khz and 44 khz if the above concept is true , we must not be able to hear them ! right !
explain me !!

Well, not exactly. Unless the bit rate is way higher than the highest frequency to be sampled, other factors enter the picture, such as aliasing. These considerations cause a degradation of the harmonic structure of the upper frequencies. Then, there are the compression codecs which can also degrade the sound. We humans can hear the "distortions" inherrent in formats that (just looking at sample rates) would all seem to be adequate.

I think you'd have to ask someone who works at the audiology place at the hospital to find out this since they know more about audiololgy and stuff like that. Sorry.
