I don't think I understand how it could sound different to my ear. My understanding is that my ear doesn't have the sensory equipment to detect signals above ~20kHz - this is what I was told at university, and a decent trawl of the web suggests this is still true. If there is any sound that is in the range 20Hz-20kHz then why doesn't the microphone pick it up?

Or am I wrong, and the ear is able to detect frequencies above 20kHz?
