Can human hear 20K Hz and above?

Yes, we can. By means of bone conduction we can hear up to 50 kHz, and values up to 150 kHz have been reported in the young (Pumphrey, 1950). However, it is indeed generally agreed that 20 kHz is the upper acoustical hearing limit through air conduction. read more

Who reported humans can hear until 20 kHz range are the psychophysicists who studied the methods of hearing in animals and their animal experimentation and not these answerers. \U0001f923. Not all humans can 20kHz range. I can’t hear until 20kHz. The hearing range ability depends on each human. read more
