What limits the frequency response of human ear?
To answer why the human ear can’t hear very high frequencies, you first need to know how the ear hears. http://www.ehow.com/how-does_4574056_the… Psychological disturbances, social and emotional handicaps, and significant reductions in mental and physical functioning are known to be associated with advanced levels of hearing loss in elderly people, but the main physical reasons are the aging of the auditory system, just as the rest of the body loses its youthful resiliance. For example, in the middle ear, there is a reduction in the flexibility and ease of vibration of the three bones– the malleus, incus and stapes (hammer, anvil and stirrup) –that are connected to the eardrum in series. There is no absolute rate of hearing loss. At 79, my hearing extends beyond 10khz (barring a couple of holes which occurred at about age 21 due to three combat tours in Korea). .
