The human ear is able to hear an amazing range of sound. On average, most people can hear sound in the frequencies between 20 hertz and 20,000 hertz, although that range decreases with age. Animals, for the most part, have a higher range of hearing that far surpasses the human range with cats out-hearing dogs.
Although we mostly associate the ear with hearing, the ear plays other roles. The ear also aids the body in balancing itself and where to position itself.
The ear structure is part of the auditory system and is made up of several parts. Among those parts are the outer ear, the middle ear and the inner ear. These can be further described below.
