Why do most hearing aid wearers have two hearing aids?
Why has nature provided us with two ears when one ear will allow us to hear? Nature has shaped and located our ears in a cleverly calculated manner. The outer part of an ear protrudes from the head at a specific angle collecting sound waves, which enter the ear canal and go directly to the eardrum. These sound waves are carried through the middle ear cavity along three delicately small bones to the hearing nerves of the inner ear. The fluid-filled inner ear is one of the wonders of creation. Packed into a space the size of a large garden pea, in this fluid are found the organs of balance, acceleration and deceleration sensors, and over 20,000 hearing cells each tuned to a different frequency. The sound waves create motion in the inner ear fluid, which causes the tiny cells to generate an electrical impulse, which is carried to the brain. The brain functions to interpret these impulses and gives them meaning. Thus, we hear with our ears, but understanding what is heard takes place in th
