About Your Hearing

There are three basic parts to the ear: the outer ear, the middle ear, and the inner ear. The outer ear, or the pinna, is the piece of flesh we see attached to the side of the head which also includes the ear canal. The outer ear catches sounds and funnels it into the ear canal.

These sounds then vibrate the ear drum, or tympanic membrane, which is attached to the end of the ear canal. This is the beginning of the middle ear. Beyond (and attached to) the ear drum are three tiny bones, called ossicles, which move in response to the vibration of the ear drum. The ossicles then transmit the sound to the inner ear.

The inner ear, is filled with fluid. The movement of the ossicles causes the fluid within the cochlea to move. The movement of the fluid stimulates tiny nerves called hair cells. Each of these tiny nerves are responsible for specific frequencies. When the hair cells are stimulated by the movement of the fluid within the cochlea, they send an electrical impulse along the hearing nerve to the brain creating the sensation of hearing.

If you suspect that you or your loved one has a problem with their hearing, ensure optimal hearing healthcare by having a hearing test today.
