Hearing and Hearing Loss The auditory (hearing) system consists of three sections, each with very important purposes. The first section is the outer ear which includes the pinna and external ear canal. The outer ear protects the rest of the ear from foreign objects, it also amplifies sounds that arecollected, and helps us to determine which direction sounds arecoming from.The middle ear is an air filled space that begins at the eardrum.The eardrum vibrates to incoming sound which results in themovement of three small bones (the malleus, incus and stapes)attached to the eardrum. At the end of the stapes is the ovalwindow, an opening into the fluid-filled cochlea, or organ ofhearing.The cochlea is the auditory portion of the inner ear. It is fromhere that sound is transmitted to the auditory nerve. A problemin any one of these areas may cause either a conductive,sensorineural, or mixed hearing loss.Conductive means there is a problem in the outer ear or middleears, such as excessive ear wax in the ear canal, fluid or infectionin the middle ear, or perhaps a hole in the eardrum. It is usuallymedically treatable.
With sensorineural, there is a problem with the cochlea orauditory nerve due to aging, noise exposure, or family history. Itis usually treated with amplification devices. Rarely, it is causedby a benign tumor, in which case, surgery is necessary.When there is both a conductive and sensorineural loss, it isconsidered to be mixed. If you or a loved one thinks you may beexperiencing a decrease in hearing, contact your physician oraudiologist.
