Audiology and Hearing Aids

blue ear

Hearing loss is one of the most common health conditions, especially in people over the age of 65. Hearing loss can result from many different causes such as exposure to loud noise, an inherited condition, injury or infection and physical changes within the ear caused by aging. Hearing loss usually develops slowly over many years so you may not realize your hearing ability has gotten worse.

You should have your hearing checked if you:

Types of Hearing Loss

The ear is made of three parts: the outer, middle and inner ear. The outer ear collects the sound and directs it to the middle ear where the sound is amplified. The inner ear then converts the sound to nerve impulses that go to the brain.

There are two basic types of hearing loss, conductive and sensorineural, and you may have one or both types. A conductive loss occurs in the outer or middle ear when sound waves are disrupted before reaching the inner ear. A sensorineural loss (also called “nerve deafness”) occurs when the nerve signals are disrupted on the way to the brain.

Hearing Evaluation

If you suspect a hearing loss, you will want to have a complete evaluation. This evaluation consists of a series of diagnostic procedures designed to find out what type of hearing problem exists and what treatment procedures you might benefit from. An audiologist will perform several different tests that will be used to accurately and completely diagnose your hearing problem.

Types of Hearing Aids

After the hearing evaluation, an audiologist will perform additional testing and counseling to determine what type of hearing instruments will meet your needs. There are four main types of hearing aids. Special features and accessories are also available for each type to assist you to achieve your best possible hearing level.

Behind-the-Ear

Behind-the-Ear hearing aid

Behind-the-Ear aids can be used for mild to profound hearing loss. The components are worn in a case behind the ear, and sound is conducted to an ear mold through a plastic tube. Their controls are generally larger, which may be easier for some people to adjust.

In-the-Ear

In-the-Ear hearing aid

In-the-Ear (ITE) aids can be used for mild to severe loss. All components are contained in one case that fits in the outer ear and partially extends into the ear canal.

In-the-Canal

In-the-Canal hearing aid

In-the-Canal aids are used for mild to moderate hearing loss. This case is more compact than the ITE type and fits in the ear opening and canal.

Completely-in-Canal

Completely-in-Canal hearing aid

Completely-in-Canal can be used for mild to moderate hearing loss if the person has a relatively straight ear canal. This type of hearing aid is almost invisible when worn.

Hearing Aid Fitting

After the hearing evaluation and hearing aid selection, an audiologist will fit and teach you about your aid so you are able to function independently with your hearing aids. This will include instruction on: hearing aid parts, hearing aid programming, daily hearing aid cleaning and use, using the telephone and how to manage hearing aid batteries.
