THE
FIVE MOST OFTEN ASKED QUESTIONS OF AN AUDIOLOGIST
1.
What is an audiologist?
An audiologist
evaluates hearing and offers rehabilitation services to individuals with
hearing loss. Rehabilitation services may include fitting of
amplification (hearing aids), assistive devices, and therapy.
Audiologists also do special testing such as central auditory processing
testing and balance testing (ENG).
2.
Who can have a hearing test?
Anyone can have
his hearing tested. Even newborn babies can be evaluated accurately by
using one of two test procedures. Otoacoustic emissions (OAE) measures emissions of sound energy from
the nerve fibers in the inner ear through a soft rubber probe placed in
the ear canal. Auditory Brainstem
Response (ABR) measures activity from the auditory nerve through
flat disk electrodes taped to the forehead and ears.
3.
How does an ear infection affect hearing?
Fluid
will build up behind the eardrum when the Eustachian tube, the airway
between the middle ear and the throat does not function properly. The
role of the Eustachian tube is to ventilate the middle ear space. When
this does not occur, pressure builds up behind the eardrum. This will
eventually cause the space behind the eardrum to fill up with fluid.
This will result in decreased hearing. Sound cannot travel through fluid
and the eardrum cannot move normally with fluid behind it. Repeated
episodes of otitis media during infancy and early childhood can result
in auditory deprivation during the most important time of life for
language development. Children who experience mild hearing loss due to
fluid in the ears are at risk for delayed speech and language
development.
4.
What types of hearing aids are there?
There are many
different styles and sizes for hearing aids. Hearing aids range in size
from very small completely-in-the-canal instruments to larger
behind-the-ear models. In addition, the electronics in hearing aids can
vary from non-computerized units to fully digital instruments. The type
of electronics determines the sound processing capability and features
that the aid offers.
5.
Are there people who do not benefit from hearing aids?
Some
individuals with limited residual hearing receive only marginal benefit
from hearing aids. Amplification may result in sound awareness but
little or no speech understanding. If the best possible hearing aid
provides less than 40% speech understanding, the patient may be a
candidate for a cochlear implant, a device that is surgically inserted into the
inner ear.
