Why Have a Diagnostic
Hearing Evaluation?
Having a diagnostic hearing evaluation is the first step in
determining the type, degree, configuration and symmetry
of your hearing loss. Your evaluation includes a variety of
measurements to rule out any medically treatable causes
of hearing loss.
Untreated Hearing Loss Can Have Adverse Effects
The inability to remain alert to everyday environmental sounds
and maintain good communications with others can cause not only
embarrassment, but may have serious consequences. A person with
a mild to moderate hearing loss may be at risk without knowing
it. Research has confirmed that hearing loss can have adverse effects
on an individual's ability to function and upon several aspects
of life. This includes family relationships, enjoyment of social
activities, performance in work settings, and potential danger
from failing to hear warning devices or even hear the doctor's
instructions regarding proper use of medications. The 1999 Hearing
Industries Association and National Council on Aging study clearly
demonstrates that individuals who go untreated for hearing loss
report significantly more feelings of depression, paranoia, anger
and frustration than hearing aid users.
Why It's Important to Have a Diagnostic Hearing Evaluation
A Diagnostic Hearing Evaluation determines the type, degree, configuration
and symmetry of your hearing loss. This includes a variety of measurements.
One of our skilled audiologists will perform the diagnostic hearing
tests. If testing reveals you are a candidate, we will make an
evaluation of your lifestyle and personal goals before determining
the best hearing aid style for your particular hearing loss. Your
personal decision to wear a hearing aid, combined with realistic
expectations, are the first steps to improved hearing.
A Brief Overview of Types of Hearing Loss
Only 5% of hearing losses in the adult population are the result
of mechanical or structural damage to the ear (i.e., the outer
and/or middle ear). This type of loss is called a conductive hearing
loss. Common causes are impacted wax, perforated eardrum, middle
ear effusion, otosclerosis, cholesteatoma, and congenital anomalies.
In most other cases, the patient can receive partial or complete
restoration of hearing through medical/surgical intervention.
In nearly 95% of the adult population with
impaired hearing the problem is located in the inner ear (cochlea),
resulting in a sensorineural
type loss, commonly called "nerve deafness." In these
cases, there is a degeneration or damage to the microscopic hair
cells (receptors) or cilia in the inner ear. This causes irreversible
hearing loss. In the vast majority of patients, these hair cells
will function well if stimulated more vigorously with amplified
sounds. The most common causes of sensorineural hearing loss are
noise exposure, age, and hereditary predisposition. Other causes
can be drugs toxic to the ears, viral and toxic illness, disturbance
of the fluids in the inner ear of unknown cause, and invasion of
the inner ear by excessive temporal bone growth.
The good news is that individuals who use hearing aids report
significantly higher levels of involvement in social activities,
fewer worries, and more positive social and family experiences.
