The purpose of an audiological evaluation is to determine hearing acuity.
If hearing loss is identified, it is categorized by the type, the degree
and the configuration of the loss.
Type
The type of hearing loss suggests the point in the auditory system where
the loss is occurring.
Conductive: Temporary or permanent loss typically due to abnormal conditions
of the outer and/or middle ear, such as earwax, infection or abnormal
bone growth in the middle ear. May be medically or surgically treated
by an ear, nose and throat physician or primary care provider.
Sensorineural: Typically a permanent hearing loss affecting the nerve cells
in the cochlea and/or auditory nerve, which may be due to disease, the
aging process, noise exposure, trauma or inherited conditions. Typically
not medically or surgically treated.
Mixed: Combination of both conductive and sensorineural.
Degree
The degree categorizes the severity of the hearing loss.
Normal: Hearing is within normal limits, suggesting no hearing loss.
Mild: Minimal hearing loss; the individual will miss some consonants and vowels.
Moderate: Individual may understand face-to-face conversation in a quiet
situation; can miss 50-75 percent of spoken language in the presence of
background noise.
Moderately severe: Individual will miss most of all spoken message, even
talking face-to-face.
Severe: Individual may not hear voice, unless speech is very loud.
Profound: Individual may not be able to detect the presence of speech or
even loud environmental sounds.
Configuration
Configuration attributes:
Bilateral versus unilateral hearing loss
Symmetrical versus asymmetrical hearing loss
High frequency versus low-frequency hearing loss
Flat versus sloping hearing loss
Progressive versus sudden hearing loss
Stable versus fluctuating hearing loss
Depending on results, the audiologist may recommend amplification and/or
possibly refer you to an
Ear, Nose and Throat specialist.
Why is it Important to Treat Hearing Loss?
Relationships: relationships rely on good communication; hearing loss can hinder the potential
for responsiveness.
Earnings: hearing is critical to meeting one’s full potential at work; studies
show that the risk of income loss can be reduced by using hearing aids.
Cognitive skills: studies show that seniors with hearing loss are more prone to dementia,
but by using hearing aids, they likely can improve their cognitive skills.
Happiness: hearing loss can make people feel frustrated and alone. Restoring the
ability to engage socially and live confidently boosts the quality of life.
Self-confidence: using hearing aids to bring back the gift of sound can improve one’s
sense of control and self-confidence.
Are You At Risk?
Groups at risk for hearing loss include:
History of noise exposure
Family history of hearing loss
Natural decrease of hearing due to the aging process
Chemotherapy and/or radiation treatments
Signs and Symptoms
Complaints of muffled speech or that “everybody mumbles”
Difficulty understanding words against background noise or in a crowd of people
Turning the television or radio louder than other people would like
Difficulty hearing women or children
Asking for several repetitions – saying “what?” often
Straining to hear or follow conversations
Withdrawal from conversations due to difficulty understanding
Difficulty hearing on the telephone
