ABOUT HEARING
LOSS
Life is enriched by the experiences
we have through our five senses: sight, touch, smell, taste,
and hearing. Our senses work together and enable us to learn
and enjoy life. Hearing is especially vital; it enables us to
communicate our wants, needs and emotions.
Unfortunately, many people
suffering from a hearing loss are either unaware of their condition
or are too embarrassed to seek help. You can't reverse hearing
loss. However your professional at Gateway Hearing Center can
apply the appropriate care and technology to lessen its effects, and
improve the quality of sounds you hear.
Gradual hearing loss is a common
condition and often occurs as a result of years of chronic exposure
to loud noise. Other causes include illness, ototoxic
medications, earwax blockage, heredity and the natural aging
process. In the United States, approximately one-third of
individuals over 60 years of age, and one-half of those over 85, has
some degree of hearing loss.
You can't reverse hearing loss.
However, your hearing healthcare professional at Gateway Hearing
Center can apply the appropriate care and technology to lessen their
effects and improve the quality of sounds you hear.
Unfortunately, many people suffering from a hearing loss are either
unaware or ashamed of their condition, and therefore, do not utilize
the advanced technology that is available.

High-Frequency Hearing Loss
In the first stages of hearing impairment, the high frequencies are
usually lost first. Therefore, difficulty hearing or
understanding high pitched voices of women and children is one of
the first symptoms. It is important to recognize that hearing
someone and understanding them are two different things.
High-frequency hearing loss distorts sound, which makes speech
difficult to understand even if it can be heard.
People with hearing loss often have
difficulty differentiating words that sound alike, especially words
that contain S, F, SH, CH, H, TH, T, K or soft C sounds. These
consonants are in a much higher frequency range than vowels and
other consonants.
Degree of Hearing Loss
There are five levels or degrees of hearing loss. A person
with normal hearing can perceive very soft sounds, whereas a person
with a profound loss can only perceive sounds louder than 90 dB.
| Type
of Hearing Loss |
Lowest
Intensity
of Sound Heard |
| Normal
range (or no impairment) |
0
dB to 20 dB |
| Mild
Loss |
21
dB to 40 dB |
| Moderate
Loss |
41
dB to 60 dB |
| Severe
Loss |
61
dB to 85 dB |
| Profound
Loss |
91
dB or more |
Prevention
Avoiding loud noise may help prevent premature hearing loss and the
perception of sound lacking clarity. There are easy ways to
identify if a particular sound is potentially harmful.
- Do you have difficulty talking
or hearing others talk over the sound?
- Does the sound make your ears
hurt?
- Do your ears ring after the
sound?
- Do other sounds seem muffled
after exposure?
If you answered "yes" to
any of the above questions, the noise may be damaging your hearing.
Most people don't realize how loud everyday sounds actually are.
Sounds above 85 dB are harmful depending on how long and how often
you are exposed to them. The louder a sound is, the lower the
amount of exposure is required to cause damage. If used
properly, hearing protection devices can reduce the loudness of
sound reaching the ears.
Are you experiencing any of these
symptoms?
- Does speech sound muffled?
- Do you have a hard time hearing
on the telephone?
- Is it difficult to understand
words, especially against background noise or in a crowd of
people?
- Do you frequently ask others to
speak more slowly, clearly and loudly?
- Do you turn up the volume of the
television or radio more than others?
- Do you avoid engaging in
conversation?
- Do you avoid certain social
settings?
- Do you feel embarrassed,
frustrated or tired due to these symptoms?
Defining Sound
Sound is measured by intensity and pitch. Intensity is the
loudness of sound, which is measured in decibels. Pitch is
measured in frequency of sound vibrations per second. A deep
voice has a low pitch and frequency, whereas, a child's voice has a
high pitch and frequency.
The table below identifies decibel
levels for common noises. How long and often have you been
exposed to dB 85 and above?

Nearly 30 million Americans will be
exposed to dangerous noise levels today. With 10 million
Americans suffering from irreversible hearing damage due to noise,
it is never too early to start actively protecting your
hearing. Remove yourself from loud settings. Turn down
the radio and television. Wear earplugs if you cannot avoid
loud environments. Start today.

professional at Gateway Hearing Center about the prevention and
