Hearing Loss: More Prevalent than
You Think
Hearing loss is the third most
common health problem in the U.S., and losing your hearing rarely occurs
suddenly, but it is particularly challenging because it can limit the simplest
interactions between family, friends and general acquaintances, jeopardize your
personal safety, and makes day-to-day living difficult. Since hearing loss
usually develops over a long period of time, it is almost undetectable at first
because your brain can compensate for your hearing difficulties for a long
period of time. However, after so long the brain can no longer compensate for
hearing loss.
Unfortunately, even once some
individuals realize they have hearing loss, they do nothing about it. Simply
put, being aware of your hearing loss is one thing, but acknowledging it might
not be so easy. The problem is that if you wait too long, you risk serious
consequences. Researchers have found that after about seven years, our brains
simply lose the ability to understand certain sounds. If you wait too long to
get help, even though you might be able to hear the sounds that you couldn't
previously hear, your brain may not be able to correctly interpret what is
being heard.
How Widespread is Hearing Loss?
To grasp how widespread hearing loss
is, consider these statistics:
• Worldwide, 1 of 6 individuals has
a hearing loss.
• One of every five individuals in
the U.S. over the age of 12 has hearing loss.
• Almost 15% of school-age children
(ages 6-19) have some degree of hearing loss.
• An estimated 50 million people in
the U.S. experience tinnitus. 90% of those individuals have hearing loss.
• Hearing loss is the third most
prevalent health issue in older adults after arthritis and heart disease.
• Hearing loss is the #1 disability
for our returning veterans.
Are There Different Types of Hearing
Loss?
Hearing
loss is diagnosed based on the person's history, behavior, and the results of
an audiological examination. To understand how your hearing loss occurred,
you must first understand how you hear. Hearing loss is defined as one of three
types:
● Conductive
(involves outer or middle ear)
● Sensorineural
(involves inner ear)
● Mixed
(combination of the two)
Your
ear consists of three major areas: outer ear, middle ear and inner ear. Sound
waves pass through the outer ear and cause vibrations at the eardrum. The
eardrum and three small bones of the middle ear amplify the vibrations as they
travel to the inner ear. There, the vibrations pass through fluid in a
snail-shaped structure in the inner ear (cochlea). Attached to nerve cells in
the cochlea are thousands of tiny hairs that help translate sound vibrations
into electrical signals that are transmitted to your brain. Your brain turns
these signals into sound.
What Causes Hearing Loss?
Hearing
loss can be cause by several factors, such as:
● Damage to the inner ear. Aging and exposure to loud noise may cause
wear and tear on the hairs or nerve cells in the cochlea that send sound
signals to the brain. When these hairs or nerve cells are damaged or missing,
electrical signals aren't transmitted as efficiently, and hearing loss occurs.
Higher pitched tones may become muffled, and it may become difficult for you to
pick out words against background noise.
● Gradual buildup of earwax. Earwax can block the ear canal
and prevent conduction of sound waves. Earwax removal can help restore your
hearing.
● Ear infection and abnormal bone
growths or tumors. In
the outer or middle ear, any of these can cause hearing loss.
● Ruptured eardrum (tympanic membrane
perforation). Loud
blasts of noise, sudden changes in pressure, poking your eardrum with an object
and infection can cause your eardrum to rupture and affect your hearing.
Am I at Risk of Losing My Hearing?
Factors
that may damage or lead to loss of the hairs and nerve cells in your inner ear
include:
● Heredity. Your genetic makeup may make
you more susceptible to ear damage from sound or deterioration from aging.
● Loud noise. Exposure to loud sounds can
damage the cells of your inner ear. Damage can occur with long-term exposure to
loud noises, or from a short blast of noise, such as from a gunshot.
● Recreational noises. Exposure to explosive noises,
such as from firearms and jet engines, can cause immediate, permanent hearing
loss. Other recreational activities with dangerously high noise levels include
snowmobiling, motorcycling, carpentry or listening to loud music.
● Occupational noises. Jobs where loud noise is a
regular part of the working environment, such as farming, construction or
factory work, can lead to damage inside your ear.
● Some medications. Drugs such as the antibiotic
gentamicin, sildenafil (Viagra) and certain chemotherapy drugs, can damage the
inner ear. Temporary effects on your hearing — ringing in the ear (tinnitus) or
hearing loss — can occur if you take very high doses of aspirin, other pain
relievers, antimalarial drugs or loop diuretics.
● Some illnesses. Diseases or illnesses that
result in high fever, such as meningitis, may damage the cochlea.
● Aging. Age-related hearing loss (presbycusis) is a natural
process that usually starts between the ages of 45 and 65 and can be worsened
by external factors such as high noise levels. Age-related hearing loss mainly
affects the higher frequencies, and usually occurs in both ears. It is caused
by damage to the fine hair sensory receptor cells in the cochlea. This leads to
diminished signal transmission to the auditory nerve. The first signs can be
the loss of soft sounds such as the rustling of leaves or hearing your blinker
in the car. Difficulty understanding speech in high background noise is also
common. Because age-related hearing loss occurs gradually, people often only
become aware of it as it progresses.
Can I Prevent Hearing Loss or Losing
Any More of my Hearing?
Unfortunately,
you can't reverse most types of hearing loss. However, you and your doctor or a
hearing specialist can take steps to improve what you hear. The following steps
can help you prevent noise-induced hearing loss and avoid worsening of age-related
hearing loss:
● Protect your ears. Limiting the duration and
intensity of your exposure to noise is the best protection. In the workplace,
plastic earplugs or glycerin-filled earmuffs can help protect your ears from
damaging noise.
● Have your hearing tested. Consider regular hearing tests
if you work in a noisy environment. If you've lost some hearing, you can take
steps to prevent further loss.
● Avoid recreational risks. Activities such as riding a
snowmobile, hunting, using power tools or listening to rock concerts can damage
your hearing over time. Wearing hearing protectors or taking breaks from the
noise can protect your ears. Turning down the music volume is helpful too.
What Should I Do If I Think I have Hearing Loss?
If you experience the warning signs
listed below repeatedly, or in combination, they may indicate a hearing loss.
If you do find yourself in one or more of the below listed categories, realize
you are not alone. Contact the Atlanta Institute for ENT to schedule a comprehensive
hearing examination with one of our ear, nose, and throat specialists (ENT or
Otolaryngologist) to find out if you are one of the growing number of hearing
