HEARING :
Hearing refers to the reception of sound by
the ear, its analysis, and its transmission to
the brain.
IMPAIRMENT:
An impairment is any loss or abnormality of
psychological, physiological or anatomical
structure or function.
TYPES OF
HEARING
IMPAIRMENT
TYPES OF HEARING IMPAIRMENT
• Conductive
• Sensorineural
hearing loss
• Mixed hearing
loss
CONDUCTIVE HEARING
IMPAIRMENT:
• A conductive loss refers to
a decrease in sound
caused by a problem in the
outer or middle ear.
Sensorineural
Hearing
Loss
SENSORINEURAL HEARING IMPAIRMENT:
• A sensorineural loss refers
to a problem located in the
inner ear or along the nerve
pathway between the inner
ear and the brain.
MIXED HEARING IMPAIRMENT:
• A mixed loss refers
to a conductive loss
and a sensorineural
loss occurring at the
same time.
AGE OF HEARING IMPAIRMENT:
Pre lingual :is the loss of
hearing before speech and
language developed
Post lingual: is loss of hearing
after spontaneous speech and
language has developed.
DEGREE
AND TYPES
OF HEARING
IMPAIRMENT
HOW HEARING IMPAIRMENT
OCCURS
Causes:Hearing impairment includes:
a) A gradual buildup of earwax.
b)Ear infection and abnormal bone growths or tumors.
c)Ruptured eardrum.
d)Damage to the inner ear.
SYMPTOMS• Muffling of speech and other
sounds.
• Difficulty understanding words,
especially against background noise
or in a crowd of people.
• Frequently asking others to speak
more slowly, clearly and loudly.
• Needing to turn up the volume of the
television or radio.
• Withdrawal from conversations.
• Avoidance of some social settings.
RISK
FACTORS IN
HEARING
LOSS
RISK FACTORS:
• Aging.
• Heredity.
• Occupational noises.
• Some medications.
• Some illness,
PSYCHOLOGICAL EFFECTS
• Depression
• Anxiety
• An often false sense that others are
angry with you.
• Shame, guilt and anger.
• Lack of concentration.
• Worry and frustration.
• Insecurity.
• Embarrassment

PSYCHOLOGICAL EFFECTS:
COPING AND SUPPORT:
These tips can help you to communicate
more easily despite your hearing loss.
• Position yourself to hear:
Face the person with whom you're having
a conversation.
• Turn off background noise:
For example, noise from a television may
interfere with conversation.
• Ask others to speak clearly:
Most people will be helpful if they know you're having trouble hearing them.
• Choose quiet settings: In public,
such as in a restaurant or at a
social gathering, choose a place
to talk that's away from noisy
areas.
• Consider using an assistive
listening device: Hearing
devices, such as TV-listening
systems or telephone-amplifying
devices, can help you hear better
while decreasing other noises
around you.
BENEFITS OF TREATMENT
• Greater self-confidence
• Closer relationships with loved ones
• Improved outlook on life
PREVENTION FOR HEARING
IMPAIRMENT
Protect your ears in the workplace:
• Specially designed earmuffs that resemble earphones can protect your ears by bringing most loud sounds down to an acceptable level. Foam, pre-formed, or custom-molded earplugs made of plastic or rubber also can effectively protect your ears from damaging noise.
Have your hearing tested:
. Consider regular hearing
tests if you work in a noisy
environment. Regular testing
of your ears can provide
early detection of hearing
loss. Knowing you've lost
some hearing means you're
in a position to take steps to
prevent further hearing loss.
Avoid recreational risks:• Some activities, hunting and
listening to extremely loud
music for long periods of time,
can damage your hearing.
• Wearing hearing protectors or
taking breaks from the noise
during loud recreational
activities can protect your
ears.
• Turning down the volume
when listening to music can
help you avoid damage to
your hearing.
TEST AND DIAGNOSIS
GENERAL SCREENING TEST:
• Doctor may ask to cover
one ear at a time to see
how well hear words
spoken at various
volumes and you
respond to other
sounds.
TUNING FORK :• Tuning forks are two-pronged,
metal instruments that produce
sounds when struck.
• A tuning fork evaluation may
reveal whether hearing loss
caused by damage to the
vibrating part of middle ear,
damage to sensors or nerve of
inner ear or both.
AUDIOMETRY TEST• Test conducted by an
audiologist, you wear earphones
and hear sounds directed to one
ear at a time. The audiologist
presents a range of sounds of
various tones and asks you to
indicate each time you hear the
sound.
• The audiologist will also present
various words to determine your
hearing ability,
TREATMENTS:
Treatment depends on the cause and severity of your
hearing loss.
Options include:
• Removing wax blockage.
• Hearing aids.
• Cochlear implants.
REMOVING WAX BLOCKAGE:
Cleaning the outside of the
ear by wiping with a cloth.
• Putting cerumenolytic
solutions (solutions to
dissolve wax) into the ear
canal.
• Irrigating or syringing the
ear.
• Removing the wax manually
using special instruments.
HEARING AIDS:A hearing aid is a small
electronic device that you
wear in or behind your ear.
It makes some sounds
louder. A hearing aid can
help people hear more in
both quiet and noisy
situations.
Hearing aid parts:
• Microphone: detects the
sound.
• Amplifier: make the
sound stronger.
• Battery: provides power
to the electronic parts
• Volume control:
increases or decreases
the volume of the sound.
