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

LOSS

RISK FACTORS:

such as in a restaurant or at a

social gathering, choose a place

to talk that's away from noisy

listening device: Hearing

devices, such as TV-listening

systems or telephone-amplifying

devices, can help you hear better

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.
