2. INTRODUCTION
Hearing aids are the most common
treatment for hearing loss.

3. WHAT ARE HEARING AIDS?
• DEFINITION :
# A hearing aid is a device that can amplify
sound waves in order to help a deaf or
hard-of-hearing person hear sounds more
clearly.
• PURPOSE :
# Recent technology can help most people
with hearing loss understand speech better
and achieve better communication.

4. DO I NEED HEARING AIDS?
If you think you might have hearing loss and could
benefit from a hearing aid, visit your physician, who
may refer you to an otolaryngologist or audiologist.
An otolaryngologist is a physician who
specializes in ear, nose, and throat disorders and will
investigate the cause of the hearing loss.
An audiologist is a hearing health professional
who identifies and measures hearing loss and will
perform a hearing test to assess the type and degree
of loss.

5. HOW DO HEARING AIDS
WORK?
• Hearing aids use the same basic parts to carry
sounds from the environment into your ear and
make them louder. Most hearing aids are digital,
and all are powered with a hearing aid battery.
• Small microphones collect sounds from the
environment. A computer chip with an amplifier
converts the incoming sound into digital code. It
analyse and adjusts the sound based on your
hearing loss, listening needs and the level of the
sounds around you. The amplified signals are
then converted back into sound waves and
delivered to your ears through speakers.

6. WHAT TENHNOLOGY USE
IN HEARING AIDS?
• Analog : Settings and Sound are both processed via
analog technology.
• Digital Programmable : Settings are processed digitally,
Sound is processed via analog technology.
• Full Digital : Both Settings and Sound are processed
digitally.
Opinion: Full Digital is now probably best in most
cases, but not the miracle that some imply. For some
people analog or digital programmables are fine, but
most hearing aids in the future will be full digital.

7. HOW HEARING AIDS
LOOK LIKE?
1. Completely in the canal (CIC) or mini CIC
A completely-in-the-canal hearing aid is molded
to fit inside your ear canal. It improves mild to
moderate hearing loss in adults.
A completely-in-the-canal hearing aid:
• Is the smallest and least visible type
• Is less likely to pick up wind noise
• Uses very small batteries, which have shorter
life and can be difficult to handle
• Doesn't contain extra features, such as volume
control or a directional microphone
• Is susceptible to earwax clogging the speaker

9. HOW HEARING AIDS

2. In the canal (ITC)
An in-the-canal (ITC) hearing aid is custom
molded and fits partly in the ear canal. This
style can improve mild to moderate hearing
loss in adults.
An in-the-canal hearing aid:
• Is less visible in the ear than larger styles
• Includes features that won't fit on
completely-in-the-canal aids, but may be
difficult to adjust due to its small size
• Is susceptible to earwax clogging the
speaker

10. Figure 2 : In the canal (ITC) hearing aid

11. HOW HEARING AIDS

3. In the ear(ITE)
An in-the-ear (ITE) hearing aid is custom made in two
styles — one that fills most of the bowl-shaped area of
your outer ear (full shell) and one that fills only the
lower part (half shell). Both are helpful for people with
mild to severe hearing loss.
An in-the-ear hearing aid:
• Includes features that don't fit on smaller style
hearing aids, such as a volume control
• May be easier to handle
• Uses a larger battery for longer battery life
• Is susceptible to earwax clogging the speaker
• May pick up more wind noise than smaller devices
• Is more visible in the ear than smaller devices

13. HOW HEARING AIDS

4. Behind the ear (BTE)
A behind-the-ear (BTE) hearing aid hooks over the top
of your ear and rests behind the ear. A tube connects
the hearing aid to a custom earpiece called an
earmold that fits in your ear canal. This type is
appropriate for people of all ages and those with
almost any type of hearing loss.
A behind-the-ear hearing aid:
• Traditionally has been the largest type of hearing
aid, though some newer mini designs are
streamlined and barely visible
• Is capable of more amplification than are other
styles
• May pick up more wind noise than other styles

5. Receiver in canal (RIC) or receiver in the ear
(RITE)
The receiver-in-canal (RIC) and receiver-in-the-
ear (RITE) styles are similar to a behind-the-
ear hearing aid with the speaker or receiver in
the canal or in the ear. A tiny wire, rather than
tubing, connects the pieces.
A receiver-in-canal hearing aid:
• Has a less visible behind-the-ear portion
• Is susceptible to earwax clogging the
speaker

17. HOW HEARING AIDS
LOOK LIKE?
6. Open fit hearing aid
An open-fit hearing aid is a variation of the behind-the-ear
hearing aid with a thin tube. This style keeps the ear
canal very open, allowing for low-frequency sounds to
enter the ear naturally and for high-frequency sounds to
be amplified through the hearing aid. This makes the
style a good choice for people with mild to moderate
hearing loss.
An open-fit hearing aid:
• Is less visible
• Doesn't plug the ear like the small in-the-canal hearing
aids do, making your own voice sound better to you
• May be more difficult to handle and adjust due to small
parts

19. THE USES OF HEARING AID
Hearing aids are an acoustic electric tool that can be
used by people with impaired hearing in one ear.
Usually these tools can be installed on the inside or
on the human ear around the ears. Hearing aids are
made to strengthen the stimulation of the sensory
cells of the inner ear are damaged to boost the voice
and the sounds from outside. The hearing aid is an
electronic device that uses the battery in its
application where there is a microphone that
converts sound waves from these into electrical
energy which is then received by an amplifier that
can increase the volume on the speakers and sends
it to exist in the inner ear.

20. • MIC or microphone It is a component of the type of transducer that can convert
energy - energy acoustic or sound waves into an electrical signal.
• Amplifier has a function to process the electrical signals or sound waves generated by
the MIC to further electrical signals or sound waves can be enlarged and completed
further magnified signal is processed by the Receiver.
• The receiver itself has functions for converting an electric signal or sound waves into a
sound that has been hardened. The receiver can be analogized as well as the speakers.
• The battery has a function to be flowing electricity in order to carry out the above
components, namely MIC, Amplifier and Receiver. Read: How To Use Hearing Aids For
Maximum Results

21. THE ADVANTAGES OF
HEARING AID
• The battery is large, so that it can be long lasting.
• There is a FM cable connection and another adapter.
• Hidden from visually that will make the user more comfortable.
• It is harder for hearing aid.
• It is high-pitched.
• The frequency response is finer.
• The earmould can be adjusted with the order or directly with
the user.
• It is stick rigidly.
• The position placement of microphone and receiver are very
good.

22. THE DISADVANTAGES OF HEARING
AIDHigh Price
-Hearing aids can be costly, with a top-of-the-line brand new
model. some would argue that a couple thousand is a nominal
price to pay when you consider how much you can improve your
quality of life by having your hearing restored to comfortable
levels
Potential Discomfort
-If you choose the wrong configuration type or style,
or the custom mould is not fitted properly, you could
encounter some discomfort.
Maintenance Issues
-Keep in mind that you may have to perform
maintenance on your hearing aids from time to time.
This may include removing any built up ear wax from
the casing.

23. IMPACT HEARING AIDS FROM
THE REAL STUDY
• can help the deaf to hear more clearly
• will give confidence to the people who wear
hearing aids
• can make them perfect in the eyes of everyone
by having all faculty
• allowing them to find their own advantage
• give them a chance to grow up like other
children
• can help them in school learning system

24. Range ages for this problems. This problem
occurs for all ages regardless of newborns,
children and old people. It is proved in one ear
problems and hearing surveys conducted by
the Ministry of Health in 2003-2004, which
indicates a number of children (under 18)
were found to have hearing problems,
although the amount is not as high as adult.
