Hearing aids are electronic devices that amplify sound to help people with hearing loss. There are two main types - analog hearing aids amplify all sounds equally while digital hearing aids analyze sound and amplify different frequencies individually for clearer sound. Digital hearing aids break sound into 48 or more frequency bands and amplify each band as needed. Hearing aids come in several styles including custom-fit models that go completely in the ear canal or invisible models. Behind-the-ear models have the components behind the ear connected to an earpiece. Receiver-in-canal models place the microphone in the outer ear connected by a tube to a receiver in the ear canal.

aid people who have a hearing problems

3. How a hearing aid works
• A microphone picks up sounds.
• Sounds are analyzed by the processing chip.
• Processed sounds are sent to the amplifier.
• Amplified sounds are sent to the loudspeaker.
• Sounds are transmitted by the loudspeaker into the inner
ear where they are transformed into electrical impulses.
• Impulses are picked up by the brain where they are
processed.

4. Difference between analog and digital hearing aids
• Analog hearing aids make continuous sound waves louder.
These hearing aids essentially amplify all sounds (e.g.,
speech and noise) in the same way. Analog hearing aids are
becoming less and less common.
• Digital hearing aids have all the features of analog hearing
aids, but they convert sound waves into digital signals and
produce an exact duplication of sound. Digital hearing aids
analyze speech and other environmental sounds.

5. How digital hearing aids work
Unlike analog aids, in digital hearing aids, sound enters the
device is broken into multiple frequency bands. Each band is
then amplified by the amount necessary to return the wearer's
hearing to normal levels at that band.
With digital technology, devices can now break sound into as
many as 48 different bands. This feature makes the sound
quality provided of a digital hearing aids far better than the
analogue technologies.

6. Hearing Aid Models
• Hearing aids are available in an extensive range of colors
and sizes. Below chart shows some of the more common
hearing aid models available.

7. Hearing Aid Categories
Since hearing loss problems differ with people to people, there
are many different models and styles of hearing devices are
there to choose from.
Generally Hearing aids can be placed in three categories.
• Custom in-the-ear models (ITE)
• Behind-the-ear (BTE)
• Receiver in the ear (RITE)

8. Custom in-the-ear models
Custom in-the-ear models are custom made to fit the contours
of your ear canal.
• Full shell
• Half shell Canal
• Mini canal
• Completely in the canal (CIC)
• Invisible in the Canal (IIC)
Depending on the specific type, it may be more or less
invisible in your ear.

9. Behind-the-Ear models (BTE)
In this type, case of this hearing aid is hidden behind your ear
and connected to a molded receiver that fits snugly in the
outer ear. These hearing aids offer a volume control and/or
push button that allow selection from multiple programs for
specific performance situations.

10. Receiver-in-Canal
This model combines the advantages of both the behind-the-ear
and custom (in-the-ear) models. The microphone has
been moved to the outer ear and is connected to the main
body of the hearing aid by a thin transparent tube.
The result is a virtually invisible hearing instrument that offers
Open-fitting comfort and maximum wind noise suppression.
