What are hearing aids?
Hearing aids are instruments that amplify sound for people
who cannot hear well. They have a microphone to pick up
sound, an amplifier to increase the sound, an ear piece to
transmit the sound to the ear, and a battery for power.
These separate parts are most often packaged together in
small in-the-ear hearing aids. People have difficulty with
different areas of hearing and require different levels of
sound amplification.
Selecting a hearing aid
There are different styles of hearing aids. Be careful to
select a hearing aid that meets your specific needs.
- A body aid has an earpiece connected by a wire to a small
case containing a microphone and amplifier. The case is
worn on the body. Body aids are the most powerful type
of hearing aid.
- A behind-the-ear hearing aid has an earpiece that
connects to a short tube, microphone, and amplifier.
- An in-the-ear hearing aid uses an earpiece that
contains a microphone and amplifier and sits inside the
user's ear. About 80% of hearing aid users wear this style.
- An in-the-canal hearing aid is similar to an in-the-ear
hearing aid, but is smaller and sits deeper in the ear.
- A completely-in-the-canal hearing aid is smaller still,
out of sight, and deep inside the ear canal.
- Eyeglass hearing aids have the hearing aid in the
eyeglass frames.
Be sure to look at different hearing aids before you make
your choice. Don't forget the importance of warranty,
maintenance, and repairs. If possible, take advantage of a
free trial period to be sure the aid you choose is right for
you. The most expensive hearing aid may not be your best
choice.
Getting used to your hearing aid
Once you have found the hearing aid that meets your needs,
you will soon get used to wearing it and learn to adjust the
controls to pick up sound in different situations. Today's
hearing aids are able to screen out a lot of background
noise. They are small, easy to wear, and can make a great
difference in your life.
How can I help my hearing aid to help me?
Even with a hearing aid, there are several strategies you
will find helpful to make communication easier. Don't be
shy. Tell people you have a hearing problem and politely
ask them to face you and speak clearly so that you can hear
better. Watch lips and watch body signs. If you don't
catch what was said, ask the person to repeat it, or ask,
"Did you say ....?"
In groups or in an audience, try to position yourself where
you can see the speaker. Don't be afraid to ask a speaker
to speak up or use a microphone. If you are in a crowd and
can't hear someone speak because of background noise,
suggest you both move to the edge of the crowd where the
competing noise is less.
What other hearing assistance devices might I use?
Amplified telephone receivers and amplified headsets for
listening to music or watching television can be very
helpful. You can also install a flashing light system in
your home instead of a ringing telephone or doorbell. Many
churches and auditoriums have special headphones installed
for people with hearing problems. Take advantage of them.
