Hearing Aids for Adults
Roughly 20% of all people who need hearing aids actually get
them. Most people don't realize that most hearing losses can
be treated with hearing aids. Most people also don't realize
that untreated hearing loss causes embarrassment, social stress,
tension, and fatigue not only for the person with the hearing
loss but also for family members, friends and work
associates.
Successful hearing aid users are those who are motivated to
improve their communication by improving their listening and
hearing. They have worked with their audiologist to learn what
they can expect from hearing aids - that is, understanding what a
hearing aid can and cannot do. They also have family support.
How can family, friends, and co-workers be affected by MY
hearing loss?
Family, friends, and people at work are just as bothered by your
hearing loss as you are.
Talking take extra effort. They may be impatient because they
have to repeat what they say to you so often. Conversations with
you become time consuming.
They can't communicate with you by phone the way they used
to.
You miss out on whispered affections. They feel at a loss to
help, and they often wish for the "old relationship"
they remember.
This is where you can take the lead and consult an audiologist
to see what can be done to improve your hearing and to improve
communication at home, at work, and in your social and leisure
time activity.
Find an audiologist near you who is certified by the American
Speech-Language-Hearing Association.
What are the first steps in considering hearing aids?
First you should have a good understanding of your hearing loss.
What kind of hearing loss do you have? Is it permanent? What does
your audiogram say about what sounds you can and cannot hear?
Once you understand your audiogram, you can begin to understand
why it is you have trouble hearing in different situations.
What can I expect the audiologist to do in selecting a hearing
aid for me?
Assuming that the audiologic evaluation has been completed and
you have had an opportunity to ask questions about your hearing
loss, the audiologist will talk with you about your ability to
use hearing aids.
Your audiologist will want to find out about your typical
communication activities: at home with family, at work, in your
social activities, and in your leisure time activities. You are a
very important partner in this discussion. Your answers will help
to decide the type and style of hearing aid that is best for you.
Your answers will also help in deciding what hearing aid features
you need.
In thinking about communication at home, the audiologist may
ask:
- Do you live alone? With another person? With children?
- What is your current living situation? A dormitory? An
apartment? A house? A facility such as a group home, assisted
living, or nursing home?
- Do you watch television?
- Do you spend a lot of time on the phone?
- Are there certain people that are more difficult to hear
than others?
- Do you have to communicate from upstairs to downstairs, or
across many rooms?
- Do you have difficulty detecting the doorbell? The phone
ringing? The microwave buzzer? The baby crying?
- Do you have conditions such as reduced vision? Arthritis?
Other conditions that might affect your ability to manipulate
hearing aid controls and batteries?
In thinking about communication at work, in career training,
or in school or college environments the audiologist may ask:
- Where do you work? Construction? Sales? Office?
School?
- What is your work environment like? Outside? Noisy? Large
office? Quiet, small office? In a vehicle?
- What level of interaction with people does your job
require?
- What level of telephone use does your job require? What
kind of telephone? Cell phone? Wired phone? Speakerphone?
- Do you deal with voice messages? Taking dictation via phone
or recorder?
- Do you have to attend meetings? Lectures? Seminars?
- Do you give presentations or run meetings?
- Are there situations or communication with certain people
that are particularly difficult?
- Does your employer know about the Americans with
Disabilities Act responsibilities for reasonable
accommodations? (For example, phone amplifiers or assistive
devices for meetings).
In thinking about your social and leisure activities:
- Are your social activities more one-to-one or larger group
activities?
- Do you attend lectures, concerts, theater?
- Have you ever used an assistive listening device in a
public setting?
- Do you go to movies? Dinner parties? Restaurants?
- Do your leisure activities involve sporting events?
Machinery? Fishing? Bird-watching?
- Are there activities you now avoid because you can' t
hear well?
Once you and your audiologist have talked about your listening
needs, the audiologist will have a better idea of what hearing
aid will best accommodate your hearing loss in your
personal situation. The audiologist will take into account your
hearing loss, your communication needs, and your budget in
selecting your hearing aids.
Once I get my hearing aid(s) what happens?
The audiologist will explain how your hearing aid(s) works.
Information that should be covered includes:
- inserting and removing your hearing aids
- operating the switches (on/off, telephone switch)
- using audio-input (if part of your hearing aid)
- replacing batteries
- caring for your hearing aid
- cleaning any earmold
- using your aid with assistive listenng devices
- expectations for hearing in different listening
situations
- troubleshooting problems.
Again, it is important that you attend and participate in this
hearing aid orientation.
Examples of common questions that you should be sure to have
answered are:
- How tight should my earmold be?
- How do I put my hearing aid in my ear?
- How do I remove my hearing aid? Should I turn it off before
I remove it?
- What if I drop my hearing aid?
- Where should I store my hearing aid? Should I take the
battery out?
- Where do I get batteries?
- How often should batteries be replaced? How long do they
last?
- What do I do with old batteries? Are batteries harmful if
swallowed?
- What are signs that I need to contact my audiologist?
- Should I wash my hearing aid? How do I clean it? What do I
do when earwax plugs up the hearing aid?
- How do I clean my earmold?
- What is the whistling sound I sometimes hear? What do I do
about it?
- How often should the earmold or tubing be replaced?
- What if I lose my hearing aid? What if it goes through the
laundry? Or is chewed by a pet dog or cat?
- Should I get insurance for my hearing aids?
- What is an assistive listening device? Isn' t my
hearing aid enough?
Many audiologists offer group classes on adjusting to your new
hearing aid. This is an opportunity for you to meet in a group
with new hearing aid users and learn how to make optimum use of
your hearing aids. Sometimes experienced hearing aid users
participate in classes and share useful hints about managing
hearing aids.
Other Assistive Technology
Hearing aids are very helpful in one-on-one situations, but
sometimes they are not enough. In fact, many hearing aid users
ask, "Why do I need additional assistive technology devices?
I thought that was what the hearing aid was for."
There are three situations that are difficult for all
listeners, but especially difficult for people with hearing loss
and people using hearing aids:
-
Distance between the listener and the sound
source
The farther away you are from a speaker, the harder it is to
hear the speaker! This is pretty self-evident! The intensity,
or loudness, of a sound fades repidly as it travels over
distance. In fact, for every doubling of distance, the
sound's intensity decreases by 6 dB. For example, an 80dB
speaking voice three inches away will be reduced to 50 dB 8
feet away. This fact explains why you may have no difficulty
hearing someone in close range, but considerable difficulty
hearing the same person across the room.
-
Competing noise in the environment
Most rooms have significant levels of background noise that
compete with the spoken message or sound we want to hear.
Examples of background noise are ventilation systems, others
talking, paper shuffling, computers, radios, TVs operating,
food preparation going on, outside traffic or construction,
activities going on in adjacent rooms, etc. These sounds,
combined with the lower volume of speech reaching your ear due
to the distance factors described above, make hearing in noisy
backgrounds very challenging. For optimum hearing, speech
should be at least 20-25 dB louder than the competing
noise.
-
Poor room acoustics.
Room acoustics is another factor that plays a role in your
ability to hear. Sound waves bouncing off hard surfaces like
windows, walls, and hard floors create sound reflections and
echoes (reverberation) that "smear" and distort
speech. For example, large gyms, cathedrals, marble lobbies,
etc. quickly come to mind when we think about reverberation.
(Reverberation occurs, too, in classrooms, indoor sports
courts, etc.). We' ve all experienced how much easier it is
to hear in rooms that are carpeted than in rooms with tile or
cement floors.
Any one of these three conditions (distance, noise, and
reverberation) is problematic, but more often than not, they
occur together and have a debilitating effect on your ability to
hear and process speech.
