Most
children hear and listen from birth. They learn to talk by imitating the
sounds around them and the voices of their parents and caregivers. But
that's not true for all children.
2 or 3 out of every 1,000 children in the United States are born
deaf or hard-of-hearing.
More lose their hearing later during childhood.
Many of these children may need to learn speech and language differently,
so it's important to detect deafness or hearing loss as early as possible.
Your baby should have a hearing screening within the first month of
life.
If hearing loss is suspected, make sure a hearing expert, called an
audiologist (aw-dee-AH-luh-jist) tests your baby's hearing by 3 months
of age. If hearing loss is confirmed, it's important to consider the
use of hearing devices and other communication options by 6 months of
age.
Many hospitals automatically screen all newborns for hearing loss. Some
screen only those newborns at high risk for hearing loss, such as babies
with a family history of deafness or hearing problems, low birth weight,
or certain other medical conditions. Even if your baby doesn't have risk
factors, being screened is important, because many children with no risk
factors have hearing loss. Even children whose parents and grandparents
hear normally may be born with a hearing loss. Find out what your
hospital does. If you and your baby are already home and you don't know
if your baby's hearing was tested, ask the doctor or the clinic where
your baby's records are.
Recently, many States have passed Early Hearing Detection and Intervention
legislation. A few other States regularly screen the hearing of most
newborns, but have no legislation that requires screening. To find out
what your State does, visit the American
Speech-Language-Hearing Association (ASHA).
Hearing tests that are used to screen babies:
Otoacoustic emissions (OAE) tests can show whether parts of the
ear respond properly to sound. During this test, a sponge earphone is
placed into the ear canal. The ear is stimulated with sound, and the
"echo" is measured. The echo is found in everyone who hears
normally. If there is no echo, it could indicate a hearing loss.
Auditory brain stem response (ABR) tests check how the brain
stem (the part of the nerve that carries sound from the ear to the brain)
and the brain respond to sound. During this test, your child wears earphones,
and electrodes are placed on the head and ears. A mild sedative may
be given to help keep your child calm and quiet during the test. The
nurse or doctor sends sounds through the earphones and measures the
electrical activity in your child's brain when he or she should be hearing.
In both tests, no activity is required from your child other than lying
still.
If your child doesn't respond consistently to the sounds presented
during either of these tests, your doctor may suggest a follow up hearing
screening and a referral to an audiologist for a more comprehensive hearing
evaluation.
The most important time for a child to be exposed to and
learn language is in the first 3 years of life. In fact, children
begin learning speech and language in the first 6 months of life. Research
suggests that those who have hearing impairment and get intervention have
better language skills than those who don't. The earlier you know about
deafness or hearing loss, the sooner you can make sure your child benefits
from strategies that will help him or her learn to communicate.
Assistive devices and strategies for children who are hard-of-hearing:
Hearing aids are instruments that make sounds louder. They are
worn in or behind the ear and come in several different shapes and sizes.
Hearing aids can be used for varying degrees of hearing loss, moderate
or severe. An audiologist will fit a hearing aid that will work best
for your child's hearing loss. Hearing aids can be expensive, so you'll
want to find out whether they have a warranty or trial period. You'll
also want to talk with your insurance provider to understand what is
covered and what isn't.
Cochlear (COKE-lee-ur) implants have three parts: a headpiece,
a speech processor, and a receiver. The headpiece is worn just behind
the ear where it picks up sound and sends it to the speech processor.
The speech processor, a beeper-sized device that can fit in a pocket
or on a belt, converts the sound into a special signal that is sent
to the receiver. The receiver, a small round disc about the size of
a quarter that a surgeon has placed under the skin behind one ear, sends
a sound signal to the brain.
An audiologist can help you to determine whether theseor
other devices can help your child. Not all children who have hearing loss
should get cochlear implants. Doctors and hearing experts think they're
best for children who have a profound hearing loss and won't benefit from
hearing aids.
As children get older, many other devices are available to help
them hear. Some devices help children hear better in a classroom. Others
make talking on the phone or watching television easier. For example,
auditory training systems and loop systems can help eliminate
or lower other noises and make it easier for your child to hear someone
in a crowded room or group setting. Others, such as FM systems
and personal amplifiers, are better for one-on-one conversations.
Ways of helping children with hearing loss express themselves and interact
with others:
Oral/Auditory
options combine hearing, lip-reading, and hearing devices such as
hearing aids and cochlear implants. The goals of oral/auditory options
are to help children develop speech and English-language skills.
American Sign Language (ASL) is a language used by some deaf
children and their families. ASL consists of hand signs, body movements,
facial expressions, and gestures. It's a language with its own grammar
and syntax, which are different from English. ASL has no written form.
Cued speech is a system that uses handshapes in different locations
along with the natural mouth movements to represent speech sounds. Watching
the mouth movements and the handshapes can help some children learn
to speech-read English; this is especially important in discriminating
between sounds that sound different but look the same on the lips.
Signed English is a system that uses signs to represent words
or phrases in the English language. Signed English is designed to enhance
the use of both spoken and written English.
Combined options use portions of the various methods listed above.
For example, some deaf children who use oral/auditory options also learn
sign language. Children who use ASL also learn to read and write in
English. Combined options can expose children who are deaf or hard of
hearing to many different ways to communicate and express themselves.
The option you choose will depend on how you want your child to learn
and communicate. Find out about all of the choices and talk to lots of
experts.
You can do a lot to help your deaf or hard-of-hearing child to develop
strong academic, social, and emotional skills and succeed in school.
Find out how your school system helps children with hearing loss.
With your input, your child's school will develop an Individualized
Education Program for your child.
Explore programs outside of school that may help you and your
child, and talk with other parents who have already dealt with these
issues.
Remember, the Individuals withDisabilities Education Act
(IDEA) ensures that children with hearing loss receive free, appropriate,
early intervention programs from birth throughout the school years.
