Can My Baby Hear Me?
What you need to know about newborn hearing screenings.

Rachel Epstein’s second child, Alana, was born in February 2001
with no apparent health problems. An uncomplicated delivery, Rachel
had no reason to suspect that anything was wrong with her daughter.
However, a newborn hearing screening soon discovered the unimaginable—
Alana was born profoundly deaf.
“My husband and I had no reason to believe that Alana was deaf.
We both have normal hearing and so does our older daughter, says Epstein.
“My pregnancy was normal and we knew of no hearing issues in our
families.” According to the American Academy of Audiology, most
babies born with hearing loss are born otherwise healthy with no family
history of hearing problems.
Each year, as many as three of every 1,000 babies born in the United
States are born with hearing loss. Because your newborn can’t
tell you if he can’t hear, it is important to have your baby’s
hearing tested before you leave the hospital after giving birth, or
shortly thereafter at an outpatient facility if your hospital does not
offer newborn hearing screening. This will give your baby the best chance
to develop speech and language skills.
“Had the newborn screening program not been in place in Connecticut
at the time Alana was born, we probably wouldn’t have discovered
the problem until she was 2 and at that age she would have missed the
most important years for speech and language development. Today, Alana
is a normal 2 ½ year old, testing at age level thanks to newborn
hearing screening,” says Epstein.
What Should I Do?
Right away, be alert to any signs of newborn hearing loss, such as failure
to be calmed by the sound of your voice. “A new baby will also
startle in response to a loud sound,” says Dr. Alison Grimes,
director of audiology at Providence Speech and Hearing Center in Orange,
CA.
It’s important for parents to be assertive. An audiological evaluation
is not very costly and does not hurt the baby. Parents need to be more
observant of their infant’s hearing,” says Grimes.
While newborn hearing tests have become common practice, not every state
requires a hearing screening at birth. To date, at least 32 states have
passed legislation requiring newborn hearing screening for all babies
born in the state, according to the National Center for Hearing Assessment
and Management.
“Parents are often unaware that, while nearly all babies born
in the United States undergo newborn screening tests for genetic birth
defects, the number and quality of these tests vary from state to state,”
says Dr. Jennifer L. Howse, president of the March of Dimes. Because
significant hearing impairment is one of the most common developmental
abnormalities present at birth, the March of Dimes advises a hearing
test for all newborns.
“If you live in a state without a program, discuss newborn hearing
screening with your hospital as part of the birthing process. As more
parents request the screening, hospitals will be forced to stand up
and take notice,” says Grimes.
How Will My Baby Be Screened For Hearing Loss?
The screening of newborns involves the use of non-invasive measures
that include otoacoustic emissions (OAEs), in which soft clicking sounds
are played in your baby’s ears and the inner ear’s response
to sound is measured, and/or auditory brain response (ABR), which tests
an infant’s ability to hear soft sounds through miniature earphones.
Both tests are painless and can be done while your baby is resting quietly.
New technology developed by Natus Medical Inc. in San Carlos, CA, now
enables both ears to be screened simultaneously. An ABR test is a hearing
screening that takes just four to seven minutes to complete and has
been found to demonstrate the highest clinically proven accuracy.
If your baby does not pass either the OAE or ABR, the test should be
repeated or your baby should be referred to a hearing specialist for
more extensive tests to detect hearing loss. An infant with hearing
loss should begin receiving treatment before 6 months of age.
When hearing loss is detected late, language development can be delayed.
Studies suggest that children treated this early are usually able to
develop communication skills that are as good as those of hearing peers.
“Alana has absolutely no ‘deaf speech,’” says
Epstein. “She is a little chatterbox. Strangers ask me how old
she is and are always surprised to hear that she is 2 ½ because
she talks so well. If they only knew she was profoundly deaf.”
If your child is found to have hearing loss, there are a number of treatment
options available. You will need to consult with your doctor to determine
which are most appropriate for your child. Your child’s age, developmental
level and personality, the severity of the hearing loss, as well as
your own preferences should be considered in this decision.
