What Happens If There Is A Problem
If your baby does not pass the hearing test the first time, the test will be done again. The repeat test is usually done 12 to 24 hours after the first test.
If your baby does not pass the second test, they will be referred for a diagnostic audiology assessment. This assessment is done by an audiologist , ideally when your baby is 4 to 6 weeks of age so your baby can get support if hearing loss is diagnosed.
Is Nbs The Same For All Babies In The Us
Even though every state in the U.S. requires NBS, each state manages its own NBS program. This means that NBS can be a little different in each state.
For example, some states may give parents different options during screening, have different NBS costs, or look for different conditions during screening. It is important to be familiar with how NBS works in your state.
To learn about NBS in your state, visit the State pages.
When Will The Hearing Test Take Place
Youll be offered a hearing screening test for your baby within the first few weeks of their life from 12 hours old. The hearing test is usually done before you leave the maternity unit. In some areas, it will be carried out at home.
Your midwife or screener will be able to tell you where and when the screening test will take place. If your babys hearing is not screened, ask your child health nurse, midwife, local audiology department or family doctor to arrange an appointment.

Oaes And Abrs Is One Test Better Than The Other
Both tests have advantages and disadvantages when used for screening, and depending on the program and experience of the audiologist, either one can be utilized successfully.
- The OAE is easy and cost-effective. However, the false-positive rate may be higher for an OAE than for an ABR.
- The false-positive rate for ABR testing is approximately 4% when testing is done during the first three days of life.
- The false positive rate for OAE testing is 5%-21% for testing done during the first three days of life.
- This large variation between ABR and OAE testing is commonly felt to reflect the OAE testing devices increased sensitivity to residual amniotic fluid and vernix that is commonly found in the neonates ear canal.
The two tests, however, rely on different mechanisms of hearing for the screening. For in-depth testing and a complete hearing evaluation of infants, these tests work best together as a complement to each other.
Why Hearing Screening Is Important
- Hearing loss is the most common disorder in infants and affects one to three out of every 1,000 babies born each year.
- Genetic factors can cause hearing loss in some babies, especially if there is a family history of hearing loss.
- Delayed detection of hearing loss can lead to communication, social, psychological, behavioral, and educational challenges.
- The American Academy of Pediatrics recommends that all infants be screened by one month, diagnosed by three months, and start getting early intervention services no later than six months.

Why Is Newborn Hearing Screening Important
The earlier audiologists discover hearing loss in an infant, the better. They can begin working with appropriate specialists sooner, and your baby will be less likely to have problems communicating in the future.
Babies learn the foundations of language in the first three years of life. Their brains are developing the skills to communicate. Children with hearing loss will develop better language skills if they get diagnosed and receive aid earlier.
What Should I Know About The Newborn Hearing Screening
- Hearing screenings are fast, safe, and painless.
- Sometimes newborns are screened once or twice.
- Hearing screenings take about 10 minutes.
- Most babies sleep through the hearing screening. If your baby is noisy or restless during screening this can influence the results.
- You will receive the hearing screening results before you leave the hospital.

What Is The Newborn Hearing Test For
The newborn hearing test is a routine health check that will be offered to your baby soon after birth. The newborn hearing test is used to help detect hearing loss in babies. Your baby needs to hear to learn speech and language skills. If your baby has hearing loss from birth its important to diagnose this soon after birth. Early detection can help you and your health team take steps to improve your childs language, as well as encourage their social and emotional development.
Before Newborn Screening: Questions To Ask
Many parents have questions about NBS. Following is a list of questions that you may want to ask your health care provider or your babys health care provider before your babys birth, before your babys screening, or while your baby is being screened.
- Will I need to ask for my baby to be screened?
- When does NBS happen?

Bc Specific Information Message
Hearing loss is the reduced ability to hear sounds. It can occur at any age and can be a gradual or sudden loss. Hearing loss can have many causes. The part of the ear involved determines the type of hearing loss. Depending on the cause, hearing loss can be mild or severe, temporary or permanent. For more information on hearing loss, see HealthLinkBC File #71a Hearing Loss in Children, and HealthLinkBC File #71c Hearing Loss in Adults. For more information on hearing tests for infants and children, see HealthLinkBC File #71b Hearing Tests for Infants and Children.
If you or your child is experiencing hearing loss symptoms or have questions about hearing loss, you can call 8-1-1 to speak with a registered nurse for advice anytime of the day or night, any day of the year.
About Newborn Hearing Screening Data
All babies are tested for signs of some possible health concerns. These tests are called screenings. Your baby will have a test at the hospital to check for concerns with his or her hearing. A special machine shows if your baby responds to sounds. The test is simple and does not hurt. You will get the results before you leave the hospital.

Babies And Hearing Loss
Babies can hear sounds in the womb before they are born. Thats why their parents voices are already familiar and comforting to them shortly after birth.
But some babies are born with hearing loss, says the National Institute on Deafness and Other Communication Disorders. Two to three of every 1,000 American children have some hearing loss in one or both ears at birth.
Newborn hearing screeningprograms currently operate in all U.S. states and territories. About 98% of infants have their hearing screened before one month of age.
Do Children With Hearing Problems Develop The Same As Other Children
It depends on how early the problem is diagnosed. Children who are diagnosed laterespecially after 2 years of agemay have lifelong problems with language, speech and literacy. If the hearing loss begins at a later age, especially after the child has started to talk, your childs language development may be less affected.
Success in school is linked to literacybeing able to read and write effectively. And literacy is linked to the hearing and speech areas in the brain. To be able to speak, children need to hear. Children who hear and speak learn to read and write more easily.
The first few months of life are critical for developing the speech and language area of the brain. Studies show that the earlier a baby can hear, the better their language skills will be. Deaf children who are diagnosed early and get the right kind of help can develop just like other children their age.

Will My Child Be Successful In School
Like all children, children who are deaf or hard-of-hearing can 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 childs school will develop an Individualized Education Program or Individualized Family Service Plan for your child, and you should ask if an educational audiologist is available to be part of the academic team. Explore programs outside of school that may help you and your child and talk with other parents who have already dealt with these issues. The Individuals with Disabilities Education Act ensures that children with hearing loss receive free, appropriate, early-intervention services from birth through the school years. Contact the U.S. Department of Education, along with resources listed in our directory of organizations.

What If My Baby Has Hearing Loss
If a newborn hearing screening indicates that your baby doesnt hear well, your pediatrician may recommend a pediatric audiologist that specializes in evaluations and management of hearing loss for children. They may also refer you to a pediatric ear, nose, and throat specialist.
If your baby has hearing loss, treatment could include:
- Assistive devices that work with hearing aids or implants to reduce background noise
- Speech therapy.
Fortunately, with current technology, hearing loss in babies can usually be caught early. You can get your child the help they need to communicate well as they grow.
What If My Newborn Passes The Hearing Screening
Most newborns who pass the hearing screening have normal hearing. However, some newborns might hear well enough to pass a screening, even though their hearing is not perfectly normal. It is a screening and not a diagnostic test, and so the newborn hearing screening cannot properly identify 100 percent of babies with hearing loss.
Additionally, some newborns may pass the screening at birth, yet they can lose hearing from illness, medications, or genetic reasons. This hearing loss can come on suddenly or gradually over time.
Because of these factors, it is important that, even if your newborn passes the screening, you contact your childs pediatrician and get a referral to an audiologist for hearing testing if you have any concerns for your childs hearing.

How Is The Hearing Test Done
The hearing test is usually done at the bed side while you and your baby are still in hospital. The hearing screener will explain the test and ask you to sign a consent form.
Some Australian states use the automated auditory brainstem response screening test. For this test, the screener places ear cups on your babys ears that play a soft clicking noise. Sensors are placed on your babys forehead, neck and shoulder to measure how the auditory nerve responds to the sounds played. The auditory nerve transfers sound from the cochlea in the inner ear to the brain. The test is quick and painless. Your baby can sleep or feed during the test.
Other states use a different screening test, known as the TEOAE hearing test. This test is done by placing a probe in the ear canal that makes soft sounds. This test is also quick and painless.
What Is Newborn Infant Hearing Screening
- Newborn infant hearing screening programs are designed to identify hearing loss in infants shortly after birth.
- All states have implemented these screening protocols within hospitals and birthing clinics.
- Most hearing screening tests are done prior to discharge from the hospital or birthing clinics.
- Typically, nurses or medical assistants are trained extensively on how to operate automated equipment for testing infants. Prior to discharge, each newborn has his/her hearing tested. If, for some reason, the newborn does not pass the screen, a rescreen is usually done. If the infant does not pass the second hearing test, he/she is referred to a specialist for further testing.
- Specialists who are experts at testing hearing are called audiologists. Audiologists have had training that emphasizes diagnostic hearing testing techniques as well as hearing rehabilitation of children and adults. Their postgraduate academic training requires a minimum of a masters degree.

Factors That May Affect Your Infants Hearing
There are various factors that might affect a newborns hearing. Here are some of the common reasons .
- Cytomegalovirus infection
- Antibiotics such as gentamicin, tobramycin, kanamycin, and streptomycin
- Earwax or fluid behind the eardrum
- Objects such as toy, crayons, or food stuck in ear canals
- Being surrounded by machines that make loud sounds
Hearing loss in babies can display the following characteristics.
- It can be unilateral, bilateral, or both.
- Be mild, moderate, severe, or profound in intensity.
- Profound hearing loss is commonly called deafness.
- In some babies, the inability to hear worsens with time.
Automated Auditory Brainstem Response
With the AABR test, technicians are measuring how your babys auditory nerve, the hearing nerve, and brain stem respond to sound.
Your baby will have small headphones placed on their ears and sticker-like electrodes placed on their head. Since babies cant tell test administrators what they can or cant hear, the electrodes measure the auditory nerve and brain stem response to gentle sounds like clicks or tones.

Why Are Newborn Hearing Screening Tests Important
Hearing loss can have serious repercussions on the babys development. It inhibits the child from learning how to speak. Newborns learn from the environment around them. While babies with hearing problems can learn visually, they will be unable to pick up speech as they cannot decipher the sounds around them. A conversation initiated by the mother may sound like nothing more than muffled noises. This eventually results in impaired speech.
A hearing test can catch this impaired hearing, and the child can be sent for speech therapy. According to audiologists, children treated for hearing loss in time will never have difficulties in speech, language skills, reading and writing.
As informed earlier, hearing test for infants includes the Otoacoustic Emission Test and the Automated Auditory Brainstem Response Test . The type of test that is performed largely depends on the hospital. Some hospitals perform both tests, which is more thorough but could be more expensive. Others first screen for OAE, and only if the newborn fails this test do they perform an AABR test.
What Are Some Signs That A Child Has A Hearing Problem
Without newborn hearing screening and special tests, the signs of hearing loss can be very hard to find. Sometimes babies and children seem very alert, so you think they can hear you well, but they are actually using their other senses to know what is going on around them. Or, as they get older, they learn to read your lips on their own.
If you are concerned about or suspect a hearing problem, or if you notice any of the signs listed below, see your doctor as soon possible and ask about a hearing test.

How Is The Newborn Hearing Test Done
The newborn hearing test is called the automated otoacoustic emission test. It takes just a few minutes.
A small soft-tipped earpiece is placed in your baby’s ear and gentle clicking sounds are played.
It’s not always possible to get clear responses from the 1st test. This happens with lots of babies, and does not always mean your baby has permanent hearing loss.
It could mean:
- your baby was unsettled when the test was done
- there was background noise
- your baby has fluid or a temporary blockage in their ear
In these cases, your baby will be offered a 2nd test. This may be the same as the 1st test, or another type called the automated auditory brainstem response test.
The AABR test involves placing 3 small sensors on your baby’s head and neck. Soft headphones are placed over your baby’s ears and gentle clicking sounds are played. This test takes between 5 and 15 minutes.
These tests will not harm your baby in any way.
How Will My Babys Hearing Be Screened
A newborn undergoes a hearing screening.
Two different tests are used to screen for hearing loss in babies. Your baby can rest or sleep during both tests.
- Otoacoustic emissions tests whether some parts of the ear respond to sound. During this test, a soft earphone is inserted into your babys ear canal. It plays sounds and measures an “echo” response that occurs in ears with normal hearing. If there is no echo, your baby might have hearing loss.
- The auditory brain stem response tests how the auditory nerve and brain stem respond to sound. During this test, your baby wears small earphones and has electrodes painlessly placed on his or her head. The electrodes adhere and come off like stickers and should not cause discomfort.

What Are The Types Of Hearing Tests
-
Automated Auditory Brainstem Response : It is a test that checks the brains response to sound.
-
During this test, your newborn wears tiny earphones that play sounds and, along with three electrodes placed on her scalp, they will measure brain activity as she listens. The child being tested can be sound asleep during the test. It takes around 10-15 minutes to perform, and results are automatically generated
-
Transient or Distortion Product Otoacoustic Emissions : This test uses a tiny probe that is inserted just at the entrance to your babys ear canal and emits a number of sounds. The test checks for echoes in your babys ears in response to the clicks or tones that are played. Baby can be sound asleep and the testing takes 5-10 minutes, and results are automatically generated.
-
Audiological Evaluation: An audiological evaluation, sometimes called a hearing assessment, is a group of tests that check different parts of the hearing system in order to identify how well the baby can hear the results of the evaluation are put on graph called an audiogram which shows the areas of hearing loss and degree of hearing loss .
