How Do They Test Newborn Hearing

Can I Assume That Middle Ear Fluid Is The Reason For The Failed Test

ESSENTIAL – How They Do Newborn Baby Hearing Test

No. The newborn hearing screen cannot determine the cause of hearing loss. About 90 percent of the time, hearing loss goes away when the fluid does, but 10 percent of children may still have a hearing loss that need further medical attention. For this reason, it is very important to retest your childs hearing after fluid is gone.

Hearing Loss In Babies

1 to 2 babies in every 1,000 are born with permanent hearing loss in 1 or both ears.

This increases to about 1 in every 100 babies who have spent more than 48 hours in intensive care.

Most of these babies are born into families with no history of permanent hearing loss.

Permanent hearing loss can significantly affect babies’ development.

Finding out early can give these babies a better chance of developing language, speech and communication skills.

It will also help them make the most of relationships with their family or carers from an early age.

Why Is It Important To Screen For Hearing Loss In All Newborn Infants

Significant hearing loss is the most common disorder at birth. Approximately 1%-2% of newborns are affected.

Several national committees, including the National Institutes of Health, the American Academy of Otolaryngology/Head and Neck Surgery, and the American Academy of Pediatrics, have recommended that hearing loss in infants be identified, and when possible treated, prior to 6 months of age.

This recommendation is based on studies that have shown that children identified with hearing loss prior to 6 months of age have a better chance of developing skills equivalent to their peers by the time they enter kindergarten.

Children not identified until later may ultimately suffer from irreversible and permanent impairments in speech, language, and cognitive abilities when compared to their peers.

Prior to the implementation of hearing screen programs, it was customary to only test those newborns who had known significant risk factors for hearing loss. This group included infants whose mothers suffered from illness during pregnancy, those who had a family history of hearing loss, or those who were exposed to drugs known to affect hearing. In addition, infants with the following conditions were included for hearing screening:

However, despite the testing of all infants who fell into this “high-risk registry,” over half of all newborns with hearing loss were missed!

Your Babys Visit To The Audiology Clinic

Audiology clinics have special equipment to test your babys hearing. These tests will give better information about your babys hearing.

Early testing means you will know if your baby has a hearing loss when they are still very young. This is important for their future development.

Your baby needs more tests because their hearing screening tests did not show a clear response in one or both ears. About 2 to 3 babies in every 100 do not show a clear response and are referred to audiology.

Most babies tested at an audiology clinic are found to have satisfactory hearing.

About 1 in 15 babies tested at the audiology clinic have a permanent hearing loss in one or both ears. Some have a temporary hearing loss. Finding out about hearing loss early gives babies a better chance of developing language, speech and communication skills as well as making sure their families receive the support they need.

It is important you bring your baby to the appointment. This is because they may need other tests to find a possible cause if they do have a hearing loss. These tests should be performed within the first few weeks of birth.

Some babies who have a hearing loss do react to sounds. The hearing loss may not be picked up without the tests in audiology.

If your baby does have a hearing loss, it is important to find out as soon as possible.

Hearing Tests For A Toddler

A day in the life of a newborn hearing screener

A toddler’s hearing assessment may include the tests mentioned above, along with these:

  • Play audiometry. A test that uses an electrical machine to send sounds at different volumes and pitches into your child’s ears. The child often wears some type of earphones. This test is changed slightly in the toddler age group and made into a game. The toddler is asked to do something with a toy every time the sound is heard. This test relies on the child’s cooperation, which may not always be possible.

  • Visual reinforcement audiometry . A test where the child is trained to look toward a sound source. When the child gives a correct response, the child is rewarded through a visual reinforcement. This may be a toy that moves or a flashing light. The test is most often used for children between 6 months to 2 years old.

All Babies Should Have A Hearing Screening Before They Are One Month Old

Hearing screening is easy and is not painful. In fact, babies are often asleep while being screened. It takes a very short time usually only a few minutes. Sometimes the screening is repeated while the babies are still in the hospital or shortly after they leave the hospital.

Babies who do not pass hearing screening should be tested by an audiologist. An audiologist is a person trained to test hearing. This person will do additional testing to find out if there is a hearing loss. There are many kinds of tests an audiologist can do to find out if a baby has a hearing loss, how much of a hearing loss there is, and what type it is.

Your Baby Probably Had A Hearing Screening

Almost all states, communities, and hospitals now screen newborns for hearing loss before the babies leave the hospital. The hearing screening is easy and painless, and it can determine if more testing is needed. In fact, many babies sleep through the hearing screening, and the test usually takes just a few minutes.

If You Dont Test Babys Hearing At The Hospital

While the standard is to test a babys hearing before theyre discharged from a hospital or birthing center, that doesnt mean it always happens.

You should get your babys hearing checked before they reach 1 month of age. Typically, your babys healthcare professional can schedule the test. If your baby doesnt pass this test, your pediatrician may recommend working with a pediatric audiologist.

Newborns in the neonatal intensive care unit arent always screened within the first few days of life. Often this test may be delayed until theyre medically stable or ready to be discharged.

Additionally, parents who opt for at-home births will need to work with their doctor to schedule a hearing screening before their baby is 1 month old.

Usually, the newborn hearing screening is a standard diagnostic thats performed shortly after birth in medical facilities across the United States. In fact, in 2019, 97.7 percent of babies born in the United States had their hearing screened before reaching 1 month old.

These tests dont pose a risk to your baby and wont hurt them. Often the test is administered while your little one is snoozing. And in some cases, your baby may receive both tests. Each test takes no more than 5 to 10 minutes to complete.

About The Infant Hearing Program

Hearing loss can develop during early childhood. It is important to pay close attention to your babys speech and language development as any issues may be a sign of hearing loss.

It is important to detect hearing loss as early as possible.

The Infant Hearing Program provides:

  • hearing screening for all newborns in hospital or community settings
  • assessments to identify permanent hearing loss
  • monitoring of children at risk of developing hearing loss
  • language development services

Two out of 1,000 babies have hearing loss at birth. Two more out of 1,000 develop hearing loss by the age of five. These children may hear some sounds but miss others, making it harder to learn speech and language. This can lead to behavioral and learning challenges.

What Happens If The Baby Fails The Hearing Test

How do you test a newborns hearing?

When the newborn child does not respond to the OAE test as expected, the doctors conduct the test again. This is because a newborn with perfect hearing may also fail the OAE hearing test. The reasons for the failure of the test could be a gathering of debris in the ear canal, a noisy room while performing the test, or if the baby keeps crying. All this makes it difficult for the baby to pass the test. It is observed that babies who fail the test for the first time often successfully pass the test on the second attempt.

If your baby fails the OAE test for the second time, then the audiologist will conduct an AABR test to be certain that there is indeed a hearing problem. After this, follow up tests are done, which are more thorough and will involve other professionals like the Early Intervention Specialist, Paediatric Audiologist, and an ENT Physician.
