Reasong For Hearing Test Failures
Older children can also fail their hearing test for a number of reasons. Fluid in the ear or excess wax can negatively affect the results. Its best to have a trained audiologist in Louisville perform a hearing test in a clinical setting in order to be sure.
There are several different hearing tests that an audiologist can administer, based on your childs age, development and health. These include:
- Auditory brainstem response test. Clicking sounds are transmitted through earphones, and electrodes measure the auditory systems response.
- Otoacoustic emissions test. Pulse-type sounds are delivered through a probe in the ear canal, and the echo response from cells in the inner ear is recorded.
- Tympanometry. Soft sounds and air pressure are introduced in the ear canal to measure movement of the eardrum.
- Middle ear muscle reflex . A rubber tip is inserted in the ear canal, and a series of sounds that should trigger reflexes are delivered through the tips.
If your infant or child fails any of these hearing tests, solutions are available to assist their growth and development. Contact Heuser Hearing Institute to schedule an appointment today.
What Happens If Baby Doesn’t Pass Hearing Test
If your baby does not pass the hearing screening at birth, it does not necessarily mean that she is deaf or hard of hearing. Fluid or vernix inside the babys ear, for example, or too much noise in the room can affect results. In fact, most babies who do not pass the newborn screening have typical hearing.

Signs of hearing loss in your baby can include:
Failed Newborn Hearing Screening
My son is 7 weeks old and he failed the newborn hearing test in the hospital twice. The nurses said its common and 99% of babies pass the hearing test later on. LO was born via c-section and could have had a lot of junk from delivery still in his ears. Well for the first few weeks I googled hearing loss until I made myself crazy. Then I started o realize he can hear. A large picture fell off the wall and he jumped. He does startle to loud sounds. We have to see an Audiologist just as a precaution at the end of the month. Well, last week LO had RSV and was hospitalized. He is doing great now and we saw his dr for a follow up this morning. Another side note LO was born with a small patch of white hair, which I was told he just didn’t have any pigmentation there. I think it’s adorable! The dr decided to tell me today that sometimes white patches of hair are linked to hearing loss!! Now I’m googling again and worried sick! She is moving his Audiology appointment up because she Wanted to give me a peace of mind and if there was hearing loss we could start some interventions ASAP! My husband and my mom seem to think he can hear fine and are not worried. Has anyone else had any experience with this? I know hearing loss is not the worse thing in the world, but I still don’t want anything wrong with my baby… I’m just so worried!

How Do You Know If Your Baby Has Hearing Loss
The Centers for Disease Control and Prevention and the American Academy of Pediatrics recommend that all babies get screened for hearing loss before theyre 1 month old. Most babies get their hearing checked as part of newborn screening before they leave the hospital after birth. Newborn screening checks for serious but rare and mostly treatable health conditions at birth. It includes blood, hearing and heart screening.
If your baby doesnt pass her newborn hearing screening, it doesnt always mean she has hearing loss. But she needs a full hearing test as soon as possible before shes 3 months old. A full hearing test can help your babys health care provider diagnose hearing loss.
If your baby has hearing loss, getting treatment right away is important. Every state has an Early Hearing Detection and Intervention program that works to help children with hearing loss and their families. It can help with full hearing tests and other services for your baby. You can find your local EHDI program through the National Center for Hearing Assessment and Management website.
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 device’s increased sensitivity to residual amniotic fluid and vernix that is commonly found in the neonate’s 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.

Who Should Be Screened With Algo
All infants who meet the following criteria may be screened with the ALGO machine:
- Term, healthy newborn
- NICU graduate, 34 weeks gestational age or older
- Newborns with normal external ear and no obvious head or neck deformity
- Ready for discharge
- Receiving NO central nervous system stimulants
- In an open crib
- Sleeping or in a relaxed state
If My Baby Seems To Hear Normally Can The Tests Be Wrong
Parent assessment of child hearing is not always accurate, so it is important to have the childs hearing professionally tested. Just because a baby reacts to sounds does not mean the child has full range of hearing a baby may hear certain sounds but not others. Only a professional hearing test that checks each ear separately can accurately tell how your child hears.

How Will I Know If My Child Has Trouble Hearing
My husband has had a hearing loss since he was a child. How will I know if our baby also has a hearing problem? Joyce
A family history of hearing loss does put a newborn at higher risk for having a hearing loss. But rest assured, your baby’s hearing can be monitored closely so that if there is a problem, treatment can begin as soon as possible.
In most states, hospitals do a newborn hearing screening before the baby goes home. If it’s not done then, or the baby was born at home or a birthing center, it’s important to get a newborn hearing screening within the first 3 weeks of life.
A baby who doesn’t pass a hearing screening doesn’t necessarily have a hearing loss. A retest to confirm the hearing loss should be done within the first 3 months of life. If it confirms a problem, doctors should start treatment by the time the child is 6 months old.
Even if your newborn passes the initial hearing screening, watch for signs that he or she is hearing well. Hearing milestones that should be reached in the first year of life include:
- Most newborns startle or “jump” to sudden loud noises.
A child may be at higher risk for hearing loss if he or she:
- was born prematurely
- was given medicines that can lead to hearing loss
- had complications at birth
Treatment For Hearing Loss In Infants
If your baby fails the threshold ABR hearing rescreening and indicates hearing loss, he/she will be referred to an ENT physician for a complete medical evaluation. If the hearing loss is medically treatable, the ENT will treat the underlying medical condition as needed. If the hearing loss is deemed not medically treatable then the baby will be referred to the audiologist for further follow up including a hearing aid evaluation.
Hearing loss due to damage to the inner ear or to the nerves that relay sound to the brain requires early intervention with therapies and services designed to help your baby learn to recognize sounds and develop speech and language appropriately. The audiologist may recommend hearing aids, a cochlear implant evaluation, and/or a referral to the county early intervention program that includes speech and language therapy.
Early detection of hearing loss in newborns is important in preventing learning and developmental delays.

Failed Hearing Test Follow Up Is Key
A significant number of infants fail their first hearing screening due to fluid that may still be present in the ear canal right after birth. If your infant doesn’t pass the initial hearing screening, schedule a follow-up screening with a pediatric audiologist within a couple of weeks. The majority of infants will pass the second screening quite easily. For those who do not pass the second newborn screening, a diagnostic hearing test from your pediatric audiologist will investigate further.
If your infant fails their newborn hearing screening, its important to follow up as soon as possible to determine whether or not they have hearing loss and, if so, when to begin treatment or services. Experts encourage parents to meet with an audiologist who specializes in infants, a pediatric ear, nose and throat doctor , and a pediatric eye doctor since some babies with hearing loss also have problems with their vision. You may also want to meet with a geneticist to determine if your babys hearing loss is hereditary.
Most likely, your pediatrician can recommend a hearing healthcare professional who specializes in children.
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.

How Accurate Are Hearing Tests On Newborns
Although the test is relatively accurate, it sometimes fails to detect hearing impairments. This is known as a false negative test result. Sometimes newborns with normal hearing get a wrong diagnosis after having an OAE test: Although they can hear well, they are mistakenly diagnosed as being hard of hearing.15 2008 .
What Can I Do If There Is No Nhs Program Provided In My Country/hospital
Universal newborn hearing screening is being implemented in more countries around the world every year, but still many countries do not have programs in place. In some areas, the resources for infant hearing screening and the follow-up services for diagnostic testing are very limited or do not exist locally.If universal newborn hearing screening is not available in your area/hospital or you have concerns that your child does not hear properly, your best resource for information is likely to be one of these professionals.
- Your babys doctor
- An ear, nose and throat specialist
- An Audiologist in a hospital or clinic
- An administrator in your school district

How do they test a babys hearing
The concept of checking a babys hearing seems a bit crazy. How can you test the hearing of a baby that cant tell you if they hear something or not?
Your baby actually doesnt have to do anything during the test, in fact, the less they do the better! They check a babys hearing by testing for a brainstem response. They use equipment to see if the auditory nerve is responding to various sounds of different levels of loudness and different frequencies.
What happens at the test
For the retest you will be asked to bring your baby to the test tired and hungry. Its one of the few times someone will actually request that you bring a cranky baby!
The audiologist will take you back to a quiet room and have you nurse or give a bottle to the baby and get them to sleep.
For us, they attached the little electrodes to my babys head just as we started nursing to minimize what they needed to do once she was asleep. Once she was out they put a tiny item into each of her ears.
Once you baby is fast asleep they will begin the test. It takes 5-15 minutes depending on how many frequencies they are testing. For our first test they only did a very low quiet sound. My daughter once again failed.

What Else Should I Know
If your child is diagnosed with a hearing problem, the audiologist will work closely with doctors, speech-language therapists, and education specialists to create a treatment plan for your child.
It also can help to meet other families of kids with hearing loss. Reach out to a local support group or ask a member of your care team about local programs where you can connect.

How Newborn Hearing Screening Works
Babies can cry a lot during routine medical procedures, but rest assured, newborn hearing screenings are safe and comfortable. Many infants sleep through the entire procedure, which usually only takes a few minutes.
Heres a quick description of the two most common tests your newborn may experience:
- Otoacoustic emissions measures your babys response to sound by placing a miniature earphone and microphone in the ear. Normal hearing triggers an echo into the ear canal, which is measured by the microphone. If your baby has hearing loss, no echo is recorded. The screening is done on each ear and a passing result confirms that the infants inner ears are receiving sounds.
- Auditory brainstem response measures how the auditory nerve responds to sound through small electrodes placed on your babys head. This screening is a more complete test of the auditory system, and it requires small electrodes to be taped to the baby’s scalp. The screening is again done for each ear and a passing result confirms that the infants brain is receiving sound.
Your baby may have both tests together, one at a time, or the ABR only if they fail the OAE. Hospitals determine which tests they use based on costs, personnel and the number of babies born.
