Hearing Tests for Babies: What to Expect

Before you bring your newborn home from the hospital, she’ll get a tested for any hearing problems. The results should help ensure that she is able to learn and communicate without delays as she grows.

Why The Test is Needed

Babies begin to soak up information as soon as they’re born. One of the most important learning tools they have is their hearing. Your baby will learn a lot when she listens to what’s going on in the world around her, including what you say to her.

Research shows that infants with hearing problems that are not known or addressed before they’re 6 months old may have trouble with speech and language as they get older. But if any hearing problems are found and addressed before 6 months, a child’s speech and language should develop at a normal pace. That’s why early testing is so important.

You might think your baby’s hearing is fine when it isn’t. Hearing loss can be subtle.

Many babies with hearing loss can hear some things, but they might not hear enough things to help them learn language. For instance, your little one may cry when she hears a door slam or a smoke alarm go off, but that doesn’t mean that she can hear a whisper or someone talking at normal volume.

Types of Tests

There are two hearing tests that are widely used to check newborn hearing. Which test your baby gets depends upon where you live, because every state has its own screening method.

Both tests are ideal for spotting hearing problems in newborns. They are called the auditory brainstem response (ABR) test and the otoacoustic emissions (OAE) test.

ABR: This method finds out whether or not your baby’s hearing nerves, which carry sound from each of her ears to her brain, work well.

What happens: During the test, doctors place soft earphones in your baby’s ears and attach three small electrodes to her head. The doctor plays different sounds through the earphones, then measures how well each ear’s hearing nerve responds, with the help of the electrodes. It only takes a few minutes, and the screening won’t cause your baby any pain. She won’t know that her ears are being checked. In fact, she can sleep right through the test.


OAE: Doctors use this method to see whether your baby’s ears have the correct response when they’re exposed to sounds. In a normal ear, sounds create an echo, which doctors can measure.

What happens: During the test, doctors place small probes into your baby’s ear canals. The doctor plays different sounds, and the probes in your baby’s ears measure the echo response to the sounds in each ear. Just like the ABR test, your baby won’t notice that she’s being screened. It’s a quick, painless process.

What the Results Mean

Don’t be alarmed if your newborn doesn’t pass her hearing test. Some babies with normal hearing don’t pass this first screening. There are many reasons why this may happen:

  • The test was given in a noisy room.
  • The person giving the test didn’t have enough experience.
  • The earphones or probes didn’t fit into your baby’s ears well.
  • Your baby moved around too much during the test.
  • There was fluid in your baby’s ears when she was tested.

If your child didn’t have a normal hearing test, she’ll need to see a special hearing doctor, called an audiologist, before she’s 3 months old. When you take her to see this doctor, she’ll take follow-up tests to see if there’s really a hearing problem. If there is, the doctor will find out what’s causing the problem and how much hearing loss your baby has. Sometimes, the doctor may send you to an ear-nose-throat specialist for your baby’s treatment.


There are many treatment options for babies with hearing loss. Your doctor should provide your baby with one before she is 6 months old. The younger she is when she begins to have help with her hearing, the easier it will be for her to speak and understand language without delays.

Your doctor may suggest:

  • Hearing aids or another hearing device
  • Cochlear implants, which are special devices that help people with profound hearing loss
  • Learning sign language to communicate with your baby

When your baby gets older, other devices and services may help her hear or communicate more easily at home and at school.
