Newborn Hearing Screening

  • Newborn Hearing Screening

    All hospitals in the United States screen for hearing loss. These simple very relatively quick screening tests are done in the nursery usually before the babies are discharged home.

    We have two methods to test newborn hearing. One is called otoacoustic emissions and the other is auditory brainstem response. The OAE or otoacoustic emission, we put a small ear probe in the baby’s ear canal and then play a sound and the ear sends back an echo. That test on a sleeping infant can take less than a minute. We test each ear. It’s important to know how the hearing is in both ears. So if the baby passes that test we wouldn’t necessarily recommend another test unless there were certain what we call risk factors for developing hearing loss later in life.

    For the ABR we actually put little electrodes on the head, usually one on the forehead and one behind each ear. And then again we play a sound to the ear and we can measure the response and we are measuring the response from these little electrodes.

    Both newborn screening tests​ are completely painless. They are very safe to do on newborns. They are relatively reliable, but they are a screening test. If the baby doesn’t pass the newborn screening regardless of what method is used, we will want to do a more complete test.
