Auditory Brainstem Response Evaluations (ABR)

What is an ABR?

Auditory Brainstem Response Testing, also known as ABR Test, is a method of measuring how well
the auditory system functions. The test requires no participation from the patient, allowing the
test to be completed on patients as young as 2 weeks old. To complete the ABR, the audiologist
places earbuds in the patient’s ears and small stickers called electrodes on the forehead and
behind the ears. The audiologist then measures the patient’s brain activity in response to
low-level clicking sounds played through the earbuds. Schedule your auditory brainstem response with us in Brooklyn, NY.

When do we perform an ABR?

1. To check for possible hearing loss when the patient cannot perform a typical hearing test, for example infants 0-12 months as well as adults and children with various disabilities.

The ABR is most typically performed after a baby does not pass their Newborn Hearing Screening in the hospital. All newborns are required to have a hearing test before leaving the hospital. Some newborns do not pass the hearing screening and are then instructed to follow-up for additional testing. Oftentimes, a newborn does not pass their hearing screening due to debris in the ear canal from the birthing process, fluid in the ears, or noise during the screening. However, follow up testing via ABR would be necessary to rule out significant hearing loss.

2. To measure how effectively sound is transmitted from the inner ear (hearing nerve) to the lower part of the brain (brainstem).

How do I prepare for an ABR test?

Depending on what type of ABR test is being performed, the test can take anywhere from 30 minutes to 2 hours. If the ABR is being performed on an infant, the infant must sleep during the test. It is best to bring the infant to the appointment sleepy but not yet asleep. The audiologist will prepare the infant for testing by placing the stickers and earbuds then allow the parent/caregiver time to put the infant to sleep. Once the infant is asleep, the test can begin. If the ABR is being performed on an older child or an adult, the patient only needs to sit quietly on a comfortable chair and close their eyes while the audiologist performs the test.
