Auditory Brainstem Response (ABR) tests measure reactions of the auditory nerve in response to stimuli. It is a popular method to screen for hearing loss, especially for infants and young children who are not old enough for behavioral response hearing screenings.
An ABR test takes one to two hours. During the test, a young child must be asleep. Older children are sometimes sedated in order to relax.
When conducting the test, an audiologist places electrodes on the child’s forehead and ears. The electrodes are connected to a computer to monitor brain activity. The child will wear a pair of earphones and the audiologist will play a series of tones through them. These tones cover a broad range of frequency levels.
After the test, the computer prints a report indicating how the child’s auditory nerve responded to each pitch. While the test is not comprehensive enough to be used to prescribe or fit hearing aids, it does indicate whether or not hearing loss is present.
