What should you know about an AABR hearing test?

Soft sounds are delivered through earphones while equipment records electrical responses. The test does not require the person being tested to press a button or describe what they hear.

A clinician cleans small areas of skin and attaches sensors to the head. Remaining still and relaxed helps produce a clear recording, so testing may be arranged during natural sleep for babies or quiet rest for others. The equipment compares the recorded nerve activity with the sound presented.

A screening outcome is not the same as a complete diagnosis. A result that needs follow-up can occur when responses are unclear, and ear canal blockage, fluid, movement or electrical interference may affect the recording.

Follow the clinic's instructions about sleep, feeding or skin products before the appointment. Bring previous hearing results and mention ear infections, ear surgery, medicines that may affect hearing, tinnitus, dizziness or a family history of hearing difficulty.

If the report recommends repeat screening or diagnostic audiology, arrange it promptly. Further assessment may use additional methods to identify the type and degree of any hearing difficulty and guide communication support or treatment.

Seek urgent medical assessment for hearing that drops suddenly in one or both ears, especially with new ringing, severe dizziness, weakness, facial droop or other neurological symptoms. Ear pain with discharge, fever, injury or a suspected object in the ear also needs timely review. Do not wait for a routine AABR appointment to assess these problems.

Ask whether each ear produced a clear response, whether the result was a screen or a diagnostic assessment, and what follow-up is recommended. You can also ask whether earwax, middle-ear fluid or movement may have influenced the recording.
