The auditory brainstem response (ABR), also known as auditory evoked potential (AEP) test, is a painless and non-invasive test that evaluates the functioning of the inner ear and brain pathways.

Our team of North American and European Board Certified otolaryngologists conduct ABR tests to test hearing thresholds and assess the functional status of the auditory neural pathway to determine the cause of hearing loss and recommend hearing loss treatments catered to the patient’s medical needs.

How is the test performed?

The ABR test is conducted while the patient is lying down in the sound booth or in the operating room for selected cases. Patients are required to remain still and quiet throughout the test to achieve optimal results. Infants and young children may require sedation prior to the test to ensure its effectiveness.

During the test, the physician attaches adhesive recording electrodes on the patient’s forehead and ears to capture and analyze recordings of electric potentials generated by the auditory neural pathway, the network of nerves that move from the ears to the brain.
