Also known as BSER or ABR, Auditory Evoked Potentials may be used to estimate hearing in infants, young children and others who cannot participate in behavioral testing.
To perform the test, special electrodes or sensors are placed on the forehead and behind each ear. A soft rubber earphone is placed in the ear and sends a series of sounds into the ear. The sensors measure the response of the hearing nerve. Although not a direct test of hearing, the Auditory Evoked Potentials threshold responses are generally in agreement with hearing thresholds. Auditory Evoked Potential testing is also considered an effective screening tool in the evaluation of suspected hearing nerve problems.
