Cortical Evoked Response Audiometry is used to determine the degree of hearing loss in adult populations who will not co-operate or who are unable to respond to standard audiometric procedures.

Neurological responses in response to a sound stimulus are recorded by placing electrodes on the head. The presence or absence of a repeatable response assists the audiologist in the estimation of an individual’s hearing acuity.

No response from the patient is required. The test is completely objective.
