The measured recording is a series of six to seven vertex positive waves of which I through V are evaluated.

Brainstem evoked response audiometry is useful in the identification of threshold levels as well as in the diagnosis of eighth nerve tumors.

The quantitative assessment of individual hearing, either normal or defective. Three types of audiometric tests are used: pure tone, speech, and bone Explanation of brainstem evoked response audiometry Brainstem-evoked response audiometry (BERA) is a simple, noninvasive, objective test for early identification of hearing impairment in children and neonates. It can be used as a screening test and is useful in newborns, infants, and other difficult-to-test patients. Audiometry Definition Audiometry is the testing of a person's ability to hear various sound frequencies.

AUDITORY NERVE AND BRAINSTEM POTENTIALS Auditory nerve and brainstem evoked potentials (ABEP) are optimally recorded from the scalp by disc or cup electrodes in response to high intensity clicks presented at a rate of approximately ten per second. The normal waveform includes a series of five to seven voltage oscillations, approximately 1 ms apart during the first 6-10 ms after stimulus onset.

Brain stem evoked response audiometry (BERA) is an effective method of evaluating the auditory pathway from the peripheral endorgan through the brain stem. The authors have found this test to be a valuable adjunct to the neurotologic evaluation and have applied the study to over 500 patients (639 ears) in a 22 month time span. Brainstem Evoked Response Audiometry (BERA) is an objective and non-invasive method of hearing assessment which detects electrical activity from the inner ear to the inferior colliculus. AIM: To assess the hearing pathway in normal hearing individuals and compare differences associated with gender, age and ear side (left and right). AUDITORY BRAINSTEM RESPONSE (ABR) IN CLINICAL PRACTICE Leigh Biagio de Jager Auditory Evoked Potentials (AEPs) are not measures of hearing per se, but are highly correlated with, and provide accurate behavioural pure tone thresholds 1–4.
