Hearing Evaluation in children-BERA Test
BERA (Brainstem evoked response audiometry), ABR (Auditory brain stem response), BAER (Brainstem auditory evoked response audiometry). BERA is an electro-physiological test procedure which studies the electrical potential generated at the various levels of the auditory system starting from cochlea to cortex. This investigation was first described by Jewett and Williston in 1971. Procedure: The stimulus…
