BERA (Brain stem Evoked Response Audiometry)
This evaluation is done to assess the functioning of auditory path way. This is also used as an objective measure of hearing in infants and children. For this test child should be completely relaxed/sleep mode, as the body movements may affect the neural response. Audiologist place a transducer in the ear canal, which provide specific sounds ( ex: click/tone burst) to the ear. Different electrodes are placed on the child would record the neural response from the auditory pathway and other brainstem structures. These recordings will be analyzed by the audiologist and make diagnosis accordingly.
