BERA Evaluation

BERA (Brainstem Evoked Response Audiometry) is also mentioned as Auditory Brainstem Responses is an electro-physiological test procedure to measure the responses of brain waves stimulated by a clicking sound to identify the central auditory or hearing pathways of the brainstem.

Brainstem evoked response audiometry (BERA) aids is an objective test in evaluating the hearing threshold. It also helps in diagnosing retrocochlear lesions with suspected hearing loss or pathological speech development.

This procedure involves the study of electrical activities and responses of the brain to the sound and is beneficial for measuring the hearing ability of both adults and children.

Advantages of the BERA

In BERA electrodes are placed to the skin of the head and behind the ear which measure the receiving sound waves in the form of electrical signals capacity of the brain. A special head phone also can be used through which clicking sounds can be sent to the inner ear. Any impairment in the transmission of the signals indicates a problem associated with hearing.

The advantages of the BERA (Brainstem Evoked Response Audiometry) test include early diagnosis of hearing impairment, identification of causes of hearing impairment.
