Brainstem Evoked Response Audiometry (BERA) is a test that assesses the hearing threshold by analyzing the brain's electrical activity in response to sound. This test helps to detect hearing impairment, especially in newborns and individuals unable to cooperate during traditional hearing tests.
BERA testing plays an essential role in diagnosing neurological conditions, such as retro-cochlear lesions. It evaluates the auditory pathways from the ear to the brainstem, offering insight into nerve damage or other related issues.
Otoacoustic Emissions (OAE) testing, including Transient Evoked OAE (TEOAE) and Distortion Product OAE (DPOAE), assesses the cochlea's function by detecting sounds generated by the inner ear in response to stimuli. This test is widely used for hearing screening in infants and young children.
Late Latency Response (LLR) testing evaluates the brain's response to auditory stimuli, including both tone and speech sounds. This test helps to diagnose auditory processing disorders and provides valuable information on central auditory pathways.
Speech Auditory Brainstem Response (Speech ABR) is a specialized test that evaluates how the brainstem processes speech sounds. It is particularly useful in diagnosing speech perception disorders, auditory neuropathy, and other auditory processing issues.
