About
This test records how the hearing nerve and brain pathways respond to sound using small sensors placed on the head and ears. It is painless, safe, and often performed while the patient is asleep or resting quietly. The ABR/BERA test is especially useful for infants, young children, or individuals who cannot participate in regular hearing tests, as it does not require active responses. It helps in detecting hearing loss, estimating hearing thresholds, and identifying problems in the auditory nerve or brain pathways. The procedure typically takes about 45 minutes to 2 hours, and may take slightly longer in children who need extra time to remain calm or asleep. This test is also valuable in cases of suspected auditory neuropathy or retrocochlear disorders, providing critical information for diagnosis and treatment planning.
