BERA Hearing Test or say Brainstem Evoked Response Audiometry or Auditory brain stem response or an ABR audiometry or BAER or Brainstem auditory evoked response audiometry in children with hearing loss and delayed speech is a neurophysiological method for the evaluation of the hearing threshold and diagnosing retro cochlear lessons. BERA is a hearing test in which sounds given through the ear. In BERA test child should be sedated first, after sleep Audiologist place electrodes through gel. BERA test will take 30 min after sleeping but in case of full audiological evaluation (ASSR, BERA, Tympanometry, OAE ) it will take 1 Hour. In BERA test sound will start at 90 dB and decreases 10 dB till 30 dB (normal hearing ). We see wave Vth for hearing if wave Vth not seen till 30dB means hearing problem is there.
