  2. Auditory Brainstem Response Testing(ABR) The Auditory Brainstem Response test can be used as a screening test for deafness or people with hearing loss in high-risk infants. Early diagnosis and rehabilitation will reduce disability in these children. The ABR is considered to be an exogenous response because it is fully dependent upon the external factors. Brainstem evoked response audiometry is a useful assessment technique of hearing. A major advantage of this procedure is its ability to test even infants.

  3. Click-Auditory Brainstem Response Testing(ABR) The sound of clicks alert the whole cochlear, it has been found that the ABR thresholds obtained by clicks match the behavioral thresholds only at high frequencies (2000-4000). The result concludes, and despite the fact that the click excites the entire cochlear partition, the ABR as recorded from the scalp represents activity from the cochlear region in between 2800-4000 Hz with less contribution from 2000 Hz region.

  4. ABR for Children Auditory Brainstem Response can also be used as a screening test in newborn hearing screening tests. Use of Electrodes:The electrodes are used to record BERA and always help to give proper output, It should be placed over the scalp, the scalp hair should he oil free. Use of BERA:Auditory brainstem response is a valuable objective measure of hearing.

  5. Conclusion Auditory Brainstem Response is a useful tool in identifying deafness in neonates. It can also be used as a screening tool for prior evaluation of deafness in high-risk infants. The ABR also gives a reasonable and accurate proper assessment of hearing threshold levels objectively when used in adults. When used with speech stimuli it helps in the identification of complex auditory disorders involving auditory processing areas of the brain.
