Hearing Machine Expert Explains BERA Test For Infants

What is BERA Test And Why Is It Performed?

Hearing loss in children is difficult to detect at first. Hearing loss can all be exacerbated by speech, language, cognitive, social and emotional issues. As a result, it is preferable to conduct a hearing test on children as soon as possible, says a specialist of newborn baby hearing test.

When the auditory nerve can transmit sound impulses from the ear to the brain at a certain speed, this is referred to as healthy hearing. The BERA test can determine whether nerves transmit sound impulses to the brain and whether the sound delivery speed is within normal limits.

This hearing test can determine the type of abnormality, severity and location of the child’s hearing loss (inner ear or other parts).

BERA is also used in otoneurologic diagnosis to determine the hearing threshold. This is advantageous for patients who have unilateral or asymmetrical hearing loss (hearing nerve tumours, brain tumours, other nerve disorders, multiple sclerosis, etc.), says the expert of BERA test in Kolkata.

Procedure For The BERA Test

  • For children, this examination can be performed while they are awake, asleep, or under anaesthesia (although rarely).
  • During the BERA test procedure, electrodes will be placed on the patient’s head and behind the ear, and the patient will be exposed to various sounds via headphones. This test assesses brain electrical activity (EEG) changes in response to acoustic stimuli.
  • Hearing loss is indicated by abnormalities in the transmission of signals when sound is heard.
  • There is no risk of complications with this examination, it is painless and it does not necessitate any special preparation for the BERA test, says the specialist of newborn baby hearing test.

What Is The Purpose Of It?

BERA (brainstem evoked response audiometry) is an objective neurophysiological method for determining hearing thresholds and diagnosing retro-cochlear lesions.

What Exactly Is The BERA Test For Infants?

BERA (brainstem-evoked response audiometry) is a simple, non-invasive, objective test detecting hearing loss in children and neonates. It is useful as a screening test in newborns, infants and other difficult-to-test patients.

Is The BERA Test Reliable?

The Brain Stem Evoked Response Audiometry (BERA) is an objective test determining the subject’s approximate average hearing threshold level. It is a very reliable but time-consuming test for objectively evaluating an adult or child’s hearing threshold across all frequencies except low frequencies.
