The BERA Test, also known as ABR (Auditory Brainstem Response) Test or Brainstem Evoked Response Audiometry, is a highly reliable diagnostic procedure used to evaluate the working of the auditory nerve and brainstem. It measures electrical responses generated by the ear and transmitted to the brain in response to sound stimuli. For this test, small electrodes are placed on the scalp to record nerve activity without any pain or discomfort.
This test is especially useful in assessing hearing ability in newborns, infants, young children, and individuals unable to participate in behavioural hearing tests.

What Does a BERA Test Detect?
A BERA test helps in diagnosing and understanding several hearing-related conditions:
✔ 1. Type & Degree of Hearing Loss
The test identifies the presence of conductive, sensorineural, or mixed hearing loss, and helps determine sound threshold levels.
✔ 2. Brainstem & Auditory Pathway Function
It evaluates the functioning of the auditory nerve and brainstem to detect abnormalities, lesions, or tumours affecting sound transmission.
✔ 3. Auditory Neuropathy & Central Hearing Disorders
Conditions such as Auditory Neuropathy Spectrum Disorder (ANSD) and Central Auditory Processing Disorder (CAPD) can be identified through BERA.
✔ 4. Hearing Threshold Estimation
It measures the softest level of sound a person can hear, even if they cannot respond verbally.
✔ 5. Auditory Nerve Abnormalities
Nerve damage, compression, or delays in brainstem response can be detected accurately.
How Does a BERA Test Work?
The test follows a simple, non-invasive procedure:
Electrode placement on the scalp (forehead, behind the ears, neck).
Earphones deliver sound signals like clicks or tones.
Electrodes detect brain & nerve responses to sound within milliseconds.
Signals are amplified and averaged for clarity.
An audiologist analyses waveforms, latency, and amplitude to interpret hearing function.
The results appear as a graph waveform, which helps in determining the integrity of the auditory pathway.
BERA Test Preparation & Procedure
Preparation Before the Test
Inform the doctor about current medications.
Keep scalp clean and free of oil, lotions, or creams.
Wear comfortable clothing.
Infants/children may be made to sleep during the test—bring a bottle or favourite toy if needed.
Procedure During the Test
Patient lies down comfortably in a quiet room.
Electrodes are placed to record neural activity.
Sound is delivered to one ear at a time.
Patient must remain still and relaxed.
Test duration: 30–60 minutes on average.
It is safe, painless, and suitable for newborn hearing screening.
