Focus Keyword: BERA Test
Introduction
Hearing plays a vital role in speech development, communication, learning, and overall quality of life. When hearing problems are detected early, appropriate treatment and rehabilitation can begin at the right time, reducing the risk of speech and language delays. However, many babies, young children, and even some adults are unable to participate in conventional hearing tests because they cannot respond reliably. In such cases, doctors recommend the BERA Test (Brainstem Evoked Response Audiometry).
The Brainstem Evoked Response Audiometry is an advanced, objective hearing assessment that measures how the hearing nerve and brainstem respond to sound. Unlike regular hearing tests, this procedure does not require the patient to speak, press a button, or raise a hand after hearing a sound. This makes it one of the most accurate hearing tests for newborn babies, infants, children with developmental delays, and adults with suspected auditory nerve disorders.
At SoundCare Speech & Hearing Centre, we are committed to providing accurate hearing assessments, expert audiology services, and personalized hearing care. In this guide, you’ll learn everything you need to know about the Brainstem Evoked Response Audiometry, including its purpose, procedure, benefits, preparation, and who should undergo this important hearing examination.
What is a BERA Test?
BERA (Brainstem Evoked Response Audiometry) is a specialized diagnostic hearing test that evaluates the electrical activity generated by the auditory nerve and brainstem when sound is presented through earphones.
Small electrodes are placed on the patient’s forehead and behind the ears to record these electrical signals. Since the patient is not required to respond actively, the BERA Test is considered an objective hearing test.
It helps audiologists determine whether sound is reaching the hearing nerve properly and whether the brainstem is processing those sounds normally.
Full Form of Brainstem Evoked Response Audiometry
BERA = Brainstem Evoked Response Audiometry
The test is also known as:
- Auditory Brainstem Response (ABR) Test
- Brainstem Hearing Test
- Objective Hearing Assessment
- Evoked Response Audiometry
Why is a BERA Test Performed?
Doctors recommend a Brainstem Evoked Response Audiometry when they need a reliable assessment of hearing, especially if traditional hearing tests cannot be performed accurately.
The test helps diagnose:
- Congenital hearing loss
- Hearing impairment in newborns
- Delayed speech due to hearing loss
- Auditory nerve disorders
- Brainstem abnormalities
- Sensorineural hearing loss
- Auditory Neuropathy Spectrum Disorder (ANSD)
- Unexplained hearing difficulties
Early diagnosis allows treatment to begin as soon as possible, improving speech and language development, particularly in young children.
Who Should Undergo a BERA Test?
A BERA Test is suitable for people of all ages but is especially recommended for:
Newborn Babies
Babies who do not pass their newborn hearing screening should undergo a Brainstem Evoked Response Audiometry to confirm whether hearing loss is present.
Infants and Young Children
Children who are too young to respond during standard hearing tests benefit greatly from this objective assessment.
Children with Speech Delay
If a child is not speaking according to developmental milestones, hearing loss may be a contributing factor. A BERA Test helps identify hearing issues that could affect speech and language development.
Adults
Adults experiencing unexplained hearing loss, tinnitus, dizziness, or suspected auditory nerve disorders may also require this test.
High-Risk Individuals
People with a family history of hearing loss, premature birth, birth complications, or neurological conditions may be advised to undergo a BERA Test.
How is the BBrainstem Evoked Response Audiometry Performed?
The BERA Test is simple, painless, and completely non-invasive.
The procedure generally includes the following steps:
- The patient is asked to lie comfortably in a quiet room.
- Small recording electrodes are attached to the forehead and behind each ear.
- Soft earphones are placed in the ears.
- Clicking sounds or tone bursts are played through the earphones.
- The electrodes record the electrical responses generated by the auditory nerve and brainstem.
- The audiologist analyzes these waveforms to determine hearing sensitivity and nerve function.
The patient does not need to respond verbally or physically during the test.
How Long Does a BERA Test Take?
The duration depends on the patient’s age and level of cooperation.
- Adults: 20–45 minutes
- Children: 30–60 minutes
- Babies: 30–60 minutes
In some cases, additional testing may slightly increase the examination time.
Does My Baby Need to Sleep During the Test?
Yes. Babies generally need to remain asleep or very calm during the examination because movement can interfere with the recordings.
Parents are usually advised to feed the baby before the appointment so they naturally fall asleep during the procedure.
In certain situations, mild sedation may be recommended under medical supervision.
Is the Brainstem Evoked Response Audiometry Painful?
No. The Brainstem Evoked Response Audiometry is completely painless and safe.
The electrodes simply record electrical signals generated naturally by the body—they do not deliver electricity into the body. Patients usually feel nothing more than the placement of small adhesive sensors on the skin.
What Can a Brainstem Evoked Response Audiometry Detect?
The BERA Test helps diagnose several hearing-related conditions, including:
- Mild to profound hearing loss
- Sensorineural hearing loss
- Hearing nerve dysfunction
- Auditory Neuropathy Spectrum Disorder (ANSD)
- Brainstem abnormalities
- Acoustic neuroma (in selected cases)
- Delayed neural transmission in the auditory pathway
It is considered one of the most reliable tests for evaluating the hearing pathway from the ear to the brainstem.
Advantages of the BERA Test
The BERA Test offers several important benefits:
- Accurate and objective hearing assessment
- Suitable for newborn babies and infants
- No patient response required
- Completely safe and painless
- Detects hearing loss at an early stage
- Helps identify auditory nerve disorders
- Supports early speech and language intervention
- Useful for patients with developmental disabilities
- Highly reliable diagnostic results
BERA Test vs PTA Test
Many people confuse the BERA Test with the Pure Tone Audiometry (PTA) Test, but they serve different purposes.
| Feature | BERA Test | PTA Test |
|---|---|---|
| Patient Response | Not Required | Required |
| Suitable for Babies | Yes | No |
| Objective Test | Yes | No |
| Measures Brainstem Response | Yes | No |
| Best for Young Children | Yes | Limited |
Your audiologist will recommend the most appropriate hearing test based on your age and symptoms.
How to Prepare for a Brainstem Evoked Response Audiometry?
Proper preparation helps ensure accurate test results.
Before the appointment:
- Wash your hair thoroughly.
- Avoid applying hair oil, cream, or gel.
- Feed babies before arriving.
- Bring previous hearing reports if available.
- Dress infants comfortably.
- Follow your audiologist’s instructions if sedation is advised.
Is BERA Better Than OAE?
The OAE (Otoacoustic Emissions) Test and the BERA Test are different but complementary hearing assessments.
- Checks the function of the inner ear (cochlea).
- Often used as the first newborn hearing screening test.
- Evaluates the auditory nerve and brainstem.
- Confirms hearing loss when OAE results are abnormal or inconclusive.
Many hospitals perform an OAE test first and recommend a BERA Test if further evaluation is needed.
Is the Brainstem Evoked Response Audiometry Safe?
Yes. Brainstem Evoked Response Audiometry has been used worldwide for decades and is considered extremely safe for:
- Newborn babies
- Infants
- Children
- Adults
- Senior citizens
There is no radiation, no injections, and no electric current passed into the body.
