What This Test Is
BERA stands for brainstem evoked response audiometry. It is also widely known as auditory brainstem response (ABR) testing. Brief sound clicks are delivered through earphones while scalp sensors record responses along the auditory pathway and brainstem.
BERA is not a conversational hearing test in a booth alone. It provides electrophysiological information that a neurologist may use alongside clinical findings.
Why This Test Is Performed
BERA may help assess auditory pathway and brainstem responses when neurological questions remain after history and examination.
It is selected only when likely to add useful information. Ear, nose, and throat or audiology evaluation may still be needed for many hearing concerns.
When This Test May Be Considered
Not every ear symptom needs BERA. Your neurologist decides based on the clinical question.
- Selected neurological assessments of hearing pathways
- Evaluation of brainstem-related auditory responses when appropriate
- Supportive testing recommended after neurological consultation
- Other indications where objective auditory brainstem data may help
Preparation Guidance
- Follow clinic advice about rest and recent ear infections or illness
- Bring hearing aids and prior audiology or ENT reports if available
- Arrive with clean hair if scalp sensors will be applied
- Tell the team about ear surgery, perforated eardrum concerns, or severe discomfort with earphones
- Ask whether a quiet, still environment or light sedation protocols apply in special cases—only as directed by clinicians
What Happens During the Test
Sensors are placed on the scalp and earphones deliver click or tone stimuli. You rest quietly, often with eyes closed, while responses are averaged by the machine.
The test is generally painless. Staying relaxed and still improves recording quality. Tell staff if earphones are painful or if you feel unwell.
How Long It Takes
Timing varies with protocol, cooperation, and whether both ears need detailed study. Allow the appointment window advised by the clinic, which may be longer than a brief hearing screen.
Risks and Safety
BERA is generally low risk. Some people notice temporary earphone pressure discomfort or mild scalp paste messiness. Sound levels are set for diagnostic recording.
BERA does not replace emergency care for sudden neurological deficits, sudden severe hearing change with concerning features, or acute illness.
Results and Next Steps
Results describe waveform timing and presence along the auditory brainstem pathway. Interpretation requires clinical context and technical quality review.
- Discuss results with your neurologist
- Ask whether ENT or audiology follow-up is also recommended
- Clarify how findings affect the working diagnosis and next investigations
- Seek urgent care for sudden weakness, speech difficulty, or other stroke-like symptoms rather than waiting for routine results visits
Limitations
Middle-ear problems, excessive movement, technical noise, or severe peripheral hearing loss can limit recording quality. Waveform changes are not unique to one diagnosis.
Your neurologist explains what your BERA can support and which questions need other tests.
Frequently Asked Questions
Is BERA the same as a routine hearing test?
Not exactly. BERA/ABR records electrophysiological responses along the auditory pathway and brainstem. Standard audiometry still matters for many hearing questions.
Does BERA hurt?
No. You hear clicks through earphones while sensors record responses. Some people find earphones mildly uncomfortable but the test is not a painful procedure.
Why might a neurologist request BERA?
When the clinical question involves auditory pathway or brainstem responses that may refine neurological assessment. It is not used for every dizziness or ear complaint.
Can I wear hearing aids during the test?
Usually hearing aids are removed for earphone stimuli, but bring them and follow clinic instructions for your situation.
Is BERA safe for children?
When clinically indicated, paediatric protocols may be used. Cooperation and preparation needs differ by age and are explained by the clinical team.
What if the recording is technically limited?
Movement, ear conditions, or signal noise can reduce quality. Repeat testing or alternative evaluations may be advised.
When should I discuss BERA results?
Review them with your neurologist so findings are interpreted with your history, examination, and any ENT input. Do not self-diagnose from waveform labels alone.
