Purpose of the Test

Evoked Response Audiometry (ERA) is a type of audiology test that measures the brain’s response to sound. It can help diagnose hearing problems or identify problems with the auditory nerve or brainstem.

When this test is required

ERA testing may be requested by a doctor or audiologist if a patient has symptoms of hearing loss or other auditory problems. It may also be used to monitor hearing function in people with certain medical conditions, such as multiple sclerosis or acoustic neuroma.

What the Test Detects

ERA testing measures the brain’s electrical activity in response to sound. The patient wears earphones and listens to a series of tones or clicks while electrodes attached to the scalp record the brain’s response.

Preparation for the Test

The patient may need to avoid caffeine or other stimulants for a certain period before the test. The doctor or audiologist will provide specific instructions on how to prepare for the test.

Sample Requirements

No sample is required for ERA testing. The test is non-invasive and painless.

Additional Notes

ERA testing is a non-invasive and painless procedure, but it can be time-consuming and may require the patient to sit still for an extended period. The doctor or audiologist will provide instructions on how to prepare for the test and what to expect during the procedure.
