ASSR test

👂 ASSR Test (Auditory Steady-State Response) | Precise Hearing Evaluation for All Ages

The ASSR test, or Auditory Steady-State Response test, offers a non-invasive and highly accurate way to measure how the brain responds to sound. Audiologists use it to determine hearing thresholds at different frequencies, making it ideal for patients who can’t complete traditional hearing tests—such as newborns, infants, or individuals with developmental delays.

Unlike the ABR test, which gives a general picture of hearing ability, the ASSR provides frequency-specific results. Therefore, it plays a critical role in planning treatments like hearing aid fitting or cochlear implant candidacy.

✅ Why Doctors Recommend the ASSR Test

• It measures hearing thresholds at multiple frequencies with great precision.

• In addition, it allows audiologists to test both ears at the same time.

• The test suits non-responsive or sedated patients, such as infants or young children.

• Moreover, it offers valuable data for hearing aid programming.

• Many professionals combine ASSR with ABR to improve diagnostic accuracy.

🧪 How the ASSR Test Works

1. The audiologist places small electrodes on the patient’s head.

2. The patient wears earphones that play steady tones with varying frequencies and modulations.

3. These sounds trigger continuous brain responses, which the system monitors and records.

4. The audiologist analyzes these responses to determine the patient’s hearing sensitivity.

5. As a result, they can accurately classify hearing loss as mild, moderate, severe, or profound.

Since the patient doesn’t need to respond, works especially well during natural sleep or under light sedation.
