Introduction

Hearing plays a crucial role in communication and overall quality of life. When it comes to diagnosing hearing issues, especially in infants or individuals who cannot respond actively during hearing tests, the Auditory Steady State Response Test (ASSR) stands out as a modern and precise solution. This test helps audiologists determine the degree and type of hearing loss through advanced technology that measures brainwave responses to sound.

In this guide, we’ll explain what the Auditory Steady State Response Test is, how it works, who needs it, what to expect during the procedure, and the assr test price in clinics and hospitals.

What Is the Auditory Steady State Response Test?

The Auditory Steady State Response Test (ASSR) is a computer-based hearing test that records brain responses to repetitive auditory stimuli, such as tones or clicks. It uses electrodes placed on the scalp to measure how the brain reacts to these sounds.

Unlike traditional hearing tests, ASSR does not require any response from the patient. This makes it ideal for newborns, children, or adults who cannot cooperate with behavioral tests due to medical or developmental conditions.

The results of this test help audiologists identify the degree of hearing loss—whether it is mild, moderate, or severe—and assist in selecting suitable hearing aids or cochlear implants.

How Does the ASSR Test Work?

The Auditory Steady State Response Test uses special electrodes attached to the patient’s head and behind the ears. The electrodes detect the brain’s electrical activity when specific sounds are played through headphones.

Here’s what typically happens during the test:

1. Preparation: The skin where electrodes are placed is cleaned to ensure accurate readings.

2. Placement: Electrodes are attached to the scalp and connected to a computer.

3. Sound Stimulation: A series of tones at different frequencies and intensities are played.

4. Recording: The computer records brainwave responses to these tones.

5. Analysis: Audiologists analyze the responses to determine hearing thresholds.

The test is non-invasive, painless, and usually takes about 30–60 minutes depending on the number of frequencies tested.

Who Needs an Auditory Steady State Response Test?

The ASSR test is recommended for:

• Newborns and infants: As part of early hearing screening.

• Children: Who cannot respond consistently in traditional hearing tests.

• Adults with disabilities: Who find behavioral hearing tests challenging.

• Patients with suspected severe hearing loss: To obtain accurate thresholds for hearing aid fitting.

Benefits of the ASSR Test

• Objective and accurate results: No need for patient feedback.

• Useful for all ages: Especially effective for infants and non-cooperative patients.

• Assists in hearing aid fitting: Provides frequency-specific hearing data.

• Comfortable and safe: Non-invasive and painless.

ASSR Test Price

The assr test price varies depending on the location, type of facility, and equipment used. On average, the cost ranges between PKR 7,000 to PKR 15,000 in Pakistan and $40 to $150 internationally.

Private hospitals and specialized hearing centers may charge slightly higher due to advanced diagnostic technology and experienced audiologists. Always check with your local audiology clinic for the most accurate pricing.

Factors affecting the assr test price include:

• Type of testing equipment used

• Experience of the audiologist

• Number of frequencies tested

• Whether it’s part of a full hearing evaluation package

Preparing for the Test

You don’t need any special preparation for an Auditory Steady State Response Test. However:

• Make sure the patient is relaxed or asleep (infants often tested while sleeping).

• Avoid applying lotions or oils on the head before the test.

• Follow any instructions provided by your audiologist.

Frequently Asked Questions (FAQs)

1. Is the Auditory Steady State Response Test safe?
Yes, the test is completely safe, painless, and non-invasive. It only measures brainwave activity and does not emit any harmful energy.

2. Can adults take the ASSR test?
Absolutely. While it’s commonly used for children, adults who can’t participate in standard hearing tests can also undergo ASSR testing.

3. How long does the ASSR test take?
The test usually takes 30–60 minutes, depending on the number of frequencies tested.

4. Is fasting required before the test?
No, fasting is not required. However, ensure the patient is well-rested or asleep for accurate results.

5. How accurate is the ASSR test?
The Auditory Steady State Response Test is highly accurate and provides detailed, frequency-specific hearing thresholds, which are essential for hearing aid programming.

Conclusion

The Auditory Steady State Response Test is a modern, reliable, and non-invasive way to assess hearing ability—especially in newborns, children, or individuals unable to perform traditional hearing tests. With its advanced accuracy and ability to measure detailed hearing thresholds, it’s an essential part of early hearing diagnosis and management.

While the assr test price may vary, the benefits of early detection and proper treatment of hearing loss far outweigh the cost. If you or your child is experiencing hearing difficulties, consult an audiologist today to learn more about this valuable diagnostic test.
