Diagnostic Audiologic Evaluation

What is it?

The diagnostic auditory evaluation (or hearing test) is performed by the Audiologist to determine the type, degree, and severity of your hearing loss. This test provides the Audiologist with valuable information needed to help make the best recommendation for your hearing needs. The hearing test is only one of many factors that helps the Audiologist determine if a hearing aid or alternate form of treatment is needed based on your results.

How it is performed?

The hearing test is performed inside a soundproof booth. Without a soundproof booth available, external noise in the office, phones, music, and outside traffic noise could affect your test results.

Listening through headphones, you will push a button each time you hear, or think you hear, a tone at multiple frequencies. The Audiologist will test both ears to determine if your hearing is equal or not.

After the pure tone testing, speech testing called Speech Reception Threshold and Word Recognition will be performed. The Speech Reception Threshold test records the softest level that you can hear speech. The Word Recognition test records a percentage of how well you can understand speech at loud enough speech levels. These results provide the Audiologist with vital information regarding how well your brain is interpreting and distinguishing speech.

How long does it take?

The diagnostic auditory evaluation usually lasts about 20-30 minutes.

Tympanometry:

What is it?

Tympanometry is a very useful test we administer to record the integrity of your eardrum, your eustachian tube, the bones of your middle ear, as well as the middle ear space. This information tells your Audiologist how well your middle ear is functioning and can help rule out any middle ear problems or abnormalities.

How it is performed?

An air-tight seal is achieved using an ear tip on a device called a tympanometer. You will feel a momentary change of pressure in the ear accompanied by a low frequency hum.

How long does it take?

The test takes several seconds in each ear. It is painless.

Acoustic Reflex Thresholds:

What is it?

By presenting a loud stimulus, the contraction of the stapedius muscle is measured. The stapedius muscle in the ear helps to protect our ears from loud sounds.

How it is performed?

With an air-tight seal in your ear, you will hear beeps which become louder. Whenever the stapedius muscle contracts, the loudness progression will stop. The equipment is automatic, and the contraction of the muscle is automatic. You will simply stay still while testing is occurring.

How long does it take?

The test takes several seconds in each ear. It is painless.
