Diagnostic Audiologic Evaluation

If you have been referred for a diagnostic audiologic evaluation, it means that your hearing needs to be further examined. A diagnostic audiologic evaluation may be indicated for individuals who did not pass an initial hearing screening.

The evaluation is done to determine if a hearing loss is present and, if so, to detail the type and severity of the hearing loss. It also may provide insight into the cause of the hearing loss as well as provide guidance for our audiologist in making appropriate treatment recommendations - or referrals to other professionals.

What Tests Will Be Done?

The specific tests done during the evaluation will depend on the patient's age, symptoms and medical history. These various tests will determine the degree of hearing loss, the type of hearing loss and the conditions of the ear canal and middle ear. Our audiologist will also establish if the hearing loss is conductive (middle or outer ear problem) or sensorineural (inner ear problem or an issue with the auditory nerve and central auditory pathways).

At a minimum, a diagnostic audiologic evaluation includes pure-tone testing, bone conduction testing and speech testing.

Pure-Tone And Bone Conduction Testing

Pure-tone testing determines the quietest tones that a person can hear at different frequencies, both low and high. Bone conduction testing is similar to pure-tone, however, a different type of headset is used to provide the audiologist with different information. A bone conduction test will help our audiologist determine whether the loss is conductive in nature or sensorineural.

Speech testing:

A speech reception threshold (SRT) test is used to confirm the results of a pure-tone test. This test determines the lowest level of sound the patient can clearly identify words or speech.

Additional tests:

Our audiologist may also perform otoscopy (physical examination of the outer ear and, ear canal and eardrum) and tympanometry (test of the middle ear) to determine the health of the ear canal and the middle ear.

What Can I Expect During A Diagnostic Hearing Evaluation?

The evaluation will last about 20-30 minutes in length. You should also allow time for discussion with our audiologist to review test results and ask questions.

If the results indicate you need hearing aids, allow for sufficient time to discuss your options.

Don't be afraid to ask questions! You will want to be clear on any information you receive so that you can be an active participant in finding hearing solutions that work best for you and your lifestyle.
