Diagnostic Audiologic Evaluation
A diagnostic hearing evaluation is the first step in determining your hearing capability. If you have a hearing loss, it will detail the amount, type and specifics of your specific loss. The diagnostic hearing evaluation will be performed by Dr. Shafer.
The diagnostic hearing evaluation consists of a variety of tests to determine the unique aspects of your hearing loss, as well as the level at which you can detect and understand speech. This evaluation can be conducted on people of any age, from newborn infants to seniors.
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. The 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 the audiologist determine whether the loss is conductive in nature or sensorineural.
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.
The 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 30-40 minutes in length. You should also allow time for discussion with the audiologist to review test results and ask questions.
If the results indicate you need hearing aids, allow for sufficient time to discuss your options.
It is recommended that you bring a family member with you to the evaluation appointment. Most audiologists agree that hearing loss is a family issue. It helps to have another supportive person at the appointment to help you understand the information and recommendations.
Before your appointment, a complete medical history will be completed and the audiologist will want to hear about any complaints you have about your hearing. They will pay special attention to any concerns you have about exposure to noise, tinnitus and balance problems. Make sure that you take a full list of any medications and supplements you are taking with you to your appointment.
The diagnostic audiologic evaluation is a good chance to establish a relationship with your audiologist. It helps to ask around for recommendations to audiologists in your area and find someone who listens carefully to your concerns. Above all, 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.
