If you have been referred for a diagnostic audiological evaluation, it means that your hearing needs to be further examined. A diagnostic audiological 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 the hearing professional 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. Dimos 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 audiological 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 hearing professional with different information. A bone conduction test will help Dimos 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:
The hearing professional 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.
Specialized tests exist for infants and young children, as well as children and adults with developmental and cognitive impairments. These more-specialized tests allow the provider to test the auditory system when the patient is not able to actively participate in the tests or evaluation.
Word Discrimination Test and Quick Speech-in-Noise (QSIN) test
At Shuswap Hearing Clinic, led by our experienced provider Dimos, we understand the importance of conducting a diagnostic hearing evaluation whenever a hearing loss is suspected. This evaluation is the first step in identifying hearing loss and developing a treatment plan to enhance academic and social success.
As part of a comprehensive evaluation, additional tests such as the Word Discrimination Test and Quick Speech-in-Noise (QSIN) Test may be included to further assess your child’s hearing abilities.
After the evaluation, Dimos will take the time to review the results with you, interpret the findings, answer any questions you may have, provide information and referrals as needed, and begin planning for treatment, if indicated.
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 Dimos 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. Our provider Dimos believes 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 Dimos 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 audiological evaluation is a good chance to establish a relationship with your hearing professional. 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.
