If you have been referred for a hearing evaluation, it means that your hearing needs to be further examined. A hearing 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 Instrument Specialist 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. The Hearing Instrument Specialist 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 hearing 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 Instrument Specialist with different information. A bone conduction test will help the Hearing Instrument Specialist 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 Instrument Specialist may also perform otoscopy (physical examination of the outer ear and, ear canal and eardrum).
What can I expect during a hearing evaluation?
The evaluation will last about 60 minutes in length. You should also allow time for discussion with the specialist 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 Hearing Instrument Specialists 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 Hearing Instrument Specialist 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 hearing evaluation is a good chance to establish a relationship with your Hearing Instrument Specialist. 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.
