Diagnostic Hearing Evaluation
A diagnostic hearing evaluation is the first step in determining your hearing capability. If you have a hearing loss, it will detail the extent, type, and specifics of your particular hearing loss. The diagnostic hearing evaluation will be performed by an audiologist, usually in his or her office, using equipment called an audiometer.
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 adults.
A diagnostic hearing evaluation may include the following tests:
- Air conduction testing
- Bone conduction testing
- Speech testing
- Distortion product otoacoustic emissions (DPOAE) testing
- Tympanometry or acoustic immittance testing
The diagnostic hearing evaluation is covered by most health insurance policies, though you may need a referral from your primary care physician to quality for coverage.
Why a Diagnostic Hearing Evaluation is Important
Diagnostic hearing evaluations identify hearing loss, and give your audiologist important information to help determine the best course of action for treatment. Some types of hearing loss can be treated medically or surgically, so it’s important that these types of hearing losses be ruled out before hearing aids or other treatments are considered.
If it is determined that you could benefit from hearing aids, the diagnostic hearing evaluation helps your audiologist know which hearing aids will be most appropriate for your needs.
What Can I Expect During a Diagnostic Hearing Evaluation?
The evaluation will probably last about 30 to 40 minutes in length. You should also allow for time for discussion with the audiologist to review test results, and ask questions.
If the determination is made that you need hearing aids, an appointment will be made to discuss your individual needs.
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. He or she 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.
