Diagnostic Audiologic Evaluation
It is important to note that there is a difference between a hearing screening and hearing evaluation. A hearing screening is often done at no charge for the client, and can quickly determine whether or not a a hearing loss exists. Once it is determined that a loss is present, it is important to see an audiologist or certified physician for a comprehensive hearing evaluation.
What to expect during your first visit?
At your first visit, you will fill out a case history form. Then you will meet with the audiologist who will ask you some questions about your hearing health. The audiologist will perform otoscopy, which is basically looking into your ear with a light to check for anything that might be present in the ear canal that could affect the results of the hearing test, or require referral to your doctor. Then the audiologist will perform immitance audiometry. This consists of taking a probe tip and placing it into the ear. The probe tip will change the pressure inside of the ear canal. Many clients report that it feels like “going up on an airplane.” The audiologist is making sure that the structures behind the eardrum, in the middle ear, are working properly. Finally, the audiologist will conduct a series of tests to asses:
- Whether there is a hearing loss
- The type of hearing loss
- The degree and configuration of hearing loss
- Evaluate Treatment options
As you can see, a full hearing evaluation is conducted using a test battery approach consisting of:
- Comprehensive Case History
- Otosocpic Examination
- Acoustic Immittance measures-
- Pure Tone Audiometry
- Bone Conduction Audiometry
- Speech Audiometry
