Diagnostic Audiologic Evaluation
Tests and evaluations are different for every individual based on their age and hearing loss severity. Getting the right treatment is only possible after past and present health data is collected. After results are found, Advanced Hearing of Brighton communicates with patients about the best course of action for treatment.
Diagnostic audiologic evaluation
The evaluation uses several tests to find out the severity of hearing loss in both ears. It works for all ages and is a common approach to finding the right treatment. Current and past medical history will impact the type of tests used.
Patients that are referred from other screenings will have relevant data on file to help with testing accuracy. An examination is always in-depth and draws its conclusion based on the current data provided. Having an understanding of your diagnosis is an important part of a successful evaluation. Without this data, there are a few inconsistencies that audiologists have to work with when recommending treatment.
Pure-tone, bone conduction and speech tests are the most common methods used when diagnosing hearing problems. Pure-tone tests the hearing capabilities of ears by sending random beeps through headphones. The wearer then identifies which side the sound came from. It is a simple yet effective way to test hearing severity.
Speech testing evaluates how well an individual listens to and repeats words. Children with abnormal hearing may develop learning disabilities tied to their inability to comprehend information. Speech testing uses word recognition in clinic created environments. These are situations created to replicate everyday sounds and conversations to test the limit of speech recognition.
When wax or fluid is present in the ears, an audiologist will use bone conduction testing. A small device is placed behind the ear so that the test can proceed. Sound is sent through so that it vibrates the skull, directly interacting with the inner ear. This skips any problems with the middle or outer ear that prevent normal testing from proceeding.
Auditory brainstem response (ABR) and otoacoustic emissions (OAE) are two other test types that your audiologist may consider. ABR tests how well the outer, middle and inner ear react to one another. OEA is similar, but measures the strength of the reaction when the inner ear is active.
