What is an Audiological Evaluation?

Audiology is the study of hearing and hearing disorders. An audiological evaluation is used when a hearing loss is suspected to determine the type and degree of hearing loss in each ear. The evaluation consists of multiple tests that ensure an accurate diagnosis is achieved. This evaluation will provide information necessary to establish an individualized treatment program.

Adult Audiological Evaluation
An audiological evaluation consists of a number of different tests to accurately determine the presence of a hearing disorder.
Air Conduction
This test is completed in an acoustically controlled room.  The patient sits with earphones on while the tester presents tones at different frequencies and different intensity levels to find the softest sounds the person can hear.  This tests the entire auditory system (outer ear canal, middle ear, and inner ear).
Bone Conduction
This is similar to the air conduction test discussed above but it uses a bone oscillator placed behind the ear to stimulate the inner ear and bypass the middle ear. The same tones are presented to determine the softest sounds the person can hear. This test is used to determine if there is a problem with the middle ear.
Speech Recognition
Speech is used to determine how well a person can understand speech when presented at a comfortable level. Some people with a hearing loss will have difficulty understanding speech even when it is loud enough for them to hear.
Tympanometry and Acoustic Reflexes
A tympanogram is performed help determine the health of the middle ear.  This test can help determine if there is fluid present in the middle ear, which is common with young children. The acoustic reflex is an automatic response of the ear to loud sounds and helps protect the ear from damage when loud sounds are present.
Pediatric Audiological Evaluation
At our center we are equipped to test children as young as one year old.  The same tests that are used for adults are also used for children. The presentation of the test is adjusted to the child’s of ability.  Many of the tests are made into a game to keep the child’s attention while still obtaining information to make a diagnosis of a hearing problem.
Otoacoustic Emissions
Otoacoustic emissions is a test that evaluates the status of the inner ear. This test is often performed on a person when either a reliable hearing test cannot be obtained or to confirm results from a hearing test.  The test gives a simple, fast, and reliable measurement of the cochlear (inner ear) function.A probe tip is placed in the ear canal, the person sits quietly while they hear some tones, and the results are displayed on the computer screen. The test does not require a response from the person.
Hearing Screenings
Screening of hearing is simply determining the presence or absence of a hearing problem. This is often the first step in detecting hearing loss. We are available to go out in the community to screen children and adults. If your company or organization is planning a health fair and is interested in our services please contact us.  Our screening services are offered at no charge.
