If you suffer from hearing loss or other hearing and balance related conditions, you may benefit from an audiologic evaluation. These comprehensive diagnostic exams can determine the cause, severity and best treatment option for these conditions in infants, children and adults.
Some of the common types of audiologic tests for older children and adults include:
- Diagnostic Audiogram - An audiogram uses sounds of specific frequencies and intensity levels to determine what a person can hear in each ear. The sounds are heard through headphones and the patient is asked to identify each time they hear a sound and in which ear. The sounds will become lower and lower to determine the level at which a patient can barely hear. An audiogram may also include speech in the form of two-syllable words to determine how well a patient can comprehend what is being heard. Normal results allow for a patient to hear a normal speaking voice, whisper and ticking of a watch.
- Play Audiometry - Play audiometry is a modified version of the diagnostic audiogram, sometimes chosen instead when working with preschool and school age children. The sounds are heard through headphones, but rather than raising a hand to indicate hearing a sound, the child places a toy in a container.
- Tympanometry - Tympanometry examines and diagnoses the middle ear by varying air pressure in the ear canal to see how the ear responds. A probe is inserted into the ear to change the air pressure, produce a tone and then measure the responses. The patient may not speak, move or swallow during the test because these actions can affect the ear pressure. Tympanometry measures the functionality of the ear drum or tympanic membrane. Abnormal results may be the result of fluid in the middle ear, perforated ear drum or impacted ear wax.
