Hearing Testing
Learn more about the types of hearing tests administered at Dr. Kane's office.
Audiogram: This testing is performed to evaluate suspected hearing loss and/or tinnitus (ringing in the ears). The audiogram helps to determine if the hearing loss is sensorineural, or if it is due to conductive factors. It also provides dignostic information about the conditions that cause hearing loss. An audiogram plots a picture of your hearing as it compares to normal hearing of sounds at different intensities (loudness) and frequencies (pitch) that make up the human voice when speaking at normal conversational levels.
Tympanogram:
Tympanometry is a test where air pressure in the ear canal 
is varied to test the condition and movement of the ear drum (tympanic membrane). This is useful in detecting disorders of the middle ear.The test begins with an inspection of the ear canal with an otoscope ensuring that there is a clear path to the ear drum. Then, a device is inserted in the ear that changes the pressure, produces a pure tone, and measures the body's responses to the sound at different pressures.
Videonystagmography: This test helps to determine reasons for dizziness or unsteadiness. It can help determine the degree and location of a balance dysfunction. To perform the test, video goggles are placed on the face. The patient is asked to follow lights on a bar. His or her balance system is gently stimulated. This is accomplished by changing their position and by introducing cool and warm air into their ears. A computer is used to analyze their responses.
