More About Us / Audiological Tests We Perform
Audiological Evaluation This is commonly known as a hearing test. We conduct a series of tests that provide us with more information regarding your ear’s response to pure tone sounds as well as checking to see how your ear processes speech sounds. The evaluation can take anywhere from 15 to 30 minutes. The result is recorded as a characteristic audiogram curve. An audiogram is a graphic representation of your hearing ability. During a hearing test, your hearing is checked across a spectrum of frequencies.
Tympanometry This test examines the function of the middle-ear and mobility of the ear drum. It measures the impedance of the middle ear to sound by using an airtight seal and a microphone to deliver sound into the ear canal. The amount of sound that is absorbed from the middle ear is measured at the microphone at normal, positive, and negative air pressures. Tympanometry is useful in identifying middle-ear effusions.
Otoacoustic Emmission (OAE) This specialized hearing test takes about 10 to 15 minutes and gives information about the hearing organ itself. We let you listen to several different sounds and then measure the reflection of those sounds from your inner ear. Further information on this test can be located under Audiology Screening Tests.
Electronystagmograph (ENG) This test is also called an ENG and is used on patients who are having problems with dizziness, balance or disequilibrium. It is typically completed on adults and takes 90 to 120 minutes. We will talk with you ahead of time about medications to stop and food to eat before the test. During the test we will have you stand in various positions to test your overall balance. Then observe eye movements while stimulating the balance organ by putting warm and cool air in your ear and having you follow simple light patterns with your eyes. This testing can give a short-term sensation of motion or spinning for some people.
