Tympanometry is a type of hearing test that measures the movement of the eardrum in response to changes in air pressure. There are several different types of tympanometry tests that can be performed depending on the specific needs of the individual being tested.
Here are some of the Most Common Types:
- Static acoustic impedance test: This test measures the amount of air pressure needed to move the eardrum, and can help detect problems such as a blocked Eustachian tube or fluid buildup in the middle ear.
- Tympanometry with reflex testing: This test measures the eardrum’s movement in response to loud sounds, and can help identify problems with the auditory pathway.
- High-frequency tympanometry: This test measures the movement of the eardrum at high frequencies, which can help detect problems with the outer and middle ear.
- Wideband absorbance tympanometry: This test measures how much sound energy is absorbed by the middle ear, which can help identify problems with the middle ear, such as ossicular chain discontinuity or tympanic membrane perforation.
The specific type of tympanometry test that is performed will depend on the individual’s symptoms, medical history, and the suspected cause of their hearing problems. Your audiologist or hearing healthcare professional can help determine which type of tympanometry test is right for you.
