Impedance audiometry. Impedance or immitance audiometry is an objective assessment method of the function of the middle ear. By increasing acoustic pressure in the external ear canal, impedance audiometry measures the sum of resistance which a sound wave encounters on its way through the middle ear to the cochlear receptor.

Results: The result of the impedance audiometry is tympanogram presenting values of the intensity of acoustic reflex on the frequencies 500 Hz, 1 kHz, 2 kHz, 4 kHz. Depending on the appearance and placement of the tympanometric curve middle ear is evaluated as standard (Type-A), total occlusion (Type-B) or partial occlusion (Type-C).

For impedance audiometry, a hermetic seal is obtained by inserting a probe tip in the external ear canal. The pressure in the enclosed cavity is varied from + 200 to − 200 mm H 2 O and the change in sound pressure level of a probe tone is graphed. This shows the movement of the middle ear system as pressure is varied.

The Different Types of Audiometry. Pure – Tone Audiometry (Air Conduction Test): This is the most common hearing test. With a pair of headphones, sounds go through your outer and middle ear to assess the auditory sensitivity. Bone Conduction Audiometry: Similar to the pure-tone audiometry test, but instead of headphones, a small device is ...

Impedance audiometry is done to determine the status of the tympanic membrane and middle ear via tympanometry. The test is also used to evaluate acoustic reflex pathways, which include cranial nerves (CN) VII and VIII and the auditory brainstem. In short, it is middle ear analysis.

losses were consistent with early noise-induced damage (Niskar et al., 1998; Niskar et al., 2001). Because of the alarming rate of possible noise-induced hearing loss in this subpopulation, and because hearing loss
Interpreting the tests – Audiogram and Tympanogram
https://northsideaudiology.com.au/interpreting-test-results/
Tympanogram: Interpreting impedance results. Tympanometry is a test of middle ear functioning. It looks at the flexibility (compliance) of the eardrum to changing air pressures, indicating how effectively sound is transmitted into the middle ear. This objective test also allows us to view the functioning of the Eustachian Tube, the upper ...
