Impedance audiometry is an objective method based on the measurement of the pressure in the middle ear, stapedius reflexes, and tension of the tympanic membrane. It is one of the most common and most accurate methods for testing the middle ear.
The primary purpose of impedance audiometry is to determine the status of the tympanic membrane and middle ear via tympanometry.
The secondary purpose of this test is to evaluate acoustic reflex pathways,which include cranial nerves (CN) VII and VIII and the auditory brainstem.
