A patient is having a tympanogram. What is the significance of this test?
|
|
A tympanogram, or impedance audiometry, measures middle ear muscle reflex to sound stimulation and compliance of the tympanic membrane by changing the air pressure in a sealed ear canal.

Explanation:
Detailed explanation-1: -Physics of the Tympanogram The tympanometer measures the “admittance” or “compliance” of the tympanic membrane while different pressures are being applied to the external ear canal. The compliance of the TM is measured in cubic centimeters, and the pressure in the ear canal is measured in decapascals (daPa).
