Interpreting Tympanometry

A few useful terms to assist with understanding and interpreting tympanometry measurements:

Ear Canal Volume: An estimate of the volume of air medial to the probe.
Peak Pressure: The ear canal pressure at which the peak of the tympanogram occurs.
Static Compliance: The greatest amount of acoustic energy absorbed by the middle ear system.
Gradient: Objective measure that describes the steepness of the slope of the tympanogram near the peak.
