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 auditory pathways and the reflex contraction …

Tympanometry is a testing methodology that is used to evaluate the function of the middle ear. It provides a graphic representation of the relationship of air pressure in the external ear canal to impedance (resistance to movement) of the ear drum and middle ear system. This impedance measurement examines the acoustic resistance of the middle ear.

Tympanometry also called tympanometry impedance testing, is a clinical test measuring tympanic membrane mobility to detect problems in the middle ear and is graphically displayed as a tympanogram. Tympanometry provides information on acoustic admittance, which is a measure of the ease with which energy flows through the middle ear system, and impedance, …
Tympanometry - ASHA
https://www.asha.org/policy/RP1988-00027/
Tympanometry is a measurement of the input impedance or admittance of the middle-ear transmission system. The acoustic energy that flows into the system can be measured but not how much energy is transmitted through the system.
