Abstract. After a review of the development of acoustic impedance measurements, the principles of tympanometry, static compliance and measurements of the middle ear reflexes are described. The interpretation of tympanometry is done by analyzing three essential features: pressure, amplitude and shape. The influence of high probe tones on the shape of the tympanogram and …

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. Using the results of this test we cannot directly assess auditory sensitivity, although results are …

Abstract. A flat tympanogram predicts a middle ear effusion in about 90% of cases. This paper describes how to perform tympanometry, some common problems when doing it and how to classify the curves in normal (type A), middle ear effusion (type B) or negative pressure (type C). The theoretical background of impedance audiometry is outlined. The stapedius reflex, …

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.
