Tympanometry provides useful quantitative information about the presence of fluid in the middle ear, mobility of the middle ear system, and ear canal volume. Its use has been recommended in Physics of the Tympanogram If you have a tympanometer in your office, youshould begin to learn how to use it to verify thepresence or absence of middle ear effusion. Thetympanometer can provide particularly useful informationif other diagnostic methods are not feasible, forexample, if one cannot get a seal when performingpneumatic otoscopy, or when visualization of… The purpose of this study was to reexamine the Margolis and Heller (1987) normative tympanometric data (also American Speech-Language-Hearing [ASHA], 1990 interim norms) using a strict control over subject age and gender. Normative values for peak, compensated static acoustic admittance (Peak Ytm), acoustic equivalent volume (Vea), and tympanometric width (TW) were determined for 102 young Tympanometric Peak Pressure/Middle Ear Pressure Tympanometric peak pressure (TTP) or middle ear pressure (MEP) is the ear canal pressure at which the peak of the tympanogram occurs (Margolis & Hunter, 2000). Static Compliance Static compliance (SC) “is the greatest amount of acoustic energy absorbed by the middle ear system (the “peak” of the tympanometric trace falls along the pressure axis. Middle ear pressure values ranging from +50 daPa to –200 daPa for children, and +50 daPa to –50 daPa for adults is generally considered normal.

Tympanometric data can be obtained by varying the air pressure in the ear canal in a positive to negative (+ to -) direction or in a negative to positive (- to +) direction. Current tympanometric norms have acknowledged the relevance of age as an influencing factor.
