Accuracies of ambient and tympanometric wideband absorbance did not differ. pressure, physical volume, compliance, and gradient (tympanometric width). The variables containing the numeric data for these latter measurements (AUXTMEPR, AUXTMEPL, AUXTPVR, AUXTPVL, AUXTCOMR, AUXTCOML, AUXTWIDR, and AUXTWIDL) are located in the separately released NHANES 2001-2002 Audiometric Examination data file (AUX_B).

Static compliance. Onusko [3] defines static compliance as “the greatest amount of acoustic energy absorbed by the middle ear system (the vertical peak of the tympanic tracing).” Equivalent ear canal volume, Static compensated acoustic admittance, Tympanometric peak pressure, and Tympanometric width/gradient Term -Prior to performing tympanometric testing, frequencies, and narrowed tympanometric width (TW) (Feldman, 1974; Osguthorpe, 1986). These changes result from the loss of stiffness that accompanies loss of connective tissue within the middle layer of the TM. Along with increased admittance and decreased width, the resonant frequency is also often decreased when mea-sured with MFT. Two parameters, static admittance and tympanometric width, were derived from standard low-frequency tympanometry and two parameters, resonant frequency and frequency corresponding to admittance phase angle of 45 degrees (F45 degrees), were derived from multifrequency tympanometry. Results: Differences between normal and otosclerotic ears were DOI: 10.4103/indianjotol.indianjotol_120_19 Corpus ID: 229717272.

Values Range of Tympanometric Gradient in Otitis Media With Effusion The authors found the values range from 0.01 to 1.52 mL gradients (mean least value 0.15 mL) in adults and the values range from 0.01 to 0.93 mL gradients (mean least value 0.10 mL) in children in the presence of otitis media with effusion.

The remaining two parameters, Tympanometric Width. Evaluation of tympanometric width, often termed tympanometric gradient, Tympanometric width is a measure of the width of the tympanogram measured at half of the static admittance from the peak to the admittance at +200 daPa.
