Definition. The maximum compliance (mobility) of the middle ear system (i.e., the greatest amount of acoustic energy absorbed by the middle ear system (the vertical peak of the tympanogram tracing). [from NCI] Equivalent ear canal volume, Static compensated acoustic admittance, Tympanometric peak pressure, and Tympanometric width/gradient Term -Prior to performing tympanometric testing, gorical assignments (eg, tympanometric gradient, pressure at minimum sound reflectance, tympano gram type) for the function relating tympanic mem brane (TM) soundreflectance to appliedexternalca nal pressure.IO-12,15-19 Certain of these descriptors were reported to reflect the functional integrity of The acoustic tests included tympanometric peak-compensated static admittance magnitude (SA) and tympanometric gradient at 226 Hz, and admittancereflectance (YR) measurements from 0.5 to 8 kHz. The performance of individual, frequencyspecific, YR test variables as predictors was assessed.

Ear Canal Volume Averages • Adults: 0.6cc to 1.5cc • Children 3 – 5yrs: 0.4cc to 1.0cc Normal tympanometric gradient: a comparison of three methods. @article{Jonge1986NormalTG, title={Normal tympanometric gradient: a comparison of three methods.}, author={R. de Jonge}, journal={Audiology : official organ of the International Society of Audiology}, year={1986}, volume={25 4-5}, pages={ 299-308 } } Tympanometric peak pressure, also known as middle ear pressure, is the ear canal pressure at which the peak of the tympanogram occurs [2]. 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).” Gradient Tympanometry is an acoustic evaluation used to evaluate the condition of the middle ear eardrum and the conduction bones by creating variations of air pressure in the ear canal.

This tympanogram is a normal tympanogram. The shape is type A. In looking at the results, it has normal mobility, ECV, compliance, pressure and gradient.

Trois mesures de gradient onl été déterminérs pour chaque tympanogramme: Gdif, G ratio et G dP. Chaque mesure de gradient a été évaluée pour son utilité éventuelle dans la discrimination entre oreilles avec et sans effusion. Tympanometric gradient is a quantitative expression of the shape of a tympanogram in the vicinity of the peak. Previous work suggests that gradient measures may be diagnostically and prognostically useful in the assessment and management of middle ear disease.

Tympanometry is an objective test of middle-ear function. The tympanometer measures the “admittance” or “compliance” of the tympanic membrane while different pressures are being applied to the external ear canal. The compliance of the TM is measured in cubic centimeters, and the pressure in the ear canal is measured in decapascals (daPa).

The characteristics of high frequency (1000 Hz) acoustic admittance results obtained from normal neonates were described in this study. Participants were 170 healthy neonates (96 boys and 74 girls) aged between 1 and 6 days (mean = 3.26 days, SD = 0.92).

2007-09-20 · The tympanometric gradient was obtained from a tympanogram done on each ear. A multivariate statistic was used to compare the emission SNR from both methods. A χ 2 statistic was used to compare the pass/refer rates from both methods. The agreement between the pass/refer rates from the OAE screens and from the tympanometric gradient were compared.
