Tympanometry and spectral gradient acoustic reflectometry (SG-AR) are adjunctive diagnostic tools to pneumatic otoscopy. The aim was to investigate the diagnostic accuracy and success rates of tympanometry and SG-AR performed by physicians and nurses. The study populations comprised 515 (I-II), 281 (III), and 156 (IV) outpatients (6-35 months).

However, its shape may vary from a rounded type B with a “pseudopeak” to a completely flat response. The aim of this study was to compare the characteristics of the B curve (maximum admittance, tympanometric peak pressure, and area under the curve) to the viscosity of the middle ear fluid and to the air-bone gap (ABG).

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. Tympanometry is an objective test of middle-ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear. It is not a measure of TM or middle ear mobility. It is an acoustic measure, measured by a microphone, as part of the ear canal probe,inserted into the ear The acoustic tests included tympanometric peak-compensated static admittance magnitude (SA) and tympanometric gradient at 226 Hz, and admittance-reflectance (YR) measurements from 0.5 to 8 kHz. The performance of individual, frequency-specific, YR test variables as predictors was assessed.

Tympanometric gradient

Tympanometric peak pressure (TTP) or middle ear pressure (MEP) is the ear canal pressure at which the Gradient “Tympanogram gradient is an objective measure that describes the steepness of the slope of the tympanogram near the peak” (Fowler & Shanks, 2002, p.182). 2007-11-01 Tympanometric width (also referred to as tympanometric gradient), refers to the width of tympanogram (in daPa) measured at one half the compensated static admittance (DeJonge, 1986; … Skip to main content. Intended for healthcare professionals Tympanometric gradient and width. What are the VBWC's admittance norms peak middle ear admittance (90th percentile) for adults? 0.3 - 1.7 mmho's (mL or cc) What are the VBWC's admittance norms peak middle ear admittance (90th percentile) for kids (2.8 - 5.8y/o)?

The acoustic tests included tympanometric peak-compensated static admittance magnitude (SA) and tympanometric gradient at 226 Hz, and admittance-reflectance (YR) measurements from 0.5 to 8 kHz.

1999-11-01 · It is not surprising that tympanometric gradient is a better predictor of the ME status than the acoustic admittance. Gradient provides a summary parameter of the 2 dimensions of a tympanogram, whereas the acoustic admittance represents only 1, the peak, ignoring the slope of the tympanogram before and after the peak.
