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…

Based on test-retest reliability and normal distribution characteristics, preferred methods for clinical estimation of resonant frequency were determined.

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).” produces a tympanometric curve that represents the compliance of the middle ear system, including the ear drum, as a function of the pressure applied to the eardrum (Figure 2). From the shape of the curve or the figures, one can also read the volume between the tip of the tympanometer and the eardrum and OBJECTIVE: To obtain tympanometric norms in Southern Chinese young adult population and compare the results with data obtained for a Caucasian population. DESIGN: Ear canal volume (Vea), tympanometric compensated static acoustic admittance (Peak Ytm), tympanometric width (TW) and tympanometric peak pressure (TPP) were obtained on 100 Southern Chinese young adults.

Tympanometric norms

Direction of ear-canal pressure change. 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. 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. 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 peak occurred during the tympanometric test. Stimulus tones of varying intensities at 500, 1000, 2000 or 4000 Hz are presented as short bursts.

However, little attention has been afforded to other potentialities such as the non-pathological Only measures of static acoustic admittance, ear canal volume, and tympanometric width/gradient compared to sex, age, and race specific normative data can be used to somewhat accurately diagnose middle ear pathology along with the use of other audiometric data (e.g.

Tympanometric peak pressure. 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).”

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 Objective To obtain tympanometric norms in Southern Chinese young adult population and compare the results with data obtained for a Caucasian population. Design Ear canal volume (Vea), tympanometric compensated static acoustic admittance (Peak Ytm), tympanometric width (TW) and tympanometric peak pressure (TPP) were obtained on 100 Southern Chinese young adults. these norms.

age specific tympanometric norms were developed in Caucasian population1-3 Wan & Wong (2002) used standard 226 Hz tympanometry to compare norms in Chinese young adults (ages 19 to 34) with the non-Hispanic Caucasian norms The purpose of this study is to establish the norms of standard and multiple- frequency tympanometry in Chinese young and older adults. The effects of age and 1 Nov 2004 2 However, for OME and AOM, pneumatic otoscopy is recommended as the primary tool for diagnosis of middle ear effusion. Other guidelines (10) The quantitative approach allows the development of tympanometric normative data which can be used as guidelines for ME screening.
