No subjects in either group had a history of head trauma or otoscopic evidence of eardrum abnormalities. Two parameters, static admittance and tympanometric width, were derived from standard low-frequency tympanometry and two 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. Normative values for peak, compensated static acoustic admittance (Peak Ytm), acoustic equivalent volume (Vea), and tympanometric width (TW) were determined for 102 young adults with normal hearing. Relative to the Margolis and Heller normative values, significant differences… 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.

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).” Objective To obtain tympanometric norms in Southern Chinese young adult population and compare the results with data obtained for a Caucasian population.

Normative values for peak, compensated static acoustic admittance (Peak Ytm), acoustic equivalent volume (Vea), and tympanometric width (TW) were determined for 102 young adults with normal 2019-03-21 Tympanometric data were gathered on a clinical immittance machine, the Virtual 310 equipped with a high frequency option. Four of the parameters—static admittance (SA), tympanometric width (TW), tympanometric peak pressure (TPP), and ear-canal volume (ECV)—were measured automatically at a standard 226 Hz frequency. J – GR (Gradient) = A measure of the shape (width) of the tracing. A gradient greater than 150 daPa is often associated with a collection of fluid in the middle ear space.

Normative values for peak, compensated static acoustic admittance (Peak Y tm), acoustic equivalent volume (V ea), and tympanometric width (TW) were determined for 102 young adults with normal hearing.

53 normal hearing adults (26 females and 27 males) were tested with two commercially available middle-ear analyzer systems 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. 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 tympanometric variables. A significant effect of age was observed for admittance at the tympanic membrane and tympanometric width but not for tympanometric peak pressure and ear canal volume.Thus, a significant difference observed between neonates (M= 124.8, SD =35.24) and infants (M= 113.90, SD= 1.09), t (116) = 2.28, p Tympanometric norms that are applied clinically have not considered gender or race factors until these days. However, as previous studies have suggested, tympanometric measurements may depend on gender and race, 12) 13) 14) and therefore, tympanometric norms which is suited for Korean should be established. Objective: To obtain tympanometric norms in Southern Chinese young adult population and compare the results with data obtained for a Caucasian population.

In comparison, the ASHA (1990) protocol based on the tympanometric width and compensated admittance yielded a sensitivity of 81.5% and a specificity of 79%. In the group with middle-ear effusion having pure-tone air-conduction thresholds not exceeding 20 dB HL at 1000, 2000, and 4000 Hz, the sensitivity was 63% for the ASHA (1990) protocol versus 89.5% for the Silman et al. (1992) protocol.

Objectives: The present study used tympanometric parameters to evaluate application of the current norms in Caucasian and Chinese school-aged children. The goals of this study were 1) to establish normative tympanometric data for school-aged children; 2) to determine whether the results vary significantly between Caucasian and Chinese children, male and female children, and children and … tympanometric peak pressure, peak admittance at tympanic membrane, tympanometric width and -canal volume were recorded.
