2008-11-01 · Li et al. investigated tympanometric norms in school-aged Chinese children. The authors, responding to an absence of normative values for tympanometric testing in Chinese pediatric populations, obtained normative data (for the four main tympanometric parameters) from a sample of 269 Chinese schoolchildren.

Tympanometric width norms

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. The combination of a large gradient (>150 daPa) and low compliance (<0.2 cc) is associated with a 95% or greater likelihood of a middle ear effusion. Classifying Tympanograms 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. J – GR (Gradient) = A measure of the shape (width) of the tracing.

Tympanometry is a test of middle ear functioning. It looks at the flexibility (compliance) of the eardrum to changing Tympanic peak pressure is the value on the horizontal axis of the tympanogram at which the peak occurs. This is used to estimate the middle-ear pressure, see 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 Conventional and Multi-Frequency Tympanometric Norms for Caucasian and ( number of ears), and TPP: (tympanometric peak pressure from admittance.

It is not a hearing test, but rather a measure of energy transmission through the middle ear.
