Current tympanometric norms have acknowledged the relevance of age as an influencing factor. However, little attention has been afforded to other potentialities such as the non-pathological effects of gender, ear asymmetry, and racial heritage. This study aimed to examine normative tympanometric findings in a large sample of Chinese schoolchildren. Using a Madsen 901 Middle Ear Analyzer, data was collected from 269 children (538 ears), ranging in age from 6.2 12.7 years (mean = 9.4 years, SD = 1.7), in Jiangsu province. Descriptive statistics were calculated for the parameters of equivalent ear canal volume (chi = 1.03, SD = 0.25, 90% = 0.68 1.46), peak compensated static acoustic admittance (chi = 0.58, SD = 0.34, 90%=0.26 1.13), tympanometric width (chi = 112, SD = 36, 90% = 62-156), and peak pressure (chi = -25, SD = 30, 90% = -85 -/+ 10). Statistically significant ear asymmetry and grade/age effects were established, although differences found were minor. In comparison with past studies in Caucasian paediatric populations, the Chinese normative data displayed minimal disparities.
