ABSTRACT
Objective The purpose of this study w as to obtain tympanometric norms in Sichuan young adult population and compare the results with data obtained for a non-Hispanic Caucasian population. Methods Normative values for peak compensated static acou stic admittance(Peak Ytm), acoustic equivalent volume(Vea), and tympanometric wi dth(TW) were obtained for 102 Sichuan young adults. Results Significant differences were fo und between Roup′s results and ous for Peak Ytm, Vea and TW. The present study showed lower Peak Ytm, smaller Vea and larger TW values overall. Gender differences were noted for Peak Ytm and Vea in Sichuan subjects . Male had higher Peak Ytm and bigger Vea values than female. Conclusion We should establish our own tympanometric norm s to guide our audiological clinical work.
