Methods 　Included in this study were 58 pubermiddle aged Chinese with normal hearing threshold and with no ear diseases. Their tympanograms were determined in sound isolation room by AA222 Middle Ear Analyzer with a probe sound at 226 Hz . Results 　Tympanograms of this group of subj ects determined in this way were all shown A type , ac cording to the standard of J erger categorizing system , with a slightly less static compliance value than foreign ers. With a comparison between the subj ects of puber group and middleaged group , there were statistic dif ferences in the values of equivalent canal volum
