摘　　要：本文对406例儿童作声阻抗测试。测试结果,A 型鼓室图226例,其中124例声反射阈值在正常范围内,142例声反射阈值不是提高就是消失,占全部受检者的65.51%。B 型27例,占6.65%,其声反射全部消失。C 型83例和As 型29例,前者占20.44%,后者占7.14%,均发现少数几耳或某一频率,出现声反射阈值提高。作者认为,声阻抗测试在临床上只能作为听力学方面的一种重要的辅助诊断工具。This article reports the results of measurement of acoustic impedance in 406children.Children with Tympanogram Type A were 266(65.5%),of whom 124 hadnormal acoustic reflex thresholds (ART)and the other 142 had their ARTs eitherenhanced or lost 27 (6.65%) children with Tympanogram Type B had no acoustic reflexat all.83 cases (20.44%) were Tympanograra Type C and 29(7.14%)TympanogramType As.in cases of the latter two types,the acoustic reflex did not disappear,but the thresholds were raised in a few ears or in certain freqency.
