在上世纪70年代耳声阻抗测试开始广泛运用于临床,成为诊断中耳病变非常有价值的工具[1]。1970年Jerger[2]首次关于临床运用双频或多频探测音的报道,使声导抗测试有了显著的发展。鼓室导纳测试是检测外耳及中耳功能的一种客观手段,与大多数听力计测试不一样,它不是对听力的测定, In the 1970s, otoacoustic impedance tests began to be widely used in clinical practice, becoming a valuable tool for the diagnosis of middle ear disease [1]. In 1970, Jerger [2] first reported the clinical application of dual-frequency or multi-frequency detection sound, the acoustic conductivity test has made significant progress. Drum admittance test is to detect the outer ear and middle ear function of an objective means, unlike most audiometer test is not the same, it is not a measure of hearing,
