电声阻抗测听法(Electroacoustic Impedance Audiometry),是国外近20余年来逐步开展的一种新的客观耳功能检查法。目前、国外对此检查法的一些问题尚在继续研究;国内由于仪器设备等关系开展此项检查单位甚少。为了根据我省高原地区及不同民族等特点,确定不同条件下正常人耳声阻抗值,以利 Electroacoustic impedance Audiometry (Electroacoustic Impedance Audiometry), is a new objective objective function test method developed gradually abroad for more than 20 years. At present, some problems of this inspection method abroad are still continuing to be researched. There are very few units in China due to the relationship between instruments and equipment. In order to determine the normal human otoacoustic impedance under different conditions according to the characteristics of the plateau region and different ethnic groups in our province,
