摘　　要：文章简要介绍了水管路消声器声阻抗的测试方法,对两端不对称的管路元件—水消声器的四个声阻抗参数进行了测试研究。试验结果显示符合声阻抗变化规律,验证了传递声阻抗的互易性。表明管路元件声阻抗测试方法与试验装置可应用于消声器的声阻抗测试。The measurement method on acoustic impedance of silencer in water pipe is introduced. Four acoustic impedance parameters of double end asymmetry silencer in water pipe were tested. The measurement results are in conformity with the characterization of the acoustic impedance. And the reciprocity of transfer acoustic impedance is verified. This acoustic impedance test methods and equipments can be applied to measuring silencers.
