文章提出了电流激励下电容器噪声辐射比的测试方法，在理论分析电容器噪声辐射特性的基础上，建立了半消声室内测量电容器噪声辐射比的测试系统，在电流激励下采用振声频响函数法得到电容器的噪声辐射指数曲线。最后，依据电容器噪声辐射指数曲线计算得到电容器表面噪声声压值，并与实测噪声声压值进行对比，验证了方法的准确性。

The test method of noise radiation ratio of capacitor under current excitation is put forward . T hen the noise ratio measuring system in semi‐anechoic room is established based on the theoretical a‐nalysis of the characteristics of capacitor noise radiation .The capacitor noise radiation index curve un‐der current excitation is gotten by the method of vibration acoustic frequency response function .Final‐ly ,on the basis of capacitor noise radiation index curve ,the sound pressure value of capacitor surface is calculated and compared with the measured value to verify the accuracy of the method .
