摘　　要：介绍了声强法测定车辆气源装置噪声的优点与其原理,应用p-p声强技术对某型气源装置进行了测试,通过对其近场表面声功率及其频谱的分析,识别出主要噪声源、主要频率构成以及整个装置的噪声辐射强度,为车辆气源装置噪声防治提供了理论依据。The principle and advantages of the sound intensity method for noise determination of vehicle gas source device were introduced. In order to study the overall noise of gas source device, the noise of gas source device was tested using p-p sound intensity technique. The sound power and 1/3 octave spectrum on each segment of gas source device were analyzed. Then the position of main noise source ,main noise frequency and overall radiation intensity were identified. The results can provide theoretical basis for the prevention of noise pollution of vehicle gas source device.
