摘　　要：车辆噪声控制对于防治环境污染和提升车辆乘坐舒适性有着重要意义。文章论述了各国车辆噪声的控制标准及科学准确测量车辆噪声的方法,进而从活塞式内燃机汽车的结构出发,着重梳理归纳了该型车辆行驶过程中的噪声源,有针对性地分析了发动机噪声、底盘噪声、电器设备噪声和车身噪声这4类噪声的特点,并对这4类噪声的控制技术进行了研究。Noise control is of great importance for the prevention and control of environmental pollution and the improvement vehicle ride comfort. This paper describes the noise control standards of vehicle and scientific and accurate measuring method in many countries. In turn, starting from the structure of piston type internal combustion vehicle, this paper sums up vehicle noise source in the process of driving, then classifies the noise according to the noise source, and analyzes the character of engine noise, chassis noise, electrical equipment noise and vehicle noise.Then, the four types of noise control methods were given.
