摘要
阐述车内噪声发生机理及传播途径,从减弱声源强度、控制噪声传播途径、吸声处理和主动噪声控制四方面论述降低汽车车内噪声的方法与手段。
This paper described the mechanism of inner noise generation and its transmission route of automobile. The methods to lower automobile inner noise were discussed in four aspects： to decrease noise source intensity, to isolate transmission route, to raise sound absorption, and to control the active noise.
