摘　　要：阐述了轿车车内噪声分析及控制的方法。以某国产新型轿车后排座噪声较大的问题为例,从结构传播噪声和空气传播噪声两方面,对试验样车进行了各项道路试验,识别出影响车内噪声的主要噪声源。在此基础上,针对不同噪声源采取了各项减振降噪措施,取得了满意的降噪效果,为该车车内噪声控制途径指明了方向。A method of car interior noise analysis and control was presented to resolve the loud rear seat noise problem in a new indigenous car. Following the two noise propagation routes, the structure-borne noise and the airborne noise, road tests were done and the major sources of rear seat noise were identified. Base on these results, modifications were taken for different noise sources and the noise level was reduced to a satisfied level, providing a basis to control interior noise for the car.
