摘要
针对汽车排气消声系统管道的结构和参数对排气噪声的影响,分析了其易于在计算机上实现的消声量计算方法,阐述了结构参数的变化对噪声大小和频率特性的改变。
Aiming at the influence of automobile exhaust systems structure and parameters on noise.This paper analyses on calculatimg method of insertion loss which can be simply achieved on computer Also,it expounds the variations of noise level and frequency characteristic along with the changes of structure and parameters All of this provide the basis and the way for designing silencer reasonably
