摘要
用二维声学边界无法建立汽车排气消声器降噪计算模型，计算排气消声器的插入损失，经与汽车匀速行驶车外噪声试验比较，表明二维声学边界元模型是消声器设计的一种简捷有效的计算方法。
In this paper,the reduced noice model of the automobile exhaust muffer based on boundary element method is built, the insertion lose eyalutod ability of noice elimination by this model is calculated and is compared with the results of automobile driving tests. It is demostrated that the boundary element method model in twodimension is useful in designing calculation of the exhaust muffer.
