| Abstract: | A highly effecient method for analyzing the two-dimensional sound fie-ld in muffler is proposed in this paper.Sound pressure is taken as an un-known variable and the two-dimensional coordinate is used. The modelingof exhaust muffler and its application to practical design of type 492Qgasoline engine is described.Computed insertion loss is compared with me-asure results.It shows good agreement. |
