| Abstract: | In this paper, sound pressure being taken as an unknown variable, a three-dimensional acoustic boundary element model of reactive mufflers is established and its application to exhaust muffler design on 492Q type gasoline engines is also described. The computed inserting loss has a good consistency with the experimental result. The research shows that the three-dimensional acoustic boundary clement model is an efficient and highly accurate method of sound field analysis of reactive mufflers. |
