This paper presents experimental studies on methods for reducing air flow noise which is generated in expansion cavity type mufflers. A great deal of air flow noise is generated when a jet stream from the inlet pipe directly impacts the tail pipe, so it is necessary for the flow noise reduction to reduce the impact energy. In this paper, the effects of various methods for the reduction of impact energy and air flow noise are systematically studied.
