초록

A muffler construction comprising an outer body, and a pair of end walls extend transversely across the body to define an internal chamber. An inlet conduit is located in one of the end walls, while an outlet conduit is in the other end wall. In one embodiment, the inlet conduit is disposed axially of the body to excite symmetric higher order modes and the outlet is offset radially from the axis of the body and is located on a nodal circle of the transverse pressure distribution. In a second embodiment, the inlet is offset from the axis of the body causi...
