摘要：A muffler (10) for reducing the noise level of gases passing therethrough isdisclosed. The muffler (10) includes a housing (12) including a longitudinally extendingwall (14) and a pair of opposite end walls (16, 18). Baffle plates (32, 38, 42) divide theinterior space of the housing (12) into a Helmholtz resonator chamber (34), a flowchamber (36), an inlet broad band attenuator chamber (40) and an outlet broad bandattenuator chamber (44). An inlet tube (20) extends through an inlet port (21) in the endwall (16), through a hole (48) in the baffle plate (38) and through a hole (50) in the baffleplate (32). An outlet tube (22) passes through an outlet port (23) in the end wall (18),through a hole (52) in the baffle plate (42) and through a hole (54) in the baffle plate (32).Exhaust gases enter the muffler (10 ) through the inlet tube (20), pass through holes (62)into the flow chamber (36) and exit the muffler (10) through the outlet tube (22). Broadband attenuation of noise being carried by the exhaust gases occurs in the inlet andoutlet attenuation chambers (40, 44) and in a nozzle member (80). Narrow band noiseattenuation occurs in the Helmholtz resonator chamber (34).
