초록

A muffler of the Helmholtz resonator type has a housing surrounding a main gas flow conduit, the gas flow conduit having an apertured zone within the housing wherein apertures extend through the conduit wall, the shape of the conduit wall at the apertured zone being so varied that gas flows through the apertures into or out of the housing, the flow inhibiting the development of whistle noises.
