ABSTRACT:
A muffler for impeding and reflecting exhaust to reduce the formation of sound waves through a plurality of cone and barrier assemblies alternately and longitudinally spaced in a cylindrical body, with the apex of a conical member of each cone assembly and an outwardly extending cylindrical portion of each barrier assembly being directed towards the input end of the body. Exhaust flow paths for dissipating exhaust noise are defined by orifices formed in the conical members and cylindrical portions, and spaces between spokes joining each conical member to a circular member.
