Abstract

An reverse type silencer (10) is combined with a resonance type silencer (20). The resonance type section has a core (22) housed in a shell (26) and filled with a sound absorbing material. Open notches (24) are spirally arranged in the core (22) and include downwardly depending lips (28) forming openings to incoming wave forms. Second waves passing the silencer are reflected and attenuated to dampen noise.
