ABSTRACT:
A Helmholtz resonator is disposed interiorly of a gas-carrying conduit to attenuate noise passing through the conduit. The Helmholtz resonator encloses a volume that is communicated to the gas flow by a through hole in the wall of the enclosure. The conduit comprises two parts that telescopically snap together to capture the Helmholtz resonator.
