A baffle assembly for a hollow cavity is disclosed. The baffle assembly includes a labyrinth that defines a tortuous drain passageway. The baffle assembly includes a vertical portion that abuts an expandable material to reduce the transmission of noise and other vibrations.
Claims16
A baffle assembly, comprising:
- a substantially planar carrier having an upper surface and a lower surface;
- and
- a drain housing extending upwardly from said upper surface, wherein said drain housing includes a cavity interconnecting a fluid inlet and a fluid outlet, and a generally vertically oriented web portion that extends from an interior surface of the drain housing to define at least a portion of a drain path through said cavity.
A drain housing for dissipating sound therein, comprising:
- a generally vertically oriented planar web portion that extends from an interior surface of said drain housing to define at least a portion of a drain path through said drain housing, wherein said web portion defines two legs of said drain path, wherein said two legs of said drain path flow in opposite directions.
A method of reducing noise propagation through a partially enclosed cavity comprising the steps of:
- positioning a drain housing in a desired location within the partially enclosed cavity, wherein said drain housing includes a fluid inlet;
- positioning an expandable material adjacent said drain housing;
- and
- expanding said expandable material such that said expandable material at least partially encloses said drain housing.
