Abstract
A vehicle noise reducing assembly includes a trunk structure having a floor panel, an interior wall panel and an exterior wall panel. A trunk storage area is defined by the interior wall panel and the floor panel. A trim panel is connected to the interior wall panel within the trunk storage area. A cavity is defined by the floor panel, the exterior wall panel and the trim panel and has a first cavity and a second cavity. A relief valve is disposed in a vent opening in the exterior wall panel. The relief valve extends into the first cavity and has a drafter opening facing inboard. A barrier member is disposed in the second cavity with a barrier surface positioned between the relief valve and the second cavity to prevent sound passing through the drafter opening from entering the second cavity.
