Abstract: A structural sound baffle is incorporated into a sheet metal subassembly used in the production of an automotive vehicle, such as a pick-up truck. The structural sound baffle is formed in a Z-shaped configuration that has a first flange welded to the inner panel of the internal cavity, while the second flange is affixed by a heat cured adhesive to the outer panel of the assembly. The baffle joins the two panels to create a more rigid structure than the subassembly without the structural sound baffle affixed thereto. The more rigid structure is less sensitive to boom vibrations, reducing acoustic boom by 64%. In pick-up truck back panel applications, where a retractable window is receivable within the internal cavity of the subassembly, the baffle can be utilized without interfering with the package constraints associated with the retractable back glass configuration.

Abstract: A sound baffle affixed to the sheet metal at the engine compartment of an automobile chassis. The sound baffle is formed of a layer of sound absorbing material affixed to a rigid backing material manufactured from metal, plastic or other rigid material to provide structural support for attachment of the sound baffle to the sheet metal chassis structure. The sound baffle can be affixed to the sheet metal of the engine compartment by non-metallic push pins to provide an assembly that can be easily assembled and will be effective in use.
