Abstract
A shape for sheet metal stampings is provided that will minimize the radiation of sound from the panel, to thereby reduce or eliminate the need to add supplemental acoustical absorbing or barrier materials. The sheet metal panel shape includes a crown portion, a peripheral flange that extends around the boundary of the crown portion, a flat portion that truncates the crown, and a bead pattern that is formed in at least the flat portion of the panel, whereby the crown and the flat and the bead pattern cooperate to define a panel shape that has low sound radiation. The bead pattern can also extend part way or more into the crown portion.
