Simplified closed form equations are developed to predict the sound power radiated from a simply supported rectangular flat plate in an infinite rigid baffle. A modification is added to include the effect of periodic uniform ribs in either uni-directional or a cross hatch pattern. The equations are correlated to finite element/acoustic code analysis. The accuracy of the equations is presented for typical induction system components and an expression is developed to predict the error for other panel configurations.
