This paper presents a design method to optimize the natural frequencies and to minimize the radiated sound power from vibrating plate-like structures. The design method involves creating dimples on the surface of the structure. The dimple can be defined as a local modification in the surface of a structure which has a spherical shape. Creating dimples does not change structural mass but affects its stiffness. Also, addition of dimples alters the plate mode shapes and as a result changes the radiated sound power from the plate. This method is cost-effective in comparison with other structural dynamics modification methods because it can be achieved through a one-step manufacturing method and because it enhances the dynamic behavior of platelike structures without additional weight or added joints.
