Abstract
A damped structural panel includes a panel having bending modes including demanding bending modes. The demanding bending modes have subsonic bending waves along at least one axis, and require damping treatment based on sound radiation properties of the panel. A viscoelastic material is applied within a limited area adjacent to the panel edges based on the demanding bending modes. The viscoelastic material damps sound radiation caused by bending waves during use of the structural panel, such as use as a body panel on an aircraft.
