Abstract: An acoustic suppression arrangement 7 for a component undergoing induced vibration is provided. The arrangement 7 includes a component body 8 having an interior surface 9 and an exterior surface 11 having a panel portion 20. A containment plate 24 is provided having a spaced relationship from the panel portion. A first projector 25 is connected to the component body panel portion 20 and extends toward the containment plate 24. A second projector 30 is connected to the containment plate. A connector system 39, 45 is provided to connect the containment plate 24 to the component body 8 while placing the first and second projectors 25, 30 in an interference fit. Vibratory energy of the component body 8 is dissipated by frictional contact between the projectors 25, 30.
