A composite foam cushion for a sound control device. The cushion includes a core formed of a polymeric foam material and a polymeric coating overlying at least a portion of the core of polymeric foam material. The polymeric coating includes an outer coating layer and an inner polymeric coating layer bonded to the core of polymeric foam material. The inner coating layer may provide the cushion with strength, while providing a high degree of flexibility and suppleness to closely conform around contours and obstructions. The outer coating layer may provide the cushion with enhanced abrasion resistance and/or chemical resistance while having an aesthetically pleasing feel and appearance.
