Abstract
Noise insulation may be provided by an anti-resonant panel that includes a base panel including a base panel core material and two base panel face sheets, where each of the two base panel face sheets is adjacent to an opposite side of the base panel core material. The anti-resonant panel further includes at least one stiffener-member positioned along the base panel in a defined area of the base panel, where the defined area is less than a full area of the base panel. The stiffener-member includes a stiffener-member core having a top surface, a bottom surface in contact with the base panel, a plurality of cells having walls that extend from the top surface to the bottom surface, and a stiffener-member face sheet that is seamlessly integrated with the walls of the plurality of cells along the top surface.
