Claim:
1. A panel assembly comprising: a first panel defining a surface; a boom attenuation panel having a circumferential edge and a central portion; wherein the boom attenuation panel is attached to the surface of the first panel along the circumferential edge of the boom attenuation panel; wherein the central portion of the boom attenuation panel is disposed in a generally parallel relationship with the surface of the first panel, and is spaced from the surface of the first panel by a gap distance to form a gas chamber between the surface of the first panel and the central portion of the boom attenuation panel in order to reduce noise generated from a wave-like motion of the first panel; and wherein the gas chamber contains a gas that is moveable within the gas chamber in response to wave-like motion of the first panel; wherein the boom attenuation panel is continuously attached to the first panel, around the entire circumferential edge of the boom attenuation panel, to completely seal the gas chamber and prevent the escape of the gas from the gas chamber between the circumferential edge of the boom attenuation panel and the surface of the first panel; wherein the boom attenuation panel includes and is manufactured from a fiber reinforced cardboard material.
