Panel assembly with noise attenuation system
A panel assembly includes a first panel defining a surface, and a boom attenuation panel. The boom attenuation panel includes a circumferential edge, and a central portion. The boom attenuation panel is attached to the surface of the first panel, along the circumferential edge of the boom attenuation panel. The central portion of the boom attenuation panel is spaced from the surface of the first panel a gap distance to form a gas chamber between the surface of the first panel and the central portion of the boom attenuation panel. The gas chamber contains a gas that is moveable within the gas chamber in response to wave-like motion of the first panel. Movement of the gas increases the effective acoustic mass of the boom attenuation panel, and damped the wave-like motion of the first panel, which operates to reduce noise generated from the wave-like motion of the first panel.
