Abstract

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.

Description

technical field [0001] The present invention relates generally to a panel assembly, and more particularly to a body panel assembly for use with a vehicle body for attenuating cabin noise. Background technique [0002] Slight movement of the panel can also create and / or perpetuate noise. Where the panels form a cabin area, such as the outer body panels of a vehicle, any noise caused or transmitted by movement of the panels may propagate to the cabin area, adversely affecting the driving experience of passengers within the cabin area. Therefore, there is a need to attenuate the noise generated or transmitted by the body panels to improve the passenger's driving experience. Contents of the invention [0003] A panel component is provided. The panel assembly includes a first panel defining a surface and a cantilever attenuating panel. Cantilevered attenuation panels consist of a perimeter and a central section. The cantilever attenuating panel is attached to the surface of...
