ABSTRACT:
A low vibroacoustic structure 10 according to the present invention comprises a first facesheet 12 defining a plurality of first holes 22, a second facesheet 16 defining a plurality of second holes 36, and a core 14. The first and second facesheets are attached to opposed surfaces of the core. The core defines a plurality of passages 32 in communication with the first and second holes to form channels 38 through the structure. The core is typically a honeycomb sheet. The first and second facesheets and the core are formed of lightweight materials such as lightweight metals, metal matrix composites, or polymer matrix composites. The perforated structure reduces structural acoustic coupling and acoustically induced vibration. The structure can be formed as a panel. The panel can be attached to support structures exposed to high-energy acoustic environments to reduce acoustically induced vibration of the structures.
