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...
[ What is claimed is:] [1.] A low vibroacoustic structure, comprising:(a) a core including a first surface, a second surface opposite the first surface, and a honeycomb structure disposed between the first and second surfaces, said honeycomb structure forming a series of passages through the core and extending through the first and second surfaces;(b) a first facesheet having a predetermined facial area on the first surface of the core, the first facesheet defining a plurality of first holes therethrough; and(c) a second facesheet having a predetermined ...
