Patent attributes
An exemplary inventive acoustic wall panel includes a pair of congruent flat rectangular plates and a housing. The two plates adjoin at their respective vertical edges to form an angle Ø between the two plates, wherein 90°≤Ø<180°. Each plate has a material characteristic relating to acoustic reduction through the plate. Design of an inventive wall panel includes selection of the angle Ø and the respective plate materials, with an objective of producing counteractive acoustic vibratory motions in the two plates in response to sound waves impinging upon the inventive wall panel. Acoustic vibratory motion is induced in each plate whereby the respective vibratory motions tend to oppose each other, thereby reducing sound transmission across the inventive wall panel. The housing lends support to the two attached plates and facilitates connection of the inventive wall panel to another inventive wall panel or to a different structure.
