ABSTRACT:
A plurality of parallel and laterally spaced impermeable walls define an array of side-by-side elongate fluid filled cavities. Adjacent open ends of the cavities provide a sound-receiving or admittance end for the sound waves into the cavities. An acoustically reflective, preferably impermeable, barrier is disposed adjacent the ends of the cavities remote from their sound-receiving end and terminates the cavities. The cavities are uniquely configured to provide an effective geometrical sound-absorbing structure while minimizing the structural elements required and, thus, the cost of manufacture.
