초록

In the present invention an improved sound absorbing panel is provided. The panel comprises an array of wall defining means configured to provide two or more contiguous hollow cells having adjacent open ends and adjacent closed impermeable ends, the open ends defining a sound receiving end of the array, at least one impermeable three dimensional closed surface disposed in at least one of the cells, and a flow resistive permeable facing sheet covering the sound receiving end. Approximately 50 percent of the cells may be filled in a periodic arrangement. T...
