Abstract: A sound attenuation panel is configured with a substantially acoustically transparent planar, rigid frame divided into a plurality of individual, substantially two-dimensional cells. A sheet of a flexible material is fixed to the rigid frame, and a plurality of platelets fixed to the sheet of flexible material such that each individual cell of the plurality of cells is provided with a respective platelet to establish a resonant frequency, the resonant frequency defined by the planar geometry of the individual cells, the flexibility of the flexible material and the platelets. The cells are divided into at least two different types of the individual cells, configured so that sound waves emitted by a first type of said different types of individual cells establishes a sound cancellation pattern with sound waves emitted by a second type of said different individual cells or an aggregation of different types of the individual cells.
