Improvements to Binary Amplitude Diffusers

Document Thumbnail

Improved forms of diffusion structures based on absorption reflection gratings are presented. The theory, design, advantages and limitations of these structures are discussed and their performance presented. Two methods of improving performance are suggested. The first structure is based on diffusion limited aggregation, which models non-regular fractal growth. The second structure was a panel with square absorption patches of a variable size that was determined by an m-sequence. Of the two, the second structure performed best. These are improved diffusing structures that take up less space than phase reflecting ones. These techniques add additional materials to the acoustic designer's armoury, for tackling real acoustic designs that have physical and practical, as well as theoretical, constraints.
