| Abstract: | The last 20 years have seen great developments in the sound-field prediction, measurement of diffusing surface, and product research and development, which deepen our knowledge concerning diffusion and its effects on sound-field and sound quality. Now we have the ability to evaluate, design and optimize diffuser, which has expanded the acoustical palette significantly. |
