AB  - Diffusion and scattering are becoming increasingly relevant in room acoustics design. The scattering performance of current passive diffusers is often restricted to a certain bandwidth due to physical constraints. One possible approach to this is to use fractal surface profiles, which have similar geometric features over a wide range of scales, and so should achieve an extended bandwidth for effective scattering. A range of acoustic panels of varying complexity, based around Koch’s Snowflake pattern, was constructed and tested using a two-dimensional pseudo-anechoic method adapted from the AES-4id-2001. This paper reports on these results, and also on issues encountered in implementing the measurements.
