Diffusion keeps sound waves from grouping, so there are no hot spots or nulls in a room. In fact, diffusion greatly widens the "sweet spot" and lends a strong, 3D sense of openness to a room, making it easier to hear "into" a mix. In conjunction with absorption, diffusion can effectively turn virtually any space into one that is appropriate and useful for the purpose of recording or monitoring sound with a high degree of accuracy.
Diffusion is accomplished by alleviating large, flat, reflective room surfaces and instead, introducing surfaces of scientifically designed varying shapes, sizes and angles. Auralex offers several proprietary diffusors to serve any sonic, architectural or budgetary need.
