T3 - ABSORBERS AND DIFFUSERS
Trevor Cox, University of Salford - Salford, Greater Manchester, UK
Absorbers and diffusers are two of the main design tools for altering the acoustic conditions of rooms such as studios and auditoria, semi-enclosed spaces such as stadia and the outdoor environment. Absorbers also have a crucial role within loudspeaker enclosures and in the reduction of machinery noise. This tutorial will describe state-of-the-art designs for diffusers and absorbers, as well as touching on techniques for measuring and modeling these treatments. Surface diffusion is a relatively young subject area, and case studies will be drawn upon to show when are where diffusers can be used to improve conditions. Absorption is a more established technology, and yet new materials and techniques continue to be developed today, for instance driven by the need for more sustainable buildings.
