In addition to measuring electronic hardware used for recording, it is also important to be able to measure the performance of the listening room and the acoustical surface treatments used in their design. Typically, the room's geometry and shell design is used to determine the overall modal response. Surface treatment is then used to tailor the reflection pattern to suit the room's use. In practice surface treatments are either absorptive or diffusive or some combination thereof. Absorptive materials have received considerable treatment since Sabine's seminal research, however, diffusive surfaces have only recently begun to get the attention they deserve. This paper describes the goals of a three year research grant funded by the Engineering and Physical Sciences Research Council of the UK (EPSRC GR/L13124) and RPG Diffusor Systems, Inc. to determine a room acoustic diffusion coefficient.
