Two Decades of Sound Diffusor Design and Development, Part 2: Prediction, Measurement, and Characterization

The last 20 years have seen great developments in the prediction, measurement, and characterization of diffusing surfaces. Methods available for predicting and measuring the scattered polar distribution using boundary-element methods and maximum-length sequence stimuli are reviewed. The methods are used currently to characterize the quality and amount of diffusion produced by a surface are described, including diffusivity diffusion coefficients derived from predicted and measured polar distributions and scattering coefficients derived from direct measurements.
