Objective evaluation of scattered sound field: Theory and methodology of diffuser design

확산음장의 물리적 평가 - 확산체 설계이론과 방법론 -

The effect of a scattering wall surfaces on sound diffusion can be assessed by determining the scattering and diffusion coefficients in the laboratory. However, the sound field in a concert hall including scattered reflections is different from the laboratory measurement condition. Therefore, there is a need for objective investigation of diffusion in real sound fields. In this paper, possible acoustical parameters of in-situ measurements are discussed.
