Room sound field prediction by acoustical radiosity Nosal, Eva-Marie
Abstract
Acoustical radiosity is a technique based on assumptions of diffuse reflection and incoherent phase relationships that has been used to predict room sound fields. In this research, the background to acoustical radiosity is given, the integral equation (on which the technique is based) is derived, and a numerical solution is detailed for convex rooms of arbitrary shape. Several validations are made by comparison of the numerical solution to (1) analytical solutions for a sphere; (2) results from a ray tracing algorithm in cubical enclosures, and; (3) measurements in three real rooms.
