A new algorithm for the simulation of sound propagation in spatial enclosures

Traditional algorithms for the simulation of sound propagation in spatial enclosures include the image source method and the ray-tracing method. These algorithms are computation intensive and take a long time to generate results. In this paper, a new algorithm is proposed for the simulation of sound propagation in spatial enclosures that is relatively fast. This algorithm is based on modeling the surfaces of a spatial enclosure as sound radiators. The purpose of the algorithm is to generate an energy response graph at a certain listening location based on a sound source. Acoustical parameters such as Clarity (C50, C80) can be calculated from this graph. These parameters can then be used to assess the acoustical quality of the space.
