The use of lattice gas method in explaining architectural acoustics principles

Abstract

Many concepts in architectural acoustics are based on physical phenomena, such as sound propagation, reflection, etc. In explaining those phenomena, it is necessary to employ the principles of physical acoustics. Unfortunately, the methods of physical acoustics are not easily approachable unless one is familiar with mathematical physics techniques, partial differential equations, for example. The lattice gas method, based on the cellular automata concept, can be an alternative to avoid the use of complicated mathematical equations. A relatively simple code can be used to generate computer simulations. The existing models for sound propagation by Sudo and Sparrow, are examined. Models for other phenomena involving architectural acoustics are suggested.
