Abstract

This paper investigates computer simulation of sound fields in acoustical environments. All the contemporary acoustical computer models represent the room to be modelled as a series of flat or planar surfaces. Generally these surfaces must have many edge vertices but must be contained in a single plane. That means that curved walls are required to be represented by a finite number of flat planar segments. The quality of the overall simulation process is directly related to the three dimensional geometrical and acoustical model and obviously the restriction of flat surface representation is a negative factor. Further the use of a large number of planar surfaces to represent a curved wall is inefficient, since as the number of surfaces increases the number of cal
