The goal of this research project was to determine whether a simple 3D model for multi-loudspeaker simulation of room reverberation could produce identifiable differences in room geometry. This simple, image-model-based simulation was designed to produce distinctive-sounding results as the material was varied on each of the six walls of a modeled rectangular room. A realistic- sounding wall-reflection simulation was developed and submitted to blind listening experiments designed to test whether listeners could determine which one of five walls had been eliminated from the simulation. Though listeners were not particularly good at this identification task, they were able to consistently distinguish between the spatial images associated with these five cases (five room geometries).
