Abstract: Successful acoustic design of auditoria for speech or music requires amodelling technique that is sufficiently detailed to include the relevant parameters, without being overly complex.Results from the model can then be applied to various objective measures of sound quality from which design choics could bemade.These measures could be the distribution of sound energy within the auditorium, reverberation time, subjective spaciousness [Hand clarity index [1].Two kinds of well established models are used: the ray tracing technique [2.3] and small scale physical acoustic models [4].The acoustic models require arduous modelling of the surface materials and can have problemsat high frequencies for large auditoria because of the absorption of sound by the air.There can also be difficulties obtaining the correct directivities for the sound sourcs.However, these high frequency problems with large auditoria are not experienced with small scale models in which light replaces sound.The aim here, therefore, is to introduce a small scale light modelling technique which provides more information than previous light models [5], giving the intensity, time delay and direction of re ections and
