This paper presents the results of objective and subjective evaluation of a simulation/auralisation system based on model CRR – combined ray-tracing and radiosity. Auralisation of an urban square has been carried out with various boundary reflection patterns (purely specular, purely diffuse and mix of specular and diffuse), using two audio stimuli. The subjective evaluation results reveal a strong impact of sound sources and reflection pattern. Despite similarities in objective measures, there are noticeable differences in subjective attributes between signals based on simulated and measured impulse responses, but current auralisation algorithms are still adequate in simulating real urban environments.
