This paper gives thresholds for direct sound and early reflections simulated by a virtual reality system. An auralization system would ideally utilize a large number of accurately modeled early reflections parameters, but there are practical DSP limitations for real-time rendering. A perceptual solution for data reduction involves determining early reflection thresholds as a function of time and spatial incidence.
