Abstract: A fast and perceptively plausible method for rendering acoustic scenarios with moving sources and moving listeners is presented. The method is principally suited for application in dynamic and interactive evaluation environments (e.g., for hearing aid development), psycho-physics with adaptively changing the spatial configuration, or simulation and computer games. The simulation distinguishes between the direct sound, sound reflected and diffracted by objects of limited size, diffuse sound surrounding the listener, e.g., diffuse background sounds and diffuse reverberation, and ’radiating holes’ for simulation of coupled adjacent rooms. Instead of providing its own simulation of room reverberation, the proposed simulation method generates appropriate output signals for external room reverberation simulators (e.g., see contribution by Wendt et al.). The output of such room reverberation simulators is then taken either as diffuse surrounding sound if the listener position is within the simulated room, or as input into a ’radiating hole’, if the listener is in an adjacent room. Subjective evaluations are performed by comparing measured and synthesized transitions between coupled rooms.
