Abstract
The auditory rendering in a VR system either entail real, acoustical measurements of the room, or – more commonly – a model of the room rendered. The models are usually based on relatively coarse approximations of the geometry, and the calculated room impulse responses deviate from measured impulse responses by having more “distinct” representations of the individual reflections. When rendered audible, such descriptions will lead to a sound quality that can best be described as “canned”. For the rendering of real rooms, as e.g. in "teletransporting", this problem may be addressed by using high resolution scans of the room surfaces as basis for the room models. In the present work this approach is evaluated with a voxel-based method (described in earlier publications), and compared to measured impulse responses. The results are compared objectively by visual inspection of the impulse responses, and by comparison of statistical parameters calculated from measured and modelled data. The work is ongoing.
