On the modification of phonon tracing
Phonon tracing is a geometric approach estimating acoustics in closed rooms. This work contains discussions of possible refinements and extensions of the algorithm. In computer graphics exist numerous level-of-detail approaches decreasing the representation details of objects in order to speed up computations and rendering of virtual scenes. Different ideas for the realization of a level-of-detail approach in acoustics are presented. For this purpose the phonon tracing algorithm has to be modified. With these modifications the room impulse response can be calculated with respect to the user requirements on calculation time and accuracy.
