![]() The modeling of structure-borne sound is excluded from this overview because the related noise propagation models are typically quite different from the techniques discussed here. From algorithmic and computational viewpoints, these techniques are similar, although the requirements for performance and accuracy are different. ![]() However, this overview is not limited to only room acoustic design but also covers GA modeling techniques developed for other areas such as virtual reality applications, cognitive research, and training. (68)90198-3 which utilized ray tracing for computing time-energy responses and showed its applicability to practical room acoustic design. ![]() in 1968, 3 3.Ĭalculating the acoustical room response by the use of a ray tracing technique,” J. Time-wise, this means that we concentrate on developments after the publication of the landmark paper by Krokstad et al. ![]() Our focus is on techniques that can be used to simulate sound propagation inside three-dimensional (3D) spaces to produce impulse responses and/or time-energy responses. The goal of this overview is to present the history and state-of-the-art of all the main geometrical room acoustic modeling techniques. ![]()
