abstract = {Acoustic obstruction is a difficult challenge faced in virtual reality and games. Obstruction is the loss in audio loudness due to objects and doorways that intervene the line-of-sight between a sound source and listener. Visual obstruction using a single ray-cast is fast to compute, but too abrupt for audio, sounding obviously unrealistic. On the other hand, using a full wave simulation is accurate but computationally expensive, requiring pre-computation. In this paper, we try to balance the two extremes with a new heuristic approach (PCD) that is orders-of-magnitude faster than wave simulation and shows promise for evolving into a real-time technique. We show that PCD captures the qualitative behaviors expected from wave diffraction.},
