Simulation of acoustic environments—Part 2: Can we trust the computer?

Abstract

The lessons learned from the “round robins” are that the main bottlenecks in room acoustic computer simulations are lack of data of 3D characterization of sound sources and material parameters, and interfaces to spatial audio technology. This presentation focuses on sources of uncertainties in such computer models and on the challenges in solving indoor acoustic problems. Also, a new initiative towards a fourth “round robin” on auralization is presented, which will be further elaborated in other papers of the special session.
