Auralization has become a powerful tool in architectural acoustics practice, research, modern computer games, and other virtual environments to enhance immersion in virtual worlds. In addition, improved understanding of psychoacoustics has enabled focusing of computational resources to the perceptually most relevant parts of the room-acoustic responses. Recent introduction of massively parallel computation via graphics-processing units has significantly speeded up computation to accomplish real-time simulation and auralization. Despite all this progress, there are still plenty of open research questions; therefore, the room-acoustic simulation still remains an active field of research.
