Survey of Methods for Modeling Sound Propagation in Interactive Virtual Environment Systems
Résumé
This paper surveys concepts, algorithms, and systems for modeling sound propagation ininteractive virtual environment applications. First, we review physically-based geometric algorithmsfor modeling the propagation of early arriving sound waves. Second, we describeperceptually-based statistical techniques that provide late reverberation effects. Finally, wecompare auditory display systems that produce spatialized sounds using headphones or speakers.
