Virtual Environment for Subjective Evaluation of Synthesized Sound 2001-01-1591
Modern PCs are built on multimedia processors designed to handle computer-generated three-dimensional image as well as stereo sound in real time. In this paper we report on research that takes advantage of these recent capabilities. A prototyping system designed to provide an enhanced visual and auditory experience of the interior noise performance of a vehicle was developed. The system can be used for the subjective evaluation of modifications to the sound package of an existing vehicle. The latest virtual reality technology is combined with digital sound processing and Statistical Energy Analysis simulation to provide the user with a unique visual and auditory experience.
