Visualization of internal sound field by computer simulation based on geometrical acoustic theory

Abstract

We have developed a personal computer simulasion system for the acoustic design. In this system, internal sound field is simulated by sound ray tracing method and image method based on geometrical acoustic theory, and visualized with computer graphics. To visualize internal sound field obtained by simulation is very useful way to exactly grasp characteristics of internal sound field and to easily reflect the simulated results to the acoustic design.
