Unsteady flows around a door mirror mounted on a passenger car were computed using a third-order upwind-difference scheme and an overset grid technique. Aerodynamic noises in far field, emitted from the mirror, were calculated from pressure fluctuation on the surface using Curle's equation. They were synthesized by an Apple Macintosh.<BR>Flow were separately visualized on a graphic workstation. Rendered images were transferred to the Macintosh. Those images and the synthesized sounds were edited into a video tape. We could evaluate the aerodynamic noise by our own ears without any physical model and investigate the relationship between flows and sounds in detail.
