Abstract
Sound is an indispensable element for the simulation of a realistic virtual environment. Therefore, there has
been much recent research focused on the simulation of realistic sound effects. This paper proposes a method for
creating sound for turbulent phenomena such as fire. In a turbulent field, the complex motion of vortices leads to
the generation of sound. This type of sound is called a vortex sound. The proposed method simulates a vortex sound
by computing vorticity distributions using computational fluid dynamics. Sound textures for the vortex sound are
first created in a pre-process step. The sound is then created at interactive rates by using these sound textures. The
usefulness of the proposed method is demonstrated by applying it to the simulation of the sound of fire and other
turbulent phenomena.
