声音是模拟真实虚拟环境不可或缺的元素。因此，最近有很多研究集中在真实声音效果的模拟上。本文提出了一种为火灾等湍流现象产生声音的方法。在湍流场中，涡流的复杂运动导致声音的产生。这种类型的声音称为涡旋声。所提出的方法通过使用计算流体动力学计算涡度分布来模拟涡旋声。涡流声音的声音纹理首先在预处理步骤中创建。然后使用这些声音纹理以交互速率创建声音。通过将其应用于火声和其他湍流现象的模拟，证明了该方法的实用性。
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.
