风音是空气流过圆柱体或类似物体时发出的类似口哨的声音；它是主要的气动声源之一。基于从基本流体动力学方程导出的经验公式，开发了风音的合成模型。它避免了耗时的计算并允许实时操作和交互。综合模型的评估表明，产生的频率接近于风洞中测量的频率或通过传统离线计算模拟的频率。
An Aeolian tone is the whistle-like sound that is generated when air moves past a cylinder or similar object; it is one of the primary aeroacoustic sound sources. A synthesis model of an Aeolian tone has been developed based on empirical formula derived from fundamental fluid dynamics equations. It avoids time consuming computations and allows real-time operation and interaction. Evaluation of the synthesis model shows frequencies produced are close to those measured in a wind tunnel or simulated through traditional offline computations.
