空腔音调是当空气流过空腔的开放表面并且满足许多物理条件时产生的声音。利用从流体动力学和空气动力学研究中获得的方程来产生真实的空腔音调，而无需解决复杂的计算。合成是通过物理模型进行的，其中空腔的几何形状用于声音合成计算。该模型实时运行，非常适合集成到游戏或虚拟现实环境中。通过将我们模型的输出与之前发布的实验、理论和计算结果进行比较来进行评估。结果表明，理论声强和声音传播方程的准确实现以及非常好的频率预测。
The cavity tone is the sound generated when air flows over the open surface of a cavity and a number of physical conditions are met. Equations obtained from fluid dynamics and aerodynamics research are utilised to produce authentic cavity tones without the need to solve complex computations. Synthesis is performed with a physical model where the geometry of the cavity is used in the sound synthesis calculations. The model operates in real-time making it ideal for integration within a game or virtual reality environment. Evaluation is carried out by comparing the output of our model to previously published experimental, theoretical and computational results. Results show an accurate implementation of theoretical acoustic intensity and sound propagation equations as well as very good frequency predictions.
