Abstract

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.
