BASIC AERODYNAMIC NOISE THEORY
The present state of knowledge in the theory of aerodynamic noise generation and propagation is outlined, with emphasis on the identification and the physical and analytical modeling of the major sound sources associated with turbulent airflows. The importance of source coherency with regard to flow inhomogeneities is outlined, and the relevance of studies into the sound propagation from acoustic singularities embedded in a sheared flow is discussed with respect to the jet noise problem.
