1. Blake, W. K.: Mechanics of Flow-Induced Sound and Vibration, Vol. I: General Concepts and Elementary Sources. ACADEMIC Press INC., Harcourt Brace Jovanovich, Publishers, pp. 1–425,1986. Blake gives a fairly complete survey of the mechanisms of flow-induced sound and vibration. The two volumes include a development of the important equations of aeroacoustics and a special chapter for the noise mechanisms which are relevant for lifting surfaces in general, namely trailing-edge noise and inflow-turbulence noise.

3. Brooks, F. T.; Pope, D. S.; Marcolini, M. A.: Airfoil Self-Noise and Prediction. NASA RP-1218, pp. 1–145, July 1989. Brooks etal. report on boundary-layer and acoustic measurements of 2D NACA 0012 airfoil sections and a 3D tip performed in an anechoic wind tunnel at Reynolds number between 400.000-1 106 and angle of attacks between 0–25°. In the analysis they separated trailing-edge noise, stalled flow noise, laminar-boundary-layer- vortex-shedding noise, tip noise, and blunt-trailing-edge noise. A set of spectral scaling formulas was deduced and implemented in a FORTRAN 77 code, which was given in their annex.
4. Gipe, P. B.: Wind Energy Comes of Age. John Wiley & Sons, New York, Chichester, Toronto, etc., 1995. Gipe chronicles wind energy’s progress from its rebirth during the oil crises of the 1970s through a troubling adolescence in California’s mountain passes in the 1980s to its maturation on the plains of northern Europe in the 1990s. He cites improvements in the performance, reliability, and cost effectiveness of modern wind turbines to support his contention that wind energy has come of age as a commercial technology for generating electricity.
5. Hayden, R. E.: Fundamental Aspects of Noise Reduction from Powered-Lift Devices. SAE Paper 730376, SAE Transactions, pp. 1287–1306,1973. Hay den treats the fundamental aspects of noise reduction from powered lift devices. He gives an overview to the important noise mechanisms (trailing-edge noise, inflow-turbulence noise) and their prediction, and discusses some techniques for noise reduction, for example, the concept of variable impedance.
