Aerodynamic Noise

The growth of aviation and the increasing size and power of aircraft has made aerodynamic noise a major problem for society. In some places the noise has increased beyond the limits of human tolerance. The problem is not new, but because of its complexity not much has been done about it. Some would argue that the increase in noise is an inevitable by-product of the growth of aviation.

Control of this noise will only be possible when more is known of its generation, propagation, and attenuation. To aid in the understanding of the complex problem, the United States Air Force Office of Scientific Research and the Institute for Aerospace Studies, University of Toronto jointly sponsored a symposium on aerodynamic noise in Toronto, May 20-21, 1968, aimed at people involved in research. Papers were invited on the theoretical and practical aspects of noise associated with air flow. Twenty-two of the papers presented are collected here for the use of researchers and engineers concern with aeroacoustics.

Chairman of the symposium was Dr. H.S. Ribner, Professor at the University of Toronto Institute of Aerospace Studies, who edited the volume
