During the past three decades, there has been a growing concern over the in crease in noise pollution that comes as a direct result of the increased volume of automobile traffic, high-speed trains, and larger aircraft. Additional sources of noise are commonly found in air handling equipment (such as fans and pro pellers) and a variety of machinery used in construction and manufacturing. A vast majority of these noise sources are the result of a given system's aero acoustic response, or sound generated by the interaction of a flow field with the given structure. While barriers are commonly used to shield communities from highway and train noise, and absorption materials are used to shield machinery noise, there is no way to shield communities near major airports from the noise gen erated by low-flying aircraft. Tens of millions of people worldwide are affected by this airport noise problem. In densely populated Europe, up to 15 % of the total population is strongly influenced by airport noise. Since the volume of air traffic will continue to grow, so too will the problem and the number of people involved. It is not surprising that many countries and communities have taken legal action to preserve the quality of life in these areas. As a result, the airlines, airports, manufacturers and governments are working together to set new standards for aircraft noise reduction. In order to establish realistic goals, the generation and propagation of acoustic sources must be better understood. The goal of aeroacoustic measurements is to provide a basis for assessing mechanisms of noise generation, and to develop methods of reducing noise to more acceptable levels. However, the measurements themselves are complex, and require a deep understanding of the experimental facility utilized (such as a wind tunnel), measurement instrumentation, and data analysis techniques.
In this volume recent advances in the measurement and understanding of aerodynamically generated sound are presented by leaders in the development of new techniques in this field. Both basic and applied problems are covered in detail.

From the reviews:

"Aeroacoustic Measurements, edited by Thomas Mueller, aims to provide a single reference volume for practitioners assembled by acknowledged experts in the field. ? Throughout Aeroacoustic Measurements there are up-to-date case studies, real experimental data and references to put the information in context and show its practical relevance. Its unique strength is the considerable amount of low-level technical detail that would otherwise remain unavailable ? . This well-written and concise volume will prove to be invaluable for those involved in aeroacoustic measurement work ? ." (K. Takeda, Journal of Fluid Mechanics, Vol. 502, 2004)
