Frontiers in Aeroacoustics includes recent developments that are both fundamental and applied. Aeroacoustics is a growing specialization that has received fresh emphasis due to advances in air, ground and space transportation. We need significant advances in aeroacoustics to reduce community and cabin noise from subsonic aircraft and to prepare for the possible large-scale entry of supersonic aircraft into civil aviation. We also need new research and effective communication about results to meet higher noise-certification levels and to pre-empt further regulatory burdens.
In recent years, public awareness and perception of transportation noise has changed significantly. There is lower tolerance about noisy situations because of factors such as hearing loss, annoyance, sleep deprivation, and structural fatigue. Government and private parties are exerting pressure to make noise regulations progressively more stringent. Equipment manufacturers are striving to increase performance while lowering noise not only for transportation but for all kinds of consumer products.
The use of advanced measurement techniques has proliferated. This includes phased arrays used with advanced beamforming algorithms, higher order spectral analysis and time frequency localization methods.
All of the advamces mentioned above have created the need to compile state-of-the art knowledge into a single concise volume. The range of topics covered in this book includes advances in experimental aeroacoustics, instabilities and shocks in single and multiple jets, jet noise measurements, noise reduction using chevrons, generalized acoustic analogy, vortex sound, multidimensional generalized functions and Greens functions in aeroacoustics. Other topics include sound in piping systems and aspects of combustion noise.
The perspectives in this book are those of internationally recognized experts in the field. The book will provide a student, scientist or practicing engineer a concise overview of aeroacoustics developments and a good starting point for further research.
