Duct Acoustics
Cambridge University Press (Verlag)
978-1-108-84075-0 (ISBN)
foundations of duct acoustics to the acoustic design of duct systems, through practical modeling, optimization and measurement techniques. Discover in-depth analyses of one- and three-dimensional models of sound generation, propagation and radiation, as techniques for assembling acoustic models of duct systems from simpler components are described. Identify the weaknesses of mathematical models in use and improve them by measurement when needed. Cope with challenges in acoustic design, and improve understanding of the underlying physics, by using the tools described. An essential reference for engineers and researchers who work on the acoustics of fluid machinery ductworks.
Erkan Dokumacı is Professor Emeritus of Mechanical Engineering at Dokuz Eylül University (İzmir, Turkey). He is currently on the Editorial Advisory Board for the Journal of Sound and Vibration and is the author of software used for acoustic design of mufflers and silencers, as well as many scientific papers on duct acoustics.
