Fully updated second edition of the premier reference book onmuffler and lined duct acoustical performance
Engine exhaust noise pollutes the street environment andventilation fan noise enters dwellings along with fresh air. Peoplehave become conscious of their working environment. Governments ofmost countries have responded to popular demand with mandatoryrestrictions on sound emitted by automotive engines, and a thoroughknowledge of acoustics of ducts and mufflers is needed for thedesign of efficient muffler configurations. This fully updatedSecond Edition of Acoustics of Ducts and Mufflers deals withpropagation, reflection and dissipation/absorption of sound alongducts/pipes/tubes, area discontinuities, perforated elements andabsorptive linings that constitute the present-day mufflers andsilencers designed to control noise of exhaust and intake systemsof automotive engines, diesel-generator sets, compressors and HVACsystems.
It includes equations, figures, tables, references, and solvedexamples and unsolved exercises with answers, so it can be used asa text book as well as a reference book. It also offers acomplete presentation and analysis of the major topics in soundsuppression and noise control for the analysis and design ofacoustical mufflers, air conditioning and ventilation duct work.Both the fundamentals and the latest technology are discussed, withan emphasis on applications. Deals with reactive mufflers,dissipative silencers, the frequency-domain approach, and thetime-domain approach.
* Fully updated second edition of the premier reference book onmuffler and lined duct acoustical performance, in one completevolume
* Presents original new research on topics including bafflesilencers and louvers, 3D analytical techniques, and flow-acousticanalysis of multiply-connected perforated-element mufflers
* Includes a general design procedure to help muffler designersin the automotive industry, exhaust noise being a major componentof automobile and traffic noise pollution
* Written by an expert with four decades' experience inteaching to graduate students, publishing extensively in reputedinternational journals, and consulting with industry for noisecontrol as well as designing for quietness
