Fully updated second edition of the premier reference book on
muffler and lined duct acoustical performance

Engine exhaust noise pollutes the street environment and
ventilation fan noise enters dwellings along with fresh air. People
have become conscious of their working environment. Governments of
most countries have responded to popular demand with mandatory
restrictions on sound emitted by automotive engines, and a thorough
knowledge of acoustics of ducts and mufflers is needed for the
design of efficient muffler configurations. This fully updated
Second Edition of Acoustics of Ducts and Mufflers deals with
propagation, reflection and dissipation/absorption of sound along
ducts/pipes/tubes, area discontinuities, perforated elements and
absorptive linings that constitute the present-day mufflers and
silencers designed to control noise of exhaust and intake systems
of automotive engines, diesel-generator sets, compressors and HVAC
systems.

It includes equations, figures, tables, references, and solved
examples and unsolved exercises with answers, so it can be used as
a text book as well as a reference book. It also offers a
complete presentation and analysis of the major topics in sound
suppression and noise control for the analysis and design of
acoustical mufflers, air conditioning and ventilation duct work.
Both the fundamentals and the latest technology are discussed, with
an emphasis on applications. Deals with reactive mufflers,
dissipative silencers, the frequency-domain approach, and the
time-domain approach.

* Fully updated second edition of the premier reference book on
muffler and lined duct acoustical performance, in one complete
volume

* Presents original new research on topics including baffle
silencers and louvers, 3D analytical techniques, and flow-acoustic
analysis of multiply-connected perforated-element mufflers

* Includes a general design procedure to help muffler designers
in the automotive industry, exhaust noise being a major component
of automobile and traffic noise pollution

* Written by an expert with four decades' experience in
teaching to graduate students, publishing extensively in reputed
international journals, and consulting with industry for noise
control as well as designing for quietness
