First Sentence: In the broadest sense, a sound wave is any disturbance that is propagated in an elastic medium, which may be a gas, a liquid, or a solid.
From Book News, Inc. -- Provides design engineers with specific technical information needed for solutions to the most frequently encountered noise and vibration problems, conveying physical insights into the processes of noise generation and attenuation so that a chosen solution is not only acoustically sufficient but also cost effective. The volume draws somewhat on the 1971 Noise and vibration control, edited by one of the present authors, but entirely new are chapters on the control of noise by active devices, and the quieting of internal combustion engines, electrical machinery, and gears.

Book Description -- Modal and Spectrum Analysis Data Dependent Systems in State Space Sudhakar M. Pandit Written for scientists and engineers dealing with real data?experimental or operational?this important work presents a untried and comparative treatment of modal and spectrum analysis of dynamic systems and structures. The book illustrates how the use of Data Dependent Systems (DDS) unites the two methods of analysis and simplifies many of the techniques, while providing more accurate, realistic, and easily interpreted results. Both time (modal analysis) and frequency domain (spectrum analysis) methods are systematically covered to demonstrate the relative merits and disadvantages of each. Supplements include extensive tables of results from real data, more than 50 figures (including unique plots of multivariate spectra and transfer functions) and a detailed bibliography. 1991 (0 471-63705-X) 415 pp. Vibration Problems in Engineering Fifth Edition William Weaver, Jr., Stephen P. Timoshenko, and Donovan H. Young "A substantial revision of the previous edition?it remains a very good undergraduate text and handy reference work." ?Journal of Sound and Vibration While keeping much of Timoshenko?s classic work on vibration theory intact, this Fifth Edition features new information on powerful, modern computational techniques. Written in a style that gives concrete physical meaning to terms and equations, the current edition includes such enhancements as revised problems, examples of applications, and computer programs. Highlights include a thorough presentation of multidegree of freedom systems using flexibility and stiffness formulation; vibration of continuous systems; a new chapter on the finite-element method; plus matrix and numerical techniques for problem solving.

From the Inside Flap -- Noise and Vibration Control Engineering is a completely new, single-source guide to all aspects of noise and vibration control. It offers mechanical, acoustical, architectural, electrical and chemical engineers and students the engineering principles necessary for designing quiet conditions into industrial machinery, motors, power plant equipment, air-conditioning systems, factories, buildings, and transportation systems. Contributors are among the world's leading acoustical scientists and consultants, many associated with Bolt Beranek and Newman Inc. Assuming only a general engineering background, Noise and Vibration Control Engineering begins with an examination of acoustic basics: decibels, sound power, and the properties of the various sources that create noise. The book identifies key parameters which govern sound power output and examines how noise can be controlled at its sources. Readers learn how sound propagates outdoors, around or over barriers and in enclosed spaces such as rooms and vehicles. Noise and Vibration Control Engineering moves on to discuss the basic components of noise control: active noise control techniques, sound absorbers, mufflers, enclosures, wrappings, barriers, walls, vibration isolators and vibration damping materials and their proper use in solving common noise and vibration control problems. The book shows how to control noise caused by gas flows, ventilation systems, machines, reciprocating engines and gears. Finally, it examines to what level noise must be reduced so as not to affect work performance, enjoyment of speech, radio, TV and music at home or in public spaces or to damage hearing. In addition to offering techniques to assess problems, take measurements, and implement appropriate noise and vibration control treatments, Noise and Vibration Control Engineering contains a condensed collection of authoritative, up-to-date design information, criteria and references. Finally, it provides comprehensive information about laws and codes governing noise and its control.
About the Author -- About the editors LEO L. BERANEK is cofounder and former President of Bolt Beranek and Newman Inc., a Massachusetts-based consulting firm. A registered professional engineer, Dr. Beranek received his DSc in communications engineering from Harvard University. He serves as President of the American Academy of Arts and Sciences and is a fellow of many professional organizations, including the Acoustical Society of America and the American Physical Society. Dr. Beranek is the author of more than 150 scientific papers and seven books, including Noise and Vibration Control, Noise Reduction, and Acoustics. ISTV?N L. VR is Principal Consultant at Bolt Beranek and Newman Inc. He received his PhD with a thesis in acoustics from the Technical University of Munich, Germany. Dr. Vr is the author of more than 125 publications which include book chapters, articles, papers, and sponsored technical reports. He is a past recipient of the Senior U.S. Scientist Award of the Alexander yon Humboldt Foundation of Germany and the Crosby Field Award of the American Society of Heating, Refrigeration and Air-Conditioning Engineers.
Practical Use of Noise and Vibration Control Engineering -- The book has some very practical suggestions and formulas that can be used to control noise in real engineering problems. This it does by first reviewing the basic terms, definitions and international standards in acoustics. Several practical formulas for design of noise control systems are discussed and given in the text. Formulas for calculation of sound propagation in various practical situations are also given. I recommend this book to people who have an interest in reducing noise in most practical problems. The book is also suitable to students in mechanical, aerospace, automotive, electrical, environmental, highways and building engineering who have an interest in acoustics or noise control problems. The book is however not suitable as a class textbook as not many formulas are derived neither are there many worked examples or tutorial problems that can assist a student to prepare for examinations.
