The forces and motions within machines are the source of sound and vibration produced by the machine. This book discusses how various mechanisms such as gears, electromagnetics, flow, and combustion produce forces and motions, how the machine responds to this excitation, and how the resulting vibrations radiate sound. The book also discusses how these sounds and vibrations can be used to determine the mechanical condition of the machine, and the signal processing methods that are used.

About the Author
Dr. Richard H. Lyon has been working in the field of acoustics, vibrations, and dynamics since the early 1950's. After completing his undergraduate work at Evansville College, Dr. Lyon entered MIT as a physics graduate student in September 1952. He did his Ph.D. thesis research under Prof. K. U.Ingard on the turbulent excitation of strings. In his final student year at MIT, he was elected to Sigma Xi, and held the Owens-Corning Fellowship in Acoustics. He received the Ph.D. in physics from MIT in June 1955.
After one year as a research staff member at MIT, R. Lyon joined the Electrical Engineering Department of the University of Minnesota as an Assistant Professor. He taught courses in acoustics, circuit theory and random processes and carried out research on flow stability and random vibration. In June 1959 he was promoted to Associate Professor.
In September 1960 he joined the staff of Bolt Beranek and Newman Inc. of Cambridge, Mass. He worked on problems of sound-structure interaction and excitation of structures by turbulence for industry, NASA and the Department of Defense. In 1964 he became Department Head and in 1967 he became a Division Director and Corporate Vice President.
In 1970 he joined MIT as Professor of Mechanical Engineering. At MIT he led research in noise propagation and machinery noise and taught courses in basic and applied acoustics. Each summer, he teaches a course in designing products for better sound quality to engineers from industry. Dr. Lyon retired from MIT in July 1995 and moved full time into RH Lyon Corp in Cambridge, MA.
The business of RH Lyon Corp is concerned with the design and diagnostics of products, primarily with regard to sound and vibration. The clients of the company have been primarily from the consumer and office products industries, including Maytag, Whirlpool, General Motors, Ford, Xerox, HP, General Electric, Scott & Fetzer, Thomson Consumer Electronics, Bosch, Raytheon, Kimberly-Clark, and Westinghouse.

5.0 out of 5 stars
A great book that gave me deep physical understanding,

This review is from: Machinery Noise and Diagnostics (Hardcover)
This book has no similarity with other books in mechanical vibration field. As the author is the father of Statistical Energy Analysis, this book sometimes looks noise and vibration phenomena from the viewpoints of energy generation and transmission. This view will surely provide readers who are fed up with conventional structural vibration theory with new idea of solving the problems they have at hand. Some topics in the chapter 8, "Advanced Topis in Diagnostics", is worth reading for even very experienced engineers in this field. What I regret is that almost all the examples lack in-detail descriptions. To read this book, readers are recommended to have electric circuit theory, knowledge of statisticsTheory and Application of Statistical Energy Analysis and digital signal processing.Digital Signal Processing
