Vibro-Acoustics: Fundamentals and Applications

by Dhanesh N. Manik

Overview

The subject of vibro-acoustics is important for the design of machine elements and structures, to minimize sound generated by them. For better machine designing, it is necessary for machine designers (mechanical engineers) to have a thorough knowledge of vibro-acoustics. Furthermore, since the design cycles of machines have become shorter, designers will have to design quiet machines at the drawing-board stage rather than applying "band-aid" techniques after the machine has been built.

Although there is common ground in the treatment of acoustics, the subject of vibration is not very fortunate. Those interested in low-frequency vibration are generally concerned with the modal approach of using natural frequencies and mode shapes, whereas those interested in vibro-acoustics in medium and high frequencies are generally concerned with the wave approach. Since both modal and wave approaches have their advantages, it is a good idea to study both together to get the best out of them. This is useful for a better understanding the physics of vibro-acoustics. Written for students and professionals interested in gaining knowledge, this book systematically integrates the relevant aspects of vibro-acoustics from various viewpoints.

About the Author

Dhanesh N. Manik was born in Mysore, India. He graduated with a bachelor’s degree in mechanical engineering from Mysore University in 1982, master’s degree in mechanical engineering from Indian Institute of Science (I.I.Sc.), Bangalore, in 1985, and PhD in mechanical engineering from Auburn University, U.S.A, in 1991. He has also briefly worked at Hindustan Aeronautics (Helicopter Division), Bangalore, from 1985 to 1986. He joined the faculty of Indian Institute of Technology Bombay (IITB) in 1992 and is currently a professor in mechanical engineering. His main areas of research are statistical energy analysis (SEA) and machinery diagnostics. He is a member of the International Institute of Acoustics and Vibration, Acoustical Society of India and National Committee on Noise Pollution Control, Central Pollution Control Board, India. He is a consultant to many projects from industry related to vibration and noise and regularly conducts continuing education programs to industry professionals on vibration and noise. He has authored the book on control systems (Cengage India 2012).

Editorial Reviews

"Professor Manik has made the book comprehensive as well as self-contained. It can be used by any mechanical engineer for self-reading and does not require any prior reading or lateral referencing. The book is strong on fundamentals and includes many solved examples for the illustrations."
— M L Munjal (Emeritus), Indian Institute of Science, Bengaluru, India

The nice thing about the book is that it is laid out in a good and understandable sequence. I would suspect students using this as a text with skilled instruction would be well-prepared to use and understand the existing commercial software if not to tackle and solve problems mathematically. For practitioners, it will serve as a reference. I really like this book. This book clarifies the understanding and modeling of sound radiation by vibrating structural components and systems, which is very important for vibrating systems, including transducers, and noise control design. Highly recommended.
