CU Press, 1998. 570 p. ISBN: 0521633206, 9780511662898, 9780521633208, 9780521054287
Transferred to digital printing 2004This book provides the basis for all calculations necessary for the determination of sound generation by aircraft, ships, general ventilation and combustion systems, as well as musical instruments. Both a graduate textbook and a reference for researchers, this book is an important synthesis of information in this field. It will also aid engineers in the theory and practice of noise control.This book presents useful background material on fluid mechanics and the elementary concepts of classical acoustics and structural vibrations. Using examples, many of which include complete worked solutions, he vividly illustrates the theoretical concepts involved.Fluids, structures, and acoustics
