Previously, microphone arrays were used extensively used in beam-forming and estimation of source direction in speech enhancement problems. In Acoustic Array Systems: Theory, Implementation, and Application, the authors cover two other relatively less addressed problems: noise source identification and sound field visualization.  Specifically, using these techniques, one is able to locate and even quantify noise sources.  In addition, sound field distribution can be “visualized” by calculating the acoustical variables: pressure, particle velocity, and sound intensity. With comprehensive treatment of microphone arrays, the book covers an introduction to the theory, far-field and near-field array signal processing algorithms, practical implementations, and common applications, such as vehicles, computing and communications equipment, compressors, fans, and household appliances. The authors conclude with other emerging techniques and innovative algorithms.

This book is ideal for postgraduates and researchers in acoustics, noise control engineering, audio engineering, and signal processing. It will also be helpful to practicing engineers in automotive, information, telecommunications, consumer electronics, cloud computing, and aerospace industries.
