Recent technological advances in the development of fast digital signal processors have made the active control of sound a practical proposition. This book brings together results from research in the two disciplinesof acoustics and signal processing and presents the fundamentals of noise control in a unified manner. Practical applications are presented wherever possible although the emphasis is on the algorithmic principles which form the foundation of practical systems. The volume is written in textbook style and aimed at both undergraduate and postgraduate students of acoustics and signal processing, professional acoustical and electrical engineers, and researchers in the field of active control.

Review quote

A most important text, which brings both the underlying theory and practical technique within clear reach of their intended audience: students in acoustics and signal processing, professional acoustical and electrical engineers and researchers studying active sound control....The clear, well-written and informative coverage of this and other topics makes the book a joy to read....This book is essential reading for those participating in the technology of antisound, a technology that can work where other methods fail. That aspect should give the subject a bright future, a future brought closer by the clarity of Active Control of Sound. --PHYSICS TODAY
