Synopsis

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.

• Presents the fundamental principles governing both the physical properties of sound fields and modern digital techniques for processing acoustic signals
• Describes the physical mechanisms and energy interchanges involved in active control of sound for one- and three-dimensional problems
• Presents the principles and practicalities of the design of single- and multi-channel controllers for both random and deterministic sound fields

About this title

Review

"This book is essential reading for those participating in the technology of antisound" --Physics Today

Synopsis

This book describes modern techniques for reducing the level of airborne noise through the introduction of sound radiated by additional "secondary" sources, bringing together the results of contemporary research in this area. It is the combination of the physical properties of sound fields and modern digital signal processing technology that has made the active control of sound a practical proposition in a number of important applications. The book covers both these aspects of the subject, initially at a fundamental level, and then in detail in later chapters. The structure of the book is such that it should be suitable for both those seeking a basic understanding of the subject and as a reference for researchers in the field. One of the key features of the work is thus the unified presentation of material from the two disciplines of acoustics and signal processing.
