Book Description
Active noise control (ANC) is rapidly becoming the most effective way to reduce noises that can otherwise be very difficult and expensive to control. ANC is achieved by introducing a canceling "anti-noise" wave through an appropriate array of secondary sources. When applied accurately, ANC can provide effective solutions to noise-related problems in a broad range of areas, including manufacturing and industrial operations as well as consumer products. Consequently, ANC research and development has become an important focus of both industrial applications and engineering research.

Active Noise Control Systems: Algorithms and DSP Implementations introduces the basic concepts of ANC with an emphasis on digital signal processing (DSP) hardware and adaptive signal processing algorithms, both of which have come into prominence within the last decade. The authors emphasize the practical aspects of ANC systems by combining the principles of adaptive signal processing with both experimental results and practical implementation. Applications are cited in many fields and encompass all types of noise media, including air-acoustic, hydroacoustic, vibrations, and others. The specific implementation stressed is based on the TMS320 family of signal processors from Texas Instruments, which are the most widely used worldwide.

Coverage of theory includes concise derivations and analyses of commonly used adaptive structures and algorithms for active noise control applications, which are enhanced by the inclusion of a floppy disk featuring C and assembly programs for implementing many ANC systems. Mathematical representations are employed and the source code included on the disk is in a form that is easily accessible to anyone using the book.

For practicing engineers, researchers, and advanced students in signal processing, Active Noise Control Systems: Algorithms and DSP Implementations will serve as a comprehensive, state-of-the-art text/reference on this important and rapidly developing field.

The recent development of digital signal processing (DSP) hardware and adaptive signal processing algorithms has resulted in a dynamic new way of achieving active noise control (ANC). To meet the need for a definitive text on both the basic theory and practical applications of these new ANC techniques, Sen M. Kuo and Dennis R. Morgan have written an invaluable, highly accessible book for researchers, engineers, and advanced students in signal processing.

Review from signal processing View
This is an excellent book for persons with signal processing background. The book provides only minimum information about acoustics for a signal processing person and does not confuse with too much of details. In this way, the book makes to reader comfortable. Also many aspects of signal processing which can improve the performance of an active noise control (ANC)system are explainedand hence the reader feels more confident that he too can work in this field. This is very much essential as the adaptive algorithms play a crucial role in the ANC implementation. The FXLMS algorithm and its problems are well described. To start with I did not know any thing about ANC, but this book has helped me to get good understanding about it. Presnently, I am able to do research contributions to international journal and to conferences. Further, I have taken up projects at national level in ANC. I feel this book has presented the subject in a simple wayretaining all the intricate details. This background enablesa reseacher even to follow new developments taking place in this filed.This is a very very useful and excellent book.

review from signal processing view
This is an excellent book for the signal processing community as the stress is mainly on algorithms and implementation. A reseacher who wants to work in this field without much background in acoustics, finds this book very useful and it enables him to get to know how he can apply his adaptive signal processing skills to active noise control.This book provides in a simple way the active noise control field and its associated problems. As the book provides only required amount of acoustical details and explains the filtered LMS algorithm very clearly unlike other books, for a beginer it is a very good book. I didn't know any thing aboout ANC when I started, but to day I am able to contribute even to internationaljournals and conferences.Further I have under taken projects at national level from government agencies to develop ANC systems.I feel this book is really well written and it makes the readerkeen to know about the subject and provides him high level of confidence.I sincerely recommend this book for any person who is new to this field and has signal processing background. It is a very very very excellent book.

The best reference for ANC algorithms
This excellent text is written for advanced study and practicing engineers who need to design controllers for active noise control systems. The emphasis is on the algorithms that are usually implemented in a DigitalSignal Processor. The book's treatment of acoustics, sensors, and actuatorsis not as in-depth as texts by Fuller or Nelson. Included in the book is Cand assembly code for the most popular adaptive control techniques, butbeware of bugs and patent issues. One of the algorithms covered in detailis the Filtered-X Least Mean Squares technique that one of the Authors(Morgan) help to make popular in the community.

Book Description
Active noise control - the reduction of noise by generating an acoustic signal that actively interferes with the noise - has become an active area of basic research and engineering applications. The aim of this book is to present all of the basic knowledge one needs for assessing how useful active noise control will be for a given problem and then to provide some guidance for designing, setting up, and tuning an active noise-control system. Written for students who have no prior knowledge of acoustics, signal processing, or noise control but who do have a reasonable grasp of basic physics and mathematics, the book is short and descriptive. It leaves for more advanced texts or research monographs all mathematical details and proofs concerning vibrations, signal processing and the like. The book can thus be used in independent study, in a classroom with laboratories, or in conjunction with a kit for experiment or demonstration. Topics covered include: basic acoustics; human perception and sound; sound intensity and related concepts; fundamentals of passive noise-control strategies; basics of digital systems; basics of adaptive controllers; and active noise control systems. ...

Book Description
The prospect of the active control of noise has intrigued, and frustrated, scientists and engineers in many countries for over five decades. The basic idea is relatively simple: to artificially generate a secondary acoustic field that destructively interferes with the field produced by the
unwanted sound. However the limitations of the available electronic technology have restricted practical realization to a few simple applications.With the development of flexible and cheap digital signal processing devices, capable of processing signals within the audio range, there has been a
resurgence in interest in the theory and practice of developing active noise control systems. Further, the flexibility of these devices allows the developer to concentrate on the design procedure and corresponding control algorithms, rather than the acoustic properties of the arrangements. This book
provides an introduction to the design of such systems from the perspective of control engineering.The approach allows the designer to predict the performance of the system in advance and reduces the empirical aspect of many previous approaches. The use of control engineering methods moreover
permits the progressive development of various control techniques--from fixed digital control to self-tuning adaptive control--to be realized within a single coherent framework. ... Read more

Book Description
Noise and vibration are known to have adverse physiological and psychological effects as well as their deleterious consequences for engineering concerns as disparate as signal quality and ride comfort. Accordingly, researchers have investigated the development of various methods for noise reduction and vibration suppression. It is now time for the fruits of this research to be made easily accessible to students. With these goals in mind, Active Noise and Vibration Control shows you how to analyse and design control systems from an engineering perspective. This approach teaches you to predict the performance of a system in advance, reducing the empirical aspects of design. Making use of control engineering concepts, your skills in dealing with noise and vibration will develop from fixed digital control through self-tuning adaptive control to the incorporation of neural networks and genetic algorithms within a single intelligent control framework. Featuring:Consideration of design complexity and realisability in relation to given system configurations.Illustrations and worked examples throughout the body of the book that demonstrate its concepts of intertwined analysis and design together with end-of-chapter exercises and further reading lists to drive home points made in the text.Associated software environments based on Matlab®/Simulink® available on-line that allow you first to simulate noise and vibration patterns in different media and then to realise and assess your own control designs.An essential study aid for graduate students of systems and control engineering, signal processing, communications, acoustics and vibration, Active Noise and Vibration Control will also interest industrial developers of equipment associated with these disciplines. Final-year undergraduates in related subjects should also find much to assist them in this text. ... Read more
