Available in PDF, EPUB and Kindle. Book excerpt: Understanding Active Noise Cancellation Provides a concise introduction to the fundamentals and applications of active control of vibration and sound for the non-expert. It is also a useful quick reference for the specialist engineer. The book emphasises the practical applications of technology, and complex control algorithms and structures are only discussed to the extent that they aid understanding. Extensive recommendations for further reading on the subject are provided, but the text will stand alone for those seeking an overview of the key issues: fundamentals, control systems, transducers, applications and possible future directions.

Download or read book Active Control of Sound written by P. A. Nelson and published by . This book was released on 1993 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. A key feature of the work is the unified presentation of material from the two disciplines of acoustics and signal processing.

Download or read book Adaptive Algorithms for Active Noise and Vibration Control written by and published by . This book was released on 2000 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project was to develop and analyze advanced adaptive schemes for the active attenuation of sound and vibration. Implementations of algorithms such as the filtered-X LMS algorithm were proposed that require fewer computations than the standard implementation. Delay compensation techniques were also developed to combat performance reducing effects due to delay within the parameter updates. In particular, the extension of the method to adaptive echo cancellation was investigated. Progress was also made on adaptive algorithms for the rejection of periodic disturbances without measurement of the disturbance or of its frequency. A direct approach and an indirect approach were studied, and the resulting algorithms were tested successfully on an active noise control testbed. Disturbances with multiple harmonics and multi-channel systems were both considered.

Download or read book Active Noise Control Primer written by Scott D. Snyder and published by Springer Science & Business Media. This book was released on 2012-09-25 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: By providing all the basic knowledge needed to assess how useful active noise control will be for a given problem, this book assists in the designing, setting up, and tuning of 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 text is short and descriptive, leaving all mathematical details and proofs concerning vibrations, signal processing and the like to more advanced texts or research monographs. 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 and adaptive controllers, and active noise control systems.

Download or read book Active Noise Cancellation Using Selective Adaptive Filtering written by Oveal Walker and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intelligibility of speech and other audio in various acoustic environments can be very low based on the level of noise present in that space. Often in order to compensate for the noise in acoustic environments a passive approach is taken, in which sound absorption and isolation techniques are implemented throughout the physical space. Although this passive approach can provide suitable levels of noise reduction for a reasonable range of frequencies, several active noise control approaches are proven to be more effective, especially at frequencies below 500 Hz. Active Noise Control utilizes adaptive filtering algorithms to achieve significant noise attenuation of lower frequency noise that significantly degrades the desired audio signal. The level of effectiveness of various adaptive filtering algorithms can determine the overall noise attenuation and the rate at which the system attenuates the noise in the given space. Noise source location, level, and resonant space may dictate the amount of degradation caused on the input signal. Some acoustic spaces in which Active Noise Cancellation (ANC) headsets are used causes increasing resonance and inconsistent changes in noise power and amplitude. Special consideration of these signal characteristics are used to determine the stationary level of the noise signal, which is an ideal measure for determination of an adaptive filtering algorithm. Most Active Noise Control systems currently utilize only versions of the Least Mean Square adaptive filtering algorithm. This research will focus on a selective algorithm that will utilize descriptors to identify differences in the noise signal, and determine an optimal algorithm to be used for the filtering of distinct portions of the signal that are identified. The Recursive Least Squares adaptive algorithm will be used as the primary means of filtering due to its fast rate of convergence and tracking performance. A selective switching mechanism will be used to insure the Least Mean Squares algorithm is initiated only when signal conditions dictate effective noise control can be performed using this algorithm. Several different noise source environments are tested in order to attain the best active noise control solution to be used.

Available in PDF, EPUB and Kindle. Book excerpt: This second edition of Adaptive Filters: Theory and Applications has been updated throughout to reflect the latest developments in this field; notably an increased coverage given to the practical applications of the theory to illustrate the much broader range of adaptive filters applications developed in recent years. The book offers an easy to understand approach to the theory and application of adaptive filters by clearly illustrating how the theory explained in the early chapters of the book is modified for the various applications discussed in detail in later chapters. This integrated approach makes the book a valuable resource for graduate students; and the inclusion of more advanced applications including antenna arrays and wireless communications makes it a suitable technical reference for engineers, practitioners and researchers. Key features: • Offers a thorough treatment of the theory of adaptive signal processing; incorporating new material on transform domain, frequency domain, subband adaptive filters, acoustic echo cancellation and active noise control. • Provides an in-depth study of applications which now includes extensive coverage of OFDM, MIMO and smart antennas. • Contains exercises and computer simulation problems at the end of each chapter. • Includes a new companion website hosting MATLAB® simulation programs which complement the theoretical analyses, enabling the reader to gain an in-depth understanding of the behaviours and properties of the various adaptive algorithms.
