Download or read book Adaptive Feed Forward Control of Low Frequency Interior Noise written by Thomas Kletschkowski and published by Springer Science & Business Media. This book was released on 2011-10-29 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a mechatronic approach to Active Noise Control (ANC). It describes the required elements of system theory, engineering acoustics, electroacoustics and adaptive signal processing in a comprehensive, consistent and systematic manner using a unified notation. Furthermore, it includes a design methodology for ANC-systems, explains its application and describes tools to be used for ANC-system design. From the research point of view, the book presents new approaches to sound source localization in weakly damped interiors. One is based on the inverse finite element method, the other is based on a sound intensity probe with an active free field. Furthermore, a prototype of an ANC-system able to reach the physical limits of local (feed-forward) ANC is described. This is one example for applied research in ANC-system design. Other examples are given for (i) local ANC in a semi-enclosed subspace of an aircraft cargo hold and (ii) for the combination of audio entertainment with ANC.

Download or read book Adaptive IIR Filtering in Signal Processing and Control written by Phillip Regalia and published by Routledge. This book was released on 2018-04-27 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrates rational approximation with adaptive filtering, providing viable, numerically reliable procedures for creating adaptive infinite impulse response (IIR) filters. The choice of filter structure to adapt, algorithm design and the approximation properties for each type of algorithm are also addressed. This work recasts the theory of adaptive IIR filters by concentrating on recursive lattice filters, freeing systems from the need for direct-form filters.;A solutions manual is available for instructors only. College or university bookstores may order five or more copies at a special student price which is available upon request.
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.
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 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.
