Book A Simplified Hybrid Active Noise Control Algorithm for Commercial Headset Applications

Download or read book A Simplified Hybrid Active Noise Control Algorithm for Commercial Headset Applications written by Siddharth Raghunandan and published by . This book was released on 2016 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This paper proposes a simplified hybrid adaptive feedback algorithm along with design constraints for active noise control in open-backed commercial headsets. It is physically improbable in practice to achieve complete noise cancellation, especially in open backed conditions. This inherent property suggests that the residual noise can be used as a reference signal directly to adapt a leaky feedback FxLMS algorithm. A fixed analog feedback controller is concatenated into the FxLMS system, whose design constraints are derived from existing feedback based active and passive control systems. The resulting simplified hybrid algorithm using analog elements and digital elements, provides adequate noise control of both broadband and narrowband ranges, remaining robustly stable in open-backed plant changes throughout. A lighter computational load along with ease of implementation is also accomplished. The proposed algorithm's feasibility and relative performance are compared with other variants in a simulated acoustic environment using MATLAB's Audio Stream Processing Toolbox.

Book Automatic Control Robotics and Information Processing

Download or read book Automatic Control Robotics and Information Processing written by Piotr Kulczycki and published by Springer Nature. This book was released on 2020-09-03 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a wide and comprehensive range of issues and problems in various fields of science and engineering, from both theoretical and applied perspectives. The desire to develop more effective and efficient tools and techniques for dealing with complex processes and systems has been a natural inspiration for the emergence of numerous fields of science and technology, in particular control and automation and, more recently, robotics. The contributions gathered here concern the development of methods and algorithms to determine best practices regarding broadly perceived decisions or controls. From an engineering standpoint, many of them focus on how to automate a specific process or complex system. From a tools-based perspective, several contributions address the development of analytic and algorithmic methods and techniques, devices and systems that make it possible to develop and subsequently implement the automation and robotization of crucial areas of human activity. All topics discussed are illustrated with sample applications.

Book Adaptive Feed Forward Control of Low Frequency Interior Noise

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.

Book Active noise cancellation headset

Download or read book Active noise cancellation headset written by and published by . This book was released on with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, a new design for headset with active noise cancellation capability is presented. For the proposed headset, a Variable-Step-Size Normalized Least-Mean-Square (VSS-NLMS) algorithm is adopted in the combined audio and feedback active noise cancellation system. Experimental results show that for the same set of signals, the average noise reduction using the proposed adaptive algorithms is 38dB compared with 36dB using Normalized Least-Mean-Square algorithm and 14 dB using the Least-Mean-Square algorithm. The speed of convergence using the proposed approach is also faster compared with the other two cases. Informal listening tests also favor the adoption of the proposed VSS-NLMS adaptive algorithm.

Book Understanding Active Noise Cancellation

Download or read book Understanding Active Noise Cancellation written by Colin N. Hansen and published by CRC Press. This book was released on 2002-05-03 with total page 173 pages. 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.

Book Active Control of Sound

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.

Book Noise Reduction in Speech Applications

Download or read book Noise Reduction in Speech Applications written by Gillian M. Davis and published by CRC Press. This book was released on 2018-10-03 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise and distortion that degrade the quality of speech signals can come from any number of sources. The technology and techniques for dealing with noise are almost as numerous, but it is only recently, with the development of inexpensive digital signal processing hardware, that the implementation of the technology has become practical. Noise Reduction in Speech Applications provides a comprehensive introduction to modern techniques for removing or reducing background noise from a range of speech-related applications. Self-contained, it starts with a tutorial-style chapter of background material, then focuses on system aspects, digital algorithms, and implementation. The final section explores a variety of applications and demonstrates to potential users of the technology the results possible with the noise reduction techniques presented. The book offers chapters contributed by international experts, a practical, systems approach, and numerous references. For electrical, acoustics, signal processing, communications, and bioengineers, Noise Reduction in Speech Applications is a valuable resource that shows you how to decide whether noise reduction will solve problems in your own systems and how to make the best use of the technologies available.
