Download or read book Theory and Applications of Spherical Microphone Array Processing written by Daniel P. Jarrett and published by Springer. This book was released on 2016-08-26 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the signal processing algorithms that have been developed to process the signals acquired by a spherical microphone array. Spherical microphone arrays can be used to capture the sound field in three dimensions and have received significant interest from researchers and audio engineers. Algorithms for spherical array processing are different to corresponding algorithms already known in the literature of linear and planar arrays because the spherical geometry can be exploited to great beneficial effect. The authors aim to advance the field of spherical array processing by helping those new to the field to study it efficiently and from a single source, as well as by offering a way for more experienced researchers and engineers to consolidate their understanding, adding either or both of breadth and depth. The level of the presentation corresponds to graduate studies at MSc and PhD level. This book begins with a presentation of some of the essential mathematical and physical theory relevant to spherical microphone arrays, and of an acoustic impulse response simulation method, which can be used to comprehensively evaluate spherical array processing algorithms in reverberant environments. The chapter on acoustic parameter estimation describes the way in which useful descriptions of acoustic scenes can be parameterized, and the signal processing algorithms that can be used to estimate the parameter values using spherical microphone arrays. Subsequent chapters exploit these parameters including in particular measures of direction-of-arrival and of diffuseness of a sound field. The array processing algorithms are then classified into two main classes, each described in a separate chapter. These are signal-dependent and signal-independent beamforming algorithms. Although signal-dependent beamforming algorithms are in theory able to provide better performance compared to the signal-independent algorithms, they are currently rarely used in practice. The main reason for this is that the statistical information required by these algorithms is difficult to estimate. In a subsequent chapter it is shown how the estimated acoustic parameters can be used in the design of signal-dependent beamforming algorithms. This final step closes, at least in part, the gap between theory and practice.
Download or read book Fundamentals of Spherical Array Processing written by Boaz Rafaely and published by Springer. This book was released on 2018-09-27 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to the theory and practice of spherical microphone arrays, and was written for graduate students, researchers and engineers who work with spherical microphone arrays in a wide range of applications. The new edition includes additions and modifications, and references supplementary Matlab code to provide the reader with a straightforward start for own implementations. The book is also accompanied by a Matlab manual, which explains how to implement the examples and simulations presented in the book. The first two chapters provide the reader with the necessary mathematical and physical background, including an introduction to the spherical Fourier transform and the formulation of plane-wave sound fields in the spherical harmonic domain. In turn, the third chapter covers the theory of spatial sampling, employed when selecting the positions of microphones to sample sound pressure functions in space. Subsequent chapters highlight various spherical array configurations, including the popular rigid-sphere-based configuration. Beamforming (spatial filtering) in the spherical harmonics domain, including axis-symmetric beamforming, and the performance measures of directivity index and white noise gain are introduced, and a range of optimal beamformers for spherical arrays, including those that achieve maximum directivity and maximum robustness are developed, along with the Dolph–Chebyshev beamformer. The final chapter discusses more advanced beamformers, such as MVDR (minimum variance distortionless response) and LCMV (linearly constrained minimum variance) types, which are tailored to the measured sound field.

Download or read book Investigation of the Element Pattern in Cylindrical Phased Arrays of Circular Waveguides written by Quirino Balzano and published by . This book was released on 1972 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The radiation from the elements in a cylindrical phased array is analyzed theoretically and experimentally. The theoretical investigation has developed a multimodal analysis method for cylindrical arrays. The method is similar to that for plane arrays, whereby, the field inside the element is represented as the superposition of a set of waveguide modes. The method allows the definition and the precise evaluation of the driving point admittance of the elements. A comparison between the driving point admittance in planar and cylindrical arrays is made and the conditions for the use of Wheeler simulators for cylindrical array element design are set. (Author).

Download or read book Practice Theory and Education written by Julianne Lynch and published by Routledge. This book was released on 2016-11-25 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practice Theory and Education challenges how we think about ‘practice’, examining what it means across different fields and sites. It is organised into four themes: discursive practices; practice, change and organisations; practising subjectivity; and professional practice, public policy and education. Contributors to the collection engage and extend practice theory by drawing on the legacies of diverse social and cultural theorists, including Bourdieu, de Certeau, Deleuze and Guattari, Dewey, Latour, Marx, and Vygotsky, and by building on the theoretical trajectories of contemporary authors such as Karen Barad, Yrjo Engestrom, Andreas Reckwitz, Theodore Schatzki, Dorothy Smith, and Charles Taylor. The proximity of ideas from different fields and theoretical traditions in the book highlight key matters of concern in contemporary practice thinking, including the historicity of practice; the nature of change in professional practices; the place of discursive material in practice; the efficacy of refiguring conventional understandings of subjectivity and agency; and the capacity for theories of practice to disrupt conventional understandings of asymmetries of power and resources. Their juxtaposition also points to areas of contestation and raises important questions for future research. Practice Theory and Education will appeal to postgraduate students, academics and researchers in professional practice and education, and scholars working with social theory. It will be of particular interest to those who wish to move beyond the limiting configurations of practice found in contemporary neoliberal, new managerialist and narrow representationalist discourses.
