Download or read book Sound Pulses written by F. G. Friedlander and published by Cambridge University Press. This book was released on 2009-07-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large number of text books on the theory of sound deal principally with periodic disturbances such as harmonic wave trains and standing waves and give scant attention to aperiodic disturbances with clearly defined fronts, conveniently called sound pulses. This monograph attempts to fill this gap by providing an up-to-date description of the theory of sound pulses and its developments. The treatment is based on the thoery of linear partial differential equations of hyperbolic type - a method which is frequently simpler and more effective than the commoner one of resolving the pulse into harmonic components by Fourier analysis; this is especially true of any treatment of pulse fronts as wave fronts in the sense of geometrical optics. The individual chapters deal with the equations of motion, wave fronts and characteristics, geometrical acoustics and their application to reflection problems and the diffraction of a pulse by a wedge, circular cylinder, sphere and other objects. The book will also be of interest to readers concerned with other aspects of wave propagation, such as electromagnetic waves.
Download or read book High Frequency and Pulse Scattering written by Allan D. Pierce and published by Academic Press. This book was released on 2013-10-22 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Frequency and Pulse Scattering investigates high frequency and pulse scattering, with emphasis on the phenomenon of echoes from objects. Geometrical and catastrophe optics methods in scattering are discussed, along with the scattering of sound pulses and the ringing of target resonances. Caustics and associated diffraction catastrophes are also examined. Comprised of two chapters, this volume begins with a detailed account of geometrically based approximation methods in scattering theory, focusing on waves transmitted through fluid and elastic scatterers and glory scattering; surface ray representations of scattering by shells and other smooth objects; and caustics and associated diffraction catastrophes. The second chapter deals with the relation between sound pulses and the vibrational spectra of elastic submerged objects. The theory of the scattering of sound pulses from elastic and impenetrable objects is described, together with the theory of surface wave pulses. Target resonances and the singularity expansion method are also analyzed. This book will be of interest to physicists.
Download or read book Echocardiology written by N. Bom and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Echocardiology comprises all aspects of diagnostic application of ultrasound to cardiac patients. It is probably the fastest growing non-invasive technique today. Almost all progress in this young and exciting field has been the positive result of close co-operation between medical and technical scientists. This book contains a series of lectures held at Erasmus University Rotterdam in June 1977 and is divided in three sections: - clinical echocardiology, consisting of both an introduction to the basic principles as well as a wide variety of applications aimed at the clinically oriented reader. - Doppler methods, where in addition to its clinical applications also the engineering of new developments will be presented. - the two dimensional real-time imaging where many new techniques including com puter methods, holography and acousto-optical systems will be discussed. We hope that this book will stimulate communication between scientists of various disciplines and nationalities. N.Bom J. Roelandt P.G. Hugenholtz Rotterdam, June 1977 III Preface The last three decades have seen a remarkable advance in diagnostic instrument ation in diseases of the circulation. In the 1940's the only diagnostic aids were the electrocardiogram and simple X-ray. These were quickly followed by the cardiac ca theter, phonocardiography, radio isotope methods and angiocardiography. The de velopment of cardiac surgery provided the impetus to developing more accurate methods of diagnosis, preferably those that did not need invasion of the patient. The introduction of ultrasound has contributed towards this aim in the last few years.

Download or read book Reminded by the Instruments written by You Nakai and published by Oxford University Press. This book was released on 2021-03-09 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: David Tudor is remembered today in two guises: as an extraordinary pianist of post-war avant-garde music who worked closely with composers like John Cage and Karlheinz Stockhausen and as a founding figure of live-electronic music. His early realization of indeterminate graphic scores and his later performances using homemade modular instruments both inspired a whole generation of musicians. But his reticence, his unorthodox approaches, and the diversity of his creative output which began with the organ and ended with visual art have kept Tudor a puzzle. Illustrated with more than 300 images of diagrams, schematics, and photographs of Tudor's instruments, Reminded by the Instruments sets out to solve the puzzle of David Tudor by applying Tudor's own methods for approaching the materials of others to the vast archive of materials that he himself left behind. You Nakai deftly patches together instruments, electronic circuits, sketches, diagrams, recordings, letters, receipts, customs declaration forms, and testimonies like modular pieces of a giant puzzle to reveal the long-hidden nature of Tudor's creative process. Rejecting the established narrative of Tudor as a performer-turned-composer, this book presents a lively portrait of an artist whose activity always merged both of these roles. In reading Tudor's electronic devices as musicological 'texts' and examining his idiosyncratic use of electronic circuits, Nakai undermines discourses on sound and illuminates our understanding of the instruments behind the sounds in post-war experimental music.
Download or read book Echolocation in Bats and Dolphins written by Jeanette A. Thomas and published by University of Chicago Press. This book was released on 2004 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although bats and dolphins live in very different environments, are vastly different in size, and hunt different kinds of prey, both groups have evolved similar sonar systems, known as echolocation, to locate food and navigate the skies and seas. While much research has been conducted over the past thirty years on echolocation in bats and dolphins, this volume is the first to compare what is known about echolocation in each group, to point out what information is missing, and to identify future areas of research. Echolocation in Bats and Dolphins consists of six sections: mechanisms of echolocation signal production; the anatomy and physiology of signal reception and interpretation; performance and cognition; ecological and evolutionary aspects of echolocation mammals; theoretical and methodological topics; and possible echolocation capabilities in other mammals, including shrews, seals, and baleen whales. Animal behaviorists, ecologists, physiologists, and both scientists and engineers who work in the field of bioacoustics will benefit from this book.

Available in PDF, EPUB and Kindle. Book excerpt: Physical and Applied Acoustics: An Introduction explores the mechanical-acoustical or acoustical-electrical analogies that are based on common theoretical relationships. This book is composed of 11 chapters that discuss the theory, experiment, and technological applications of physical and applied acoustics. The introductory chapters deal with the sound wave propagation in liquids and gases, as well as the statistical theory of room acoustics. These topics are followed by discussions on sound absorption in different medium; the concept of sound radiation pressure; directional characteristics of sound sources; measurement and calibration of acoustics; and the fundamental physical and psychological facts of acoustics. The subsequent chapters cover the use of electroacoustics for the transmission of speech and music. A chapter examines the production and detection of extremely high-frequency sound, called quantum acoustics. The concluding chapter highlights the interaction phenomena between sound and flow in a medium.

Download or read book Digital Audio Restoration written by Simon J. Godsill and published by Springer. This book was released on 2013-12-21 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of digital signal processing (DSP) to problems in audio has been an area of growing importance since the pioneering DSP work of the 1960s and 70s. In the 1980s, DSP micro-chips became sufficiently powerful to handle the complex processing operations required for sound restoration in real-time, or close to real-time. This led to the first commer cially available restoration systems, with companies such as CEDAR Audio Ltd. in the UK and Sonic Solutions in the US selling dedicated systems world-wide to recording studios, broadcasting companies, media archives and film studios. Vast amounts of important audio material, ranging from historic recordings of the last century to relatively recent recordings on analogue or even digital tape media, were noise-reduced and re-released on CD for the increasingly quality-conscious music enthusiast. Indeed, the first restorations were a revelation in that clicks, crackles and hiss could for the first time be almost completely eliminated from recordings which might otherwise be un-releasable in CD format. Until recently, however, digital audio processing has required high-powered computational engines which were only available to large institutions who could afford to use the sophisticated digital remastering technology. With the advent of compact disc and other digital audio formats, followed by the increased accessibility of home computing, digital audio processing is now available to anyone who owns a PC with sound card, and will be of increasing importance, in association with digital video, as the multimedia revolution continues into the next millennium.

This book was released on 2008 with total page 1103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Key Message:This book aims to explain physics in a readable and interesting manner that is accessible and clear, and to teach readers by anticipating their needs and difficulties without oversimplifying. Physics is a description of reality, and thus each topic begins with concrete observations and experiences that readers can directly relate to. We then move on to the generalizations and more formal treatment of the topic. Not only does this make the material more interesting and easier to understand, but it is closer to the way physics is actually practiced.
