This book deals with the way that the auditory system processes acoustic signals. The current edition has been revised in all areas to reflect the progress that has been made since the 3rd edition. As well as dealing with the basic anatomy and physiology of all stages of the auditory system, the book relates basic physiological processes to the performance of the auditory system as a whole, in the perception of acoustic signals including speech. The chapter on sensorineural hearing loss not only describes the physiological and anatomical changes that are associated with hearing loss, but includes latest information on treatments including cochlear implants, and work being undertaken on stem cell and other cellular therapies for deafness. A reading scheme has been provided to guide readers to the section most appropriate for their interests. The book is written so that those entering auditory research from very little background in auditory neuroscience are able to understand the current research issues and the current research literature. It is also intended to be a source book and reference work for advanced undergraduates studying the special senses, and for clinicians in the specialty of Otorhinolaryngology.

Waves are essential phenomena in most scientific and engineering disciplines, such as electromagnetism and optics, and different mechanics including fluid, solid, structural, quantum, etc. They appear in linear and nonlinear systems. Some can be observed directly and others are not. The features of the waves are usually described by solutions to either linear or nonlinear partial differential equations, which are fundamental to the students and researchers.Generic equations, describing wave and pulse propagation in linear and nonlinear systems, are introduced and analyzed as initial/boundary value problems. These systems cover the general properties of non-dispersive and dispersive, uniform and non-uniform, with/without dissipations. Methods of analyses are introduced and illustrated with analytical solutions. Wave-wave and wave-particle interactions ascribed to the nonlinearity of media (such as plasma) are discussed in the final chapter.This interdisciplinary textbook is essential reading for anyone in above mentioned disciplines. It was prepared to provide students with an understanding of waves and methods of solving wave propagation problems. The presentation is self-contained and should be read without difficulty by those who have adequate preparation in classic mechanics. The selection of topics and the focus given to each provide essential materials for a lecturer to cover the bases in a linear/nonlinear wave course.

A practical guide to cutting-edge techniques for flow measurement and control
Unlike any other book on the subject, this volume employs practical applications to illustrate flow measurement techniques in industrial processes. Drawing on their work at the Oak Ridge National Laboratory, five leading researchers present applications that test the limits of commercial flow instrumentation-in harsh environments, wide rangeability, and a host of challenging situations encountered in research and industry. This approach gives the reader highly effective tools for use in tackling a broad range of difficult flow measurement problems. It offers tremendous insight into what flow measurement is all about, from the underlying principles of the methodologies to state-of-the-art instrumentation-including such innovations as "smart" flow sensors. Introducing terminology, properties, units, and flow meters classification, the book:
* Details signal conditioning and analysis techniques that will produce meaningful results
* Offers tips on selecting the appropriate method for a given application
* Shows how modeling can improve mass flow metering accuracy
* Covers flow calibration and standards, as well as issues related to cost, maintenance, and ease-of-use of instruments
* Addresses the effect of measurement uncertainty on calibration and field measurements.
Clear, concise, and generously illustrated, Flow Measurement Methods and Applications is an invaluable resource for researchers and graduate students in physics, mechanical engineering, chemical engineering, and instrument engineering. It is a must-have reference for anyone wishing to assess flow processes accuratelyand reliably in the real world.

The book presents a broad-scope analysis of piezoelectric electromechanical transducers and the related aspects of practical transducer design for underwater applications. It uses an energy method for analyzing transducer problems that provides the physical insight important for the understanding of electromechanical devices. Application of the method is first illustrated with transducer examples that can be modeled as systems with a single degree of freedom, (such as spheres, short cylinders, bars and flexural disks and plates made of piezoelectric ceramics). Thereupon, transducers are modeled as devices with multiple degrees of freedom. In all these cases, results of modeling are presented in the form of equivalent electromechanical circuits convenient for the calculation of the transducers' operational characteristics. Special focus is made on the effects of coupled vibrations in mechanical systems on transducer performance. The book also provides extensive coverage of acoustic radiation including acoustic interaction between the transducers. The book is inherently multidisciplinary. It provides essential background regarding the vibration of elastic passive and piezoelectric bodies, piezoelectricity, acoustic radiation, and transducer characterization. Scientists and engineers working in the field of electroacoustics and those involved in education in the field will find this material useful not only for underwater acoustics, but also for electromechanics, energy conversion and medical ultrasonics. Part II contains general information on vibration of mechanical systems, electromechanical conversion in the deformed piezoceramic bodies, and acoustic radiation that can be used independently for treatment transducers of different type.

Software Synthesis from Dataflow Graphs addresses the problem of generating efficient software implementations from applications specified as synchronous dataflow graphs for programmable digital signal processors (DSPs) used in embedded real- time systems. The advent of high-speed graphics workstations has made feasible the use of graphical block diagram programming environments by designers of signal processing systems. A particular subset of dataflow, called Synchronous Dataflow (SDF), has proven efficient for representing a wide class of unirate and multirate signal processing algorithms, and has been used as the basis for numerous DSP block diagram-based programming environments such as the Signal Processing Workstation from Cadence Design Systems, Inc., COSSAP from SynopsysA(R) (both commercial tools), and the Ptolemy environment from the University of California at Berkeley. A key property of the SDF model is that static schedules can be determined at compile time. This removes the overhead of dynamic scheduling and is thus useful for real-time DSP programs where throughput requirements are often severe. Another constraint that programmable DSPs for embedded systems have is the limited amount of on-chip memory. Off-chip memory is not only expensive but is also slower and increases the power consumption of the system; hence, it is imperative that programs fit in the on-chip memory whenever possible. Software Synthesis from Dataflow Graphs reviews the state-of-the-art in constructing static, memory-optimal schedules for programs expressed as SDF graphs. Code size reduction is obtained by the careful organization of loops in the target code. Data buffering is optimized byconstructing the loop hierarchy in provably optimal ways for many classes of SDF graphs. The central result is a uniprocessor scheduling framework that provably synthesizes the most compact looping structures, called single appearance schedules, for a certain class of SDF graphs. In addition, algorithms and heuristics are presented that generate single appearance schedules optimized for data buffering usage. Numerous practical examples and extensive experimental data are provided to illustrate the efficacy of these techniques.

Quantum Theory, together with the principles of special and general relativity, constitute a scientific revolution that has profoundly influenced the way in which we think about the universe and the fundamental forces that govern it. The Historical Development of Quantum Theory is a definitive historical study of that scientific work and the human struggles that accompanied it from the beginning. Drawing upon such materials as the resources of the Archives for the History of Quantum Physics, the Niels Bohr Archives, and the archives and scientific correspondence of the principal quantum physicists, as well as Jagdish Mehra's personal discussions over many years with most of the architects of quantum theory, the authors have written a rigorous scientific history of quantum theory in a deeply human context. This multivolume work presents a rich account of an intellectual triumph: a unique analysis of the creative scientific process. The Historical Development of Quantum Theory is science, history, and biography, all wrapped in the story of a great human enterprise. Its lessons will be an aid to those working in the sciences and humanities alike.

Barry Simon's book both summarizes and introduces the remarkable progress in constructive quantum field theory that can be attributed directly to the exploitation of Euclidean methods. During the past two years deep relations on both the physical level and on the level of the mathematical structure have been either uncovered or made rigorous. Connections between quantum fields and the statistical mechanics of ferromagnets have been established, for example, that now allow one to prove numerous inequalities in quantum field theory. In the first part of the book, the author presents the Euclidean methods on an axiomatic level and on the constructive level where the traditional results of the P(O)2 theory are translated into the new language. In the second part Professor Simon gives one of the approaches for constructing models of non-trivial, two-dimensional Wightman fields--specifically, the method of correlation inequalities. He discusses other approaches briefly. Drawn primarily from the author's lectures at the Eidenossiehe Technische Hochschule, Zurich, in 1973, the volume will appeal to physicists and mathematicians alike; it is especially suitable for those with limited familiarity with the literature of this very active field. Originally published in 1974. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This volume, available for the first time in paperback, is a standard work on the physical aspects of acoustics. Starting from first principles, the authors have successfully produced a unified and thorough treatment of the subjects of generation, propagation, absorption, reflection, and scattering of compressional waves in fluids, progressing to such topics as moving sound sources, turbulence, and wave-induced vibration of structures. Material is included on viscous and thermal effects, on the acoustics of moving media, on plasma acoustics, on nonlinear effects, and on the interaction between light and sound. Problems, with answers in many cases, are given at the end of each chapter. They contain extensions to further applications, thus enhancing the reference value of the book. Many of the examples worked out in the text and in the problem solutions were not previously published. Anyone familiar with calculus and vector analysis should be able to understand the mathematical techniques used here.

This book addresses the modelling of mechanical waves by asking the right questions about them and trying to find suitable answers. The questions follow the analytical sequence from elementary understandings to complicated cases, following a step-by-step path towards increased knowledge. The focus is on waves in elastic solids, although some examples also concern non-conservative cases for the sake of completeness. Special attention is paid to the understanding of the influence of microstructure, nonlinearity and internal variables in continua. With the help of many mathematical models for describing waves, physical phenomena concerning wave dispersion, nonlinear effects, emergence of solitary waves, scales and hierarchies of waves as well as the governing physical parameters are analysed. Also, the energy balance in waves and non-conservative models with energy influx are discussed. Finally, all answers are interwoven into the canvas of complexity.

Dieser Bericht behandelt die akustischen Aspekte der sprachlichen Kommunikation, insbesondere wenn sie durch Gerausche, Nachhall oder Schwerhorigkeit gestort ist. Produktion und Wahrnehmung von Sprache, also Sprechen und Horen, dienen wesentlich der Integration eines Menschen in das soziale und kulturelle Leben. Beides ist die Voraussetzung fur ein kompetentes Verhalten in der Familie, in der Offentlichkeit, am Arbeitsplatz und in der Ausbildung. Der Fortschritt der Technik verlangt notwendig nach mehr Kommunikation: u.a. aufgrund veranderter Betriebsablaufe (Teamarbeit zur Verbindung von Entwicklung, Konstruktion, Produktion, Verteilung der Arbeit an unterschiedlichen Standorten), an mobilen Arbeitsplatzen, bei der Benutzung akustischer Medien oder mobiler Telefone und beim weltweiten Kommunizieren in einer Zweitsprache. Die Auswirkungen reduzierter Kommunikation aufgrund von Larm oder Schwerhorigkeit sind deshalb betrachtlich. Durch akustisch schlecht gestaltete Raume, Arbeitsplatze und Kommunikationsgerate und durch zu hohe Sprechpegel, z.B. aus Lautsprechern, wird die Sprachkommunikation zusatzlich eingeschrankt. Damit ist nicht nur Wahrnehmen und Verstehen von Sprache reduziert, sondern zwingend auch der Informationsaustausch: die private, soziale und betriebliche Interaktion. Zu beachten sind ebenso auch langfristige Folgen, wie z.B. ein verzogerter Spracherwerb in Kindergarten und Schule, die Abnahme der Qualitat der Arbeit, die Zunahme von Konflikten und von Unfallen am Arbeitsplatz und eine Verminderung der physischen und psychischen Gesundheit. Ausgangspunkt der Analyse ist das Sprecher-Horer-Modell im Kontext der Psychoakustik. Einleitend werden wichtige Grundlagen des Sprechens, der Sprache, der Wahrnehmung und des Verstehens von Sprache dargestellt: der Sprecher produziert Sprache (Sprechweise, Artikulation), die zum Horer im Raum oder uber elektroakustische Anlagen ubertragen wird und gestort werden kann (Bandbegrenzung, Gerausche, Nachhall, Ubersteuerung etc.). Der Horer muss die Sprache wahrnehmen und verstehen, auch wenn er schwerhorig ist oder Gehorschutz tragt. Die Messung der Sprachverstandlichkeit wird anhand der Sprachindices erlautert. Die Methoden zur Bestimmung der Qualitat der Sprachkommunikation werden aufbauend auf der Verstandlichkeit durch Parameter wie Konzentration und Belastigung erganzt und neu formuliert. Die so entwickelten Qualitatsstufen werden ausfuhrlich diskutiert, dazu werden Kriterien fur die Raumgestaltung (u.a. Schulen) abgeleitet. Die Analyse soll es ermoglichen, den Umgebungsbereich fur sprachliche Kommunikation "barrierefrei" zu gestalten, so dass die Kommunikationspartner ungeachtet ihres Alters, individueller Handicaps (begrenzte Sprachkompetenz, Schwerhorigkeit) in offentlichen Bereichen und in der Arbeitswelt als gleichberechtigte Partner am Gesprach teilnehmen konnen. Ziel dieses Buches ist es auch uber die Akustik hinaus einen grossen Leserkreis unterschiedlicher Interessen und Berufsgruppen wie Ergonomen, Psychologen, Mediziner, Architekten, Medienexperten in die Diskussion uber die Sprachkommunikation aus wissenschaftlicher und angewandter Sicht einzufuhren und Hinweise fur eine optimale Gestaltung zu geben."

The 34 chapters of the 2nd edition of How to Gain Gain give a detailed insight into a collection (54) of the most common gain producing, constant current generating possibilities, and electronic noise creation of triodes for audio pre-amplifier purposes. These chapters also offer complete sets of formulae to calculate gain, frequency and phase responses, and signal-to-noise ratios of certain building blocks built-up with this type of vacuum valve (tube). In all cases detailed derivations of the gain formulae are also presented. All what is needed are the data sheet valve characteristic figures of the triode's mutual conductance, the gain factor and the internal plate (anode) resistance. To calculate frequency and phase responses of gain stages the different data sheet based input and output capacitances have to be taken into account too. To calculate transfer functions and signal-to-noise ratios for any kind of triode driven gain stage, including all its bias setting, frequency, phase, and electronic noise influencing components, example Mathcad 11 worksheets as an essential simulation tool for each chapter allow easy follow-up and application of the respective formulae. Free download of all worksheets is guaranteed from the editor's web-site.

Keywords: high-temperature oxidation; hot corrosion; corrosion in acids, alkalis and molten salts; effects of corrosion on the physico-mechanical properties of ceramics; stress corrosion; corrosion protection; development of oxidation-resistant ceramics; role of purity, donations and microstructure.

"Principles of Statistical Radiophysics" is a four-volume series that introduces the newcomer to the theory of random functions. It aims at providing the background necessary to understand papers and monographs on the subject and to carry out independant research in fields where fluctuations are of importance, e.g. radiophysics, optics, astronomy, and acoustics. Volume 2, "Correlation Theory of Random Processes," presents the correlation theory of nonstationary processes paying particular attention to periodically nonstationary processes. Physical phenomena like interference, coherence and polarisation of random oscillations, thermal noise in discrete dynamical systems, and the spectral representations of random actions on discrete systems are dealt with.

Suitable for both individual and group learning, Engineering Acoustics focuses on basic concepts and methods to make our environments quieter, both in buildings and in the open air.

The author s tutorial style derives from the conviction that understanding is enhanced when the necessity behind the particular teaching approach is made clear. He also combines mathematical derivations and formulas with extensive explanations and examples to deepen comprehension.

Noise is everywhere and in most applications that are related to audio and speech, such as human-machine interfaces, hands-free communications, voice over IP (VoIP), hearing aids, teleconferencing/telepresence/telecollaboration systems, and so many others, the signal of interest (usually speech) that is picked up by a microphone is generally contaminated by noise. As a result, the microphone signal has to be cleaned up with digital signal processing tools before it is stored, analyzed, transmitted, or played out. This cleaning process is often called noise reduction and this topic has attracted a considerable amount of research and engineering attention for several decades. One of the objectives of this book is to present in a common framework an overview of the state of the art of noise reduction algorithms in the single-channel (one microphone) case. The focus is on the most useful approaches, i.e., filtering techniques (in different domains) and spectral enhancement methods. The other objective of Noise Reduction in Speech Processing is to derive all these well-known techniques in a rigorous way and prove many fundamental and intuitive results often taken for granted. This book is especially written for graduate students and research engineers who work on noise reduction for speech and audio applications and want to understand the subtle mechanisms behind each approach. Many new and interesting concepts are presented in this text that we hope the readers will find useful and inspiring.

Hydrodynamic equations well describe averaged parameters of turbulent steady flows, at least in pipes where boundary conditions can be estimated. The equations might outline the parameters fluctuations as well, if entry conditions at current boundaries were known. This raises, in addition, the more comprehensive problem of the primary perturbation nature, noted by H.A. Lorentz, which still remains unsolved. Generally, any flow steadiness should be supported by pressure waves emitted by some external source, e.g. a piston or a receiver. The wave plane front in channels quickly takes convex configuration owing to Rayleigh's law of diffraction divergence. The Schlieren technique and pressure wave registration were employed to investigate the wave interaction with boundary layer, while reflecting from the channel wall. The reflection induces boundary-layer local separation and following pressure rapid increase within the perturbation zone. It propagates as an acoustic wave packet of spherical shape, bearing oscillations of hydrodynamic parameters. Superposition of such packets forms a spatio-temporal field of oscillations fading as 1/r. This implies a mechanism of the turbulence. Vorticity existing in the boundary layer does not penetrate in itself into potential main stream. But the wave leaving the boundary layer carries away some part of fluid along with frozen-in vorticity. The vorticity eddies form another field of oscillations fading as 1/r2. This implies a second mechanism of turbulence. Thereupon the oscillation spatio-temporal field and its randomization development are easy computed. Also, normal burning transition into detonation is explained, and the turbulence inverse problem is set and solved as applied to plasma channels created by laser Besselian beams.

AN AUTHORITATIIVE, UP-TO-DATE INTRODUCTION TO PHYSICAL ACOUSTICS

Easy to read and understand, Fundamentals of Physical Acoustics fills a long-standing need for an acoustics text that challenges but does not overpower graduate students in engineering and physics. Mathematical results and physical explanations go hand in hand, and a unique feature of the book is the balance it strikes between time-domain and frequency-domain presentations.

Fundamentals of Physical Acoustics is intended for a two-semester, first-year graduate course, but is also suitable for advanced undergraduates. Emphasis on plane waves in the first part of the book keeps the mathematics simple yet accommodates a broad range of topics: propagation, reflection and transmission, normal modes and simple waveguides for rectilinear geometries, horns, inhomogeneous media, and sound absorption and dispersion.

The second part of the book is devoted to a more rigorous development of the wave equation, spherical and cylindrical waves (including the more advanced mathematics required), advanced waveguides, baffled piston radiation, diffraction (treated in the time domain), and arrays. Applications and examples are drawn from:

• Atmospheric acoustics
• Noise control
• Underwater acoustics
• Engineering acoustics
• Acoustical measurements

Supplemented with more than 300 graphs and figures as well as copious end-of-chapter problems, Fundamentals of Physical Acoustics is also an excellent professional reference for engineers and scientists.

Mit dem Buch der Klange fuhrt uns der britische Wissenschaftler Trevor Cox in verborgene Hoerwelten. Es weckt in uns das Verlangen, in einem Alltag, in dem das Visuelle so sehr dominiert, doch einmal genauer hinzuhoeren - und unsere Ohren fur das wunderbare Klangdurcheinander um uns herum zu oeffnen. Als Fachmann fur technische Akustik hat sich Trevor Cox lange damit beschaftigt, unerwunschte Gerausche verschwinden zu lassen, ob Echos in Konzertsalen oder Larm in Klassenzimmern. Eines Tages aber verschaffte ihm ein Ausflug in die Londoner Kanalisation ein erstaunliches Hoererlebnis - und die Erkenntnis: Statt seltsame Gerausche abzustellen, sollten wir die seltsamsten und bizarrsten akustischen Effekte zu schatzen lernen: als die Klangwunder unserer Erde. Das Buch der Klange beschreibt seine Suche nach diesen Klangwundern. In der Mojave-Wuste besucht Cox singende Dunen. In Frankreich entdeckt er ein Echo, das zu Scherzen aufgelegt ist. In Kalifornien fahrt er eine "singende" Strasse entlang, die die Ouverture zu Wilhelm Tell erklingen lasst (wenn auch ziemlich schief). Und eine Entdeckung ist so beeindruckend, dass sie einen Eintrag ins Guinness-Buch der Rekorde verdient hat.

Trees can reduce noise by sound reflection and absorption and this is the first book bringing together the widely scattered literature on noise abatement by urban trees. The book will interest those concerned with environmental management, noise control, and urban forestry. It is an invaluable source of information for environmental managers, foresters, acousticians, engineers, architects, scientists, and students.

The book provides an accessible overview of audio signal processing, and enables readers to design and write algorithms for the analysis, synthesis, and manipulation of musical and acoustic signals for any programming language. It provides an overview of highly interdisciplinary topics developed in a simple but rigorous way, and described in a unified and formal language which focuses on determining discrete-time audio signal models. Readers can find within a self-contained volume basic topics ranging over different disciplines: mechanical acoustics, physical systems and linear and nonlinear models, with lumped and distributed parameters; described and developed with the same level of mathematical formalism, easy to understand and oriented to the development of algorithms. Topics include the fundamental concepts of acoustic mechanics and vibration; the design of filters and equalizers for sound signals, the so-called audio effects, abstract methods of sound synthesis, and finally, methods of synthesis by physical modeling.
