Описание: Senior level/graduate level text/reference presenting state-of-the- art numerical techniques to solve the wave equation in heterogeneous fluid-solid media. Numerical models have become standard research tools in acoustic laboratories, and thus computational acoustics is becoming an increasingly important branch of ocean acoustic science. The first edition of this successful book, written by the recognized leaders of the field, was the first to present a comprehensive and modern introduction to computational ocean acoustics accessible to students. This revision, with 100 additional pages, completely updates the material in the first edition and includes new models based on current research. It includes problems and solutions in every chapter, making the book more useful in teaching (the first edition had a separate solutions manual). The book is intended for graduate and advanced undergraduate students of acoustics, geology and geophysics, applied mathematics, ocean engineering or as a reference in computational methods courses, as well as professionals in these fields, particularly those working in government (especially Navy) and industry labs engaged in the development or use of propagating models.

Описание: This Unique Volume Presents An Original Approach To Physical Acoustics With Additional Emphasis On The Most Useful Surface Acoustic Waves On Solids. The Study Is Based On Foundational Work Of L?on Brillouin, And Application Of The Celebrated Invariance Theorem Of Emmy Noether To An Element Of Volume That Is Representative Of The Wave Motion. This Approach Provides An Easy Interpretation Of Typical Wave Motions Of Physical Acoustics In Bulk, At Surfaces, And Across Interfaces, In The Form Of The Motion Of Associated Quasi-Particles. This Type Of Motion, Newtonian Or Not, Depends On The Wave Motion Considered, And On The Original Modeling Of The Continuum That Supports It. After A Thoughtful Review Of Brillouin'S Fundamental Ideas Related To Radiative Stresses, Wave Momentum And Action, And The Necessary Reminder On Modern Nonlinear Continuum Thermomechanics, Invariance Theory And Techniques Of Asymptotics, A Variety Of Situations And Models Illustrates The Power And Richness Of The Approach And Its Strong Potential In Applications. Elasticity, Piezoelectricity And New Models Of Continua With Nonlinearity, Viscosity And Some Generalized Features (Microstructure, Weak Of Strong Nonlocality) Or Unusual Situations (Bounding Surface With Energy, Elastic Thin Film Glued On A Surface Waveguide), Are Considered, Exhibiting Thus The Versatility Of The Approach. This Original Book Offers On Innovative Vision And Treatment Of The Problems Of Wave Propagation In Deformable Solids. It Opens Up New Horizons In The Theoretical And Applied Facets Of Physical Acoustics.

Описание: Noise from cars, trains, and aeroplanes can be heard at large distances from the source. Accurate predictions of the loudness of the noise require accurate computations of sound propagation in the atmosphere. This book describes models that can be used for these computations. The models take into account complex effects of the atmosphere and the ground surface on sound waves, including the effects of wind and temperature distributions, atmospheric turbulence, irregular terrain, and noise barriers. The main text of the book focuses on physical effects in atmospheric acoustics. The effects are illustrated by many numerical examples. The main text requires a very limited mathematical background from the reader; detailed mathematical descriptions of the models, developed from the basic principles of acoustics, are presented in appendices. Models for moving media are compared with models that are based on the effective sound speed approach. Both two-dimensional models and three-dimensional models are presented. As meteorological effects play an important role in atmospheric acoustics, selected topics from boundary layer meteorology and the theory of turbulence are also presented.
Описание: A study of the mathematical analysis - modelling physical concepts, existence, uniqueness, stability, asymptotics, computational schemes, and so on - involved
in predicting complex mechanical/acoustical behaviour/response and identifying or optimizing mechanical/acoustical systems giving rise to phenomena that are either observed or
aimed at. The forward problems consist in solving generally coupled, nonlinear systems of integral or partial (integer or fractional) differential equations with nonconstant coefficients. The
identification/optimization of the latter, of the driving terms and/or of the boundary conditions, all of which are often affected by random perturbations, forms the class of related inverse
or control problems.

Описание: Inverse problems have a long history in acoustics, optics, electromagnetics and geophysics, but only recently have the signals provided by ocean acoustic sensors become numerous and sophisticated enough to allow for realistic identification of the ocean parameters. Acoustic signals propagating for long distances in the water column and reflections of underwater sound from the ocean boundaries provide novel problems of interpretation and inversion. The chapters in this volume discuss some of the contemporary aspects of these problems. They provide recent and useful results for bottom recognition, inverse scattering in acoustic wave guides, and ocean acoustic tomography, as well as a discussion of some of the new algorithms, such as those related to matched-field processing, that have recently been used for inverting experimental data. Each chapter is by a noted expert in the field and represents the state of the art. The chapters have all been edited to provide a uniform format and level of presentation.
Описание: Blind Signal Separation (BSS) deals with recovering (filtered versions of) source signals from an observed mixture thereof. The term `blind' relates to the fact that there are no reference signals for the source signals and also that the mixing system is unknown. This book presents a new method for blind signal separation, which is developed to work on microphone signals. Acoustic Echo Cancellation (AEC) is a well-known technique to suppress the echo that a microphone picks up from a loudspeaker in the same room. Such acoustic feedback occurs for example in hands-free telephony and can lead to a perceived loud tone. For an application such as a voice-controlled television, a stereo AEC is required to suppress the contribution of the stereo loudspeaker setup. A generalized AEC is presented that is suited for multi-channel operation. New algorithms for Blind Signal Separation and multi-channel Acoustic Echo Cancellation are presented. A background is given in array signal processing methods, adaptive filter theory, and fast filtering in the frequency domain. The included CD-ROM can be played using any compact disc player to play the simulation results that are described in the text. When inserted into a computer, it furthermore gives Matlab implementations of the new algorithms along with audio data with which to experiment. This makes the book suited to researchers, engineers, and university students, who want to get acquainted with these emerging fields.

Описание: Noise pollution around airports, trains, and industries increasingly attracts environmental concern and regulation. Designers and researchers have intensified the use of large-eddy simulation (LES) for noise reduced industrial design and acoustical research. This book, written by 30 experts, presents the theoretical background of acoustics and of LES, followed by details about numerical methods, e.g. discretization schemes, boundary conditions, coupling aspects. Industrially relevant, hybrid RANS/LES techniques for acoustic source predictions are presented in detail. Many applications are featured ranging from simple geometries for mixing layers and jet flows to complex wing and car geometries. Selected applications include recent scientific investigations at industrial and university research institutions. Presently one can't offer perfect solution methodologies that address all relevant applications, however the book presents a state of the art collection of methods, tools and evaluation methodologies. The advantages and weaknesses of both the commercial and the research methodologies are carefully presented.
