Book Synopsis Theoretical Acoustics by : Philip McCord Morse
Download or read book Theoretical Acoustics written by Philip McCord Morse and published by Princeton University Press. This book was released on 1986 with total page 954 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Hearing written by Aage R. Moller and published by Academic Press. This book was released on 2000-05-25 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a new trend in the education of audiologists that emphasizes the basics of hearing--Hearing: Its Physiology and Pathophysiology addresses this trend. It covers not only the basics of hearing but also the basics of pathophysiology, which is not covered in a comprehensive way in any other text today. This book recognizes the fact that the diseased auditory system does indeed function, but in a different way than the normal system. Few books have addressed the pathophysiology of the ear and the auditory nervous system. Most books on hearing begin with a detailed description of the physics of sound, which scares many readers away because they believe they need to understand acoustics to understand how the ear functions. Hearing: Its Physiology and Pathophysiology does not assume that the readers are physicists, which would be analogous to assuming that visual physiologists would need to know quantum mechanics to understand how the visual nervous system functions. * This book provides a thorough understanding of the anatomy and function of the auditory system * To the basic scientist, it will provide an understanding of the auditory system and how it works * To the clinician, it will provide insight into the normal and diseased auditory system

Book Synopsis Propagation of Sound in Porous Media by : J.F. Allard
Download or read book Propagation of Sound in Porous Media written by J.F. Allard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has grown out of the research activities of the author in the fields of sound propagation in porous media and modelling of acoustic materials. It is assumed that the reader has a background of advanced calculus, including an introduction to differential equations, complex variables and matrix algebra. A prior exposure to theory of elasticity would be advantageous. Chapters 1-3 deal with sound propagation of plane waves in solids and fluids, and the topics of acoustic impedance and reflection coefficient are given a large emphasis. The topic of flow resistivity is presented in Chapter 2. Chapter 4 deals with sound propagation in porous materials having cylindrical pores. The topics of effective density, and of tortuosity, are presented. The thermal exchanges between the frame and the fluid, and the behaviour of the bulk modulus of the fluid, are described in this simple context. Chapter 5 is concerned with sound propagation in other porous materials, and the recent notions of characteristic dimensions, which describe thermal exchanges and the viscous forces at high frequencies, are introduced. In Chapter 6, the case of porous media having an elastic frame is considered in the context of Biot theory, where new topics described in Chapter 5 have been included.

Book Synopsis Physical Acoustics and Metrology of Fluids by : Martin Trusler
Download or read book Physical Acoustics and Metrology of Fluids written by Martin Trusler and published by CRC Press. This book was released on 2020-11-25 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of sound waves with the medium through which they pass can be used to investigate the thermophysical properties of that medium. With the advent of modern instrumentation, it is now possible to determine the speed and absorption of sound with extremely high precision and, through the dependence of those quantities on variables like temperature, pressure, and frequency to gain a sensitive measure of one or more properties of fluid. This has led to renewed interest in such measurements and in the extraction of thermophysical properties of gases and liquids there from. Physical Acoustics and Metrology of Fluids describes both how to design experiments to achieve the highest possible accuracy and how to relate the quantities measured in those experiments to the thermophysical properties of the medium. A thorough theoretical examination of the alternative experimental methods available is designed to guide the experimentalist toward better and more accurate methods. This theoretical analysis is enhanced and complemented by an in-depth discussion of practical experimental techniques and the problems inherent within them. Bringing together the fields of thermodynamics, kinetic theory, fluid mechanics, and theoretical acoustics, plus a wealth of information about practical instruments, this book represents an essential reference on the design and execution of valuable experiments in fluid metrology and physical acoustics.
