Book Description
Physical Acoustics: Principles and Methods reviews the principles and methods of physical acoustics and covers topics ranging from third sound in superfluid helium films to the method of matched asymptotic expansions (MAE). Ultrasonic diffraction from single apertures and its application to pulse measurements and crystal physics are also discussed, together with elastic surface wave devices, acoustic emission, and nonlinear effects in piezoelectric quartz crystals. Comprised of six chapters, this volume begins with a detailed treatment of the theory of third sound in superfluid helium films, third sound resonators, and many other properties. The second chapter is devoted to the MAE method, with emphasis on its ability to produce results in acoustics and to provide insight into classical problems. Subsequent chapters deal with bulk and surface waves; phase coded signals and their generation and detection by interdigital grid structures; elastic surface wave devices such as pulse compression filters; and nonlinear effects in quartz crystals. The final chapter describes acoustic emission and the noise produced in materials when they are strained. This book will be of interest to physicists.

Book Description
Physical Acoustics: Principles and Methods, Volume VIII discusses a number of themes on physical acoustics that are divided into seven chapters. Chapter 1 describes the principles and applications of a tool for investigating phonons in dielectric crystals, the spin phonon spectrometer. The next chapter discusses the use of ultrasound in investigating Landau quantum oscillations in the presence of a magnetic field and their relation to the strain dependence of the Fermi surface of metals. The third chapter focuses on the ultrasonic measurements that are made by pulsing methods with velocities obtained through phase comparison methods and attenuations obtained through comparing pulse heights for successive reflections. In Chapter 4, methods for measuring the properties of solids and liquids at very high pressures are described. Chapter 5 explores some of the relationships between the thermal equilibrium properties of solids and mechanical properties such as the second- and third-order elastic constants. The sixth chapter discusses the interaction of sound waves with thermal phonons in dielectric crystals and emphasizes the relationship between the various theories proposed and the effect of phonon interactions on the velocity of sound. The last chapter describes the applications to metals and rock mechanics of internal friction at low frequencies due to dislocations. This book is beneficial to students and physicists conducting work on physical acoustics.

Book Description
Physical Acoustics: Principles and Methods, Volume II, Part B: Properties of Polymers and Nonlinear Acoustics presents the applications of the methods for detecting and generating sound waves. This book deals with more closely packed materials than found in liquid, which retain the ability to perform some atomic movements. Comprised of six chapters, this volume starts with an overview of the significant method for measuring nonlinearities in liquids and solids in the light diffraction method. This text then describes the basic generalization of linear viscoelastic theory, which is the only theory with enough power, range, and simplicity to be of use in relating the mechanical properties as a whole. Other chapters consider the phenomena that are observed during time-dependent dilatation of amorphous polymers and discuss the relationship of this behavior to that observed during shearing deformation. The final chapter deals with the distortion of the ultrasonic waveform arising from nonlinearity. Physicists and researchers will find this book useful.

Book Description
Physical Acoustics: Principles and Methods, Volume l—Part A focuses on high frequency sound waves in gases, liquids, and solids that have been proven as powerful tools in analyzing the molecular, defect, domain wall, and other types of motions. The selection first tackles wave propagation in fluids and normal solids and guided wave propagation in elongated cylinders and plates. Discussions focus on fundamentals of continuum mechanics; small-amplitude waves in a linear viscoelastic medium; representation of oscillations and waves; and special effects associated with guided elastic waves in plates and cylinders. The book also touches on piezoelectric and piezomagnetic materials and their functions in transducers, including polycrystalline ferroelectrics, equations of the piezoelectric medium, and equivalent circuits. The publication takes a look at ultrasonic methods for measuring the mechanical properties of liquids and solids and the use of piezoelectric crystals and mechanical resonators in filters and oscillators. The text then ponders on guided wave ultrasonic delay lines and multiple reflection ultrasonic delay lines, as well as transmission of sound waves in solids, torsional mode delay lines, and transducer considerations. The selection is a valuable reference for readers interested in physical acoustics.

Book Description
Physical Acoustics: Principles and Methods, Volume XIV is a five-chapter text that covers significant studies on acoustic microscopy, sound propagation in liquid crystals, ultrasonic transducers, and ultrasonic flowmeters. The opening chapter discusses techniques of acoustic microscopy, aberration and resolution performance, acoustic lens transfer functions, antireflection coatings, and both transmission and reflection acoustic microscopy. The following chapter deals with the applications to the states called liquid crystals or anisotropic liquids, states in which the material flows but yet has a long-range order that makes it macroscopically anisotropic. The third chapter focuses on the principles and practical applications of electromagnetic transducers for both surface waves and bulk waves. The fourth chapter surveys first the characterization of ultrasonic transducers for materials testing and then compares actual responses to those of an ""ideal"" transducer, elaborating on the many important factors that affect the results obtained with an ultrasonic testing system. The final chapter explains the principles underlying ultrasonic measurements of flow, specifically covering eight different categories of ultrasonic flow measurement principles and their industrial applications indicated. This book will be of great value to researchers in their fields of electronics technology and applied and engineering mechanics.

Book Description
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.
