Written by the world's leading scholars and researchers in the
emerging field of sound studies, The Oxford Handbook of Sound
Studies offers new and fully engaging perspectives on the
significance of sound in its material and cultural forms. The book
considers sounds and music as experienced in such diverse settings
as shop floors, laboratories, clinics, design studios, homes, and
clubs, across an impressively broad range of historical periods and
national and cultural contexts.
Science has traditionally been understood as a visual matter, a
study which has historically been undertaken with optical
technologies such as slides, graphs, and telescopes. This book
questions that notion powerfully by showing how listening has
contributed to scientific practice. Sounds have always been a part
of human experience, shaping and transforming the world in which we
live in ways that often go unnoticed. Sounds and music, the authors
argue, are embedded in the fabric of everyday life, art, commerce,
and politics in ways which impact our perception of the world.
Through an extraordinarily diverse set of case studies, authors
illustrate how sounds -- from the sounds of industrialization, to
the sounds of automobiles, to sounds in underwater music and
hip-hop, to the sounds of nanotechnology -- give rise to new forms
listening practices. In addition, the book discusses the rise of
new public problems such as noise pollution, hearing loss, and the
"end" of the amateur musician that stem from the spread and
appropriation of new sound- and music-related technologies, analog
and digital, in many domains of life.
Rich in vivid and detailed examples and compelling case studies,
and featuring a companion website of listening samples, this
remarkable volume boldly challenges readers to rethink the way they
hear and understand the world.
Foundations of Engineering Acoustics takes the reader on a journey
from a qualitative introduction to the physical nature of sound,
explained in terms of common experience, to mathematical models and
analytical results which underlie the techniques applied by the
engineering industry to improve the acoustic performance of their
products. The book is distinguished by extensive descriptions and
explanations of audio-frequency acoustic phenomena and their
relevance to engineering, supported by a wealth of diagrams, and by
a guide for teachers of tried and tested class demonstrations and
laboratory-based experiments.
Foundations of Engineering Acoustics is a textbook suitable for
both senior undergraduate and postgraduate courses in mechanical,
aerospace, marine, and possibly electrical and civil engineering
schools at universities. It will be a valuable reference for
academic teachers and researchers and will also assist Industrial
Acoustic Group staff and Consultants.
Comprehensive and up-to-date: broad coverage, many illustrations,
questions, elaborated answers, references and a bibliography
Introductory chapter on the importance of sound in technology and
the role of the engineering acoustician
Deals with the fundamental concepts, principles, theories and forms
of mathematical representation, rather than methodology
Frequent reference to practical applications and contemporary
technology
Emphasizes qualitative, physical introductions to each principal as
an entree to mathematical analysis for the less theoretically
oriented readers and courses
Provides a 'cook book' of demonstrations and laboratory-based
experiments for teachers
Useful for discussing acoustical problems with non-expert
clients/managers because the descriptive sections are couched in
largely non-technical language and any jargon is explained
Draws on the vast pedagogic experience of the writer"
Intended a both a textbook and a reference, Fourier Acoustics
develops the theory of sound radiation uniquely from the viewpoint
of Fourier Analysis. This powerful perspective of sound radiation
provides the reader with a comprehensive and practical
understanding which will enable him or her to diagnose and solve
sound and vibration problems in the 21st Century. As a result of
this perspective, Fourier Acoustics is able to present thoroughly
and simply, for the first time in book form, the theory of
nearfield acoustical holography, an important technique which has
revolutionised the measurement of sound. Relying little on material
outside the book, Fourier Acoustics will be invaluable as a
graduate level text as well as a reference for researchers in
academia and industry.

"This volume deals with the interaction of acoustic fields with
bubbles in liquids, with emphasis on the principles of
cavitation--the generation of bubbles in liquids by rapid changes,
such as those introduced by ultrasound. When cavity bubbles implode
they produce shock waves in the liquid. If cavitation is induced by
turbulent flow, components can be damaged. These phenomena have
important implications, particularly in underwater acoustics, one
of the fastest growing fields in acoustics research. The Acoustic
Bubble skillfully explains the physical processes involved in
cavitation both by analogy and formulation, making the concepts
accessible to those with a minimal background in mathematics. This
book willbe of great interest to those engaged in research in a
wide range of areas, from sonochemistry to the sensitization of
explosives.
This book describes modern techniques for reducing the level of
airborne noise through the introduction of sound radiated by
additional secondary sources, bringing together the results of
contemporary research in this area. It is the combination of the
physical properties of sound fields and modern digital signal
processing technology that has made the active control of sound a
practical proposition in a number of important applications. The
book covers both these aspects of the subject, initially at a
fundamental level, and then in detail in later chapters. The
structure of the book is such that it should be suitable for both
those seeking a basic understanding of the subject and as a
reference for researchers in the field. One of the key features of
the work is thus the unified presentation of material from the two
disciplines of acoustics and signal processing.
Acoustics: Sound Fields, Transducers and Vibration, Second Edition
guides readers through the basics of sound fields, the laws
governing sound generation, radiation, and propagation, and general
terminology. Specific sections cover microphones (electromagnetic,
electrostatic, and ribbon), earphones, and horns, loudspeaker
enclosures, baffles and transmission lines, miniature applications
(e.g. MEMS microphones and micro speakers in tablets and smart
phones), sound in enclosures of all sizes, such as school rooms,
offices, auditoriums and living rooms, and fluid-structure
interaction. Numerical examples and summary charts are given
throughout the text to make the material easily applicable to
practical design. New to this edition: A chapter on electrostatic
loudspeakers A chapter on vibrating surfaces (membranes, plates,
and shells) Readers will find this to be a valuable resource for
experimenters, acoustical consultants, and to those who anticipate
being engineering designers of audio equipment. It will serve as
both a text for students in engineering departments and as a
valuable reference for practicing engineers.
Optical properties, particularly in the infrared range of
wavelengths, continue to be of enormous interest to both material
scientists and device engineers. The need for the development of
standards for data of optical properties in the infrared range of
wavelengths is very timely considering the on-going transition of
nano-technology from fundamental R&D to manufacturing.
Radiative properties play a critical role in the processing,
process control and manufacturing of semiconductor materials,
devices, circuits and systems. The design and implementation of
real-time process control methods in manufacturing requires the
knowledge of the radiative properties of materials. Sensors and
imagers operate on the basis of the radiative properties of
materials. This book reviews the optical properties of various
semiconductors in the infrared range of wavelengths. Theoretical
and experimental studies of the radiative properties of
semiconductors are presented. Previous studies, potential
applications and future developments are outlined. In Chapter 1, an
introduction to the radiative properties is presented. Examples of
instrumentation for measurements of the radiative properties is
described in Chapter 2. In Chapters 3-11, case studies of the
radiative properties of several semiconductors are elucidated. The
modeling and applications of these properties are explained in
Chapters 12 and 13, respectively. In Chapter 14, examples of the
global infrastructure for these measurements are illustrated.
Like rocket science or brain surgery, quantum mechanics is
pigeonholed as a daunting and inaccessible topic, which is best
left to an elite or peculiar few. This classification was not
earned without some degree of merit. Depending on perspective;
quantum mechanics is a discipline or philosophy, a convention or
conundrum, an answer or question. Authors have run the gamut from
hand waving to heavy handed in hopes to dispel the common beliefs
about quantum mechanics, but perhaps they continue to promulgate
the stigma. The focus of this particular effort is to give the
reader an introduction, if not at least an appreciation, of the
role that linear algebra techniques play in the practical
application of quantum mechanical methods. It interlaces aspects of
the classical and quantum picture, including a number of both
worked and parallel applications. Students with no prior experience
in quantum mechanics, motivated graduate students, or researchers
in other areas attempting to gain some introduction to quantum
theory will find particular interest in this book.
Electromagnetic homogenization is the process of estimating the
effective electromagnetic properties of composite materials in the
long-wavelength regime, wherein the length scales of
nonhomogeneities are much smaller than the wavelengths involved.
This is a bird's-eye view of currently available homogenization
formalisms for particulate composite materials. It presents
analytical methods only, with focus on the general settings of
anisotropy and bianisotropy. The authors largely concentrate on
'effective' materials as opposed to 'equivalent' materials, and
emphasize the fundamental (but sometimes overlooked) differences
between these two categories of homogenized composite materials.
The properties of an 'effective' material represents those of its
composite material, regardless of the geometry and dimensions of
the bulk materials and regardless of the orientations and
polarization states of the illuminating electromagnetic fields. In
contrast, the properties of 'equivalent' materials only represent
those of their corresponding composite materials under certain
restrictive circumstances.
This book reviews basic electromagnetic (EM) wave theory and
applies it specifically to lasers in order to give the reader not
only tangible examples of how the theory is manifested in real
life, but also practical knowledge about lasers, and their
operation and usage. The latter can be useful for those involved
with using lasers. As a short treatise on this subject matter, this
book is not intended to dwell deeply into the details of EM waves
nor lasers. A bibliography is provided for those who wish to
explore in more depth the topics covered in this book. Rather the
aim of this book is to offer a quick overview, which will allow the
reader to gain a competent general understanding of EM waves and
lasers.
This book addresses the nature of sound, focusing on the
characteristics of sound waves in the context of time structures.
This time domain approach provides an informative and intuitively
understandable description of various acoustic topics such as sound
waves travelling in an acoustic tube or in other media where
spectral or modal analysis can be intensively performed. Starting
from the introductory topic of sinusoidal waves, it discusses the
formal relationship between the time and frequency domains,
summarizing the fundamental notions of Fourier or z-transformations
and linear systems theory, along with interesting examples from
acoustical research. The books novel approach is of interest to
research engineers and scientists In particular, the expressions
concerning waveforms including the impulse responses are important
for audio engineers who are familiar with digital signal analysis.
Every chapter includes simple exercises designed to be solved
without the need for a computer. Thus they help reconfirm the
fundamental ideas and notions present in every chapter. The book is
self-contained and concise, and requires only basic knowledge of
acoustics and signal processing, making it valuable as a textbook
for graduate and undergraduate university courses.
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.
