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.
Acoustic microscopy enables the elastic properties of materials to
be imaged and measured with the resolution of a good microscope. By
using frequencies in the microwave regime, it is possible to make
the acoustic wavelength comparable with the wavelength of light,
and hence to achieve a resolution comparable with an optical
microscope. Solids can support both longitudinal and transverse
acoustic waves. At surfaces a unique combination of the two known
as Raleigh waves can propagate, and in many circumstances these
dominate the contrast in acoustic microscopy. Following the
invention of scanning probe microscopes, it is now possible to use
an atomic force microscope to detect the acoustic vibration of a
surface with resolution in the nanometre range, thus beating the
diffraction limit by operating in the extreme near-field. This
second edition of Acoustic Microscopy has a major new chapter on
the technique and applications of acoustically excited probe
microscopy.
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.
This unique compendium introduces the field of numerical modelling
of water waves. The topics included the most widely used water wave
modelling approaches, presented in increasing order of complexity
and categorized into phase-averaged and phase-resolving at the
highest level.A comprehensive state-of-the-art review is provided
for each chapter, comprising the historical development of the
method, the most relevant models and their practical applications.
A full description on the method's underlying assumptions and
limitations are also provided. The final chapter features coupling
among different models, outlining the different types of
implementations, highlighting their pros and cons, and providing
numerous relevant examples for full context.The useful reference
text benefits professionals, researchers, academics, graduate and
undergraduate students in wave mechanics in general and coastal and
ocean engineering in particular.
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.
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 delivers a comprehensive and up-to-date treatment of
practical applications of metamaterials, structured media, and
conventional porous materials. With increasing levels of
urbanization, a growing demand for motorized transport, and
inefficient urban planning, environmental noise exposure is rapidly
becoming a pressing societal and health concern. Phononic and sonic
crystals, acoustic metamaterials, and metasurfaces can
revolutionize noise and vibration control and, in many cases,
replace traditional porous materials for these applications. In
this collection of contributed chapters, a group of international
researchers reviews the essentials of acoustic wave propagation in
metamaterials and porous absorbers with viscothermal losses, as
well as the most recent advances in the design of acoustic
metamaterial absorbers. The book features a detailed theoretical
introduction describing commonly used modelling techniques such as
plane wave expansion, multiple scattering theory, and the transfer
matrix method. The following chapters give a detailed consideration
of acoustic wave propagation in viscothermal fluids and porous
media, and the extension of this theory to non-local models for
fluid saturated metamaterials, along with a description of the
relevant numerical methods. Finally, the book reviews a range of
practical industrial applications, making it especially attractive
as a white book targeted at the building, automotive, and
aeronautic industries.
This book addresses the analysis of musical sounds from the
viewpoint of someone at the intersection between physicists,
engineers, piano technicians, and musicians. The study is
structured into three parts. The reader is introduced to a variety
of waves and a variety of ways of presenting, visualizing, and
analyzing them in the first part. A tutorial on the tools used
throughout the book accompanies this introduction. The mathematics
behind the tools is left to the appendices. Part Two provides a
graphical survey of the classical areas of acoustics that pertain
to musical instruments: vibrating strings, bars, membranes, and
plates. Part Three is devoted almost exclusively to the piano.
Several two- and three-dimensional graphical tools are introduced
to study various characteristics of pianos: individual notes and
interactions among them, the missing fundamental, inharmonicity,
tuning visualization, the different distribution of harmonic power
for the various zones of the piano keyboard, and potential uses for
quality control. These techniques are also briefly applied to other
musical instruments studied in earlier parts of the book. For
physicists and engineers there are appendices to cover the
mathematics lurking beneath the numerous graphs and a brief
introduction to Matlab (R) which was used to generate these graphs.
A website accompanying the book
(https://sites.google.com/site/analysisofsoundsandvibrations/)
contains: - Matlab (R) scripts - mp3 files of sounds - references
to YouTube videos - and up-to-date results of recent studies
This book is based on a series of lectures for an Astrophysics of
the Interstellar Medium (ISM) master's degree in Astrophysics and
Cosmology at Padova University. From the cold molecular phase in
which stars and planetary systems form, to the very hot coronal gas
that surrounds galaxies and galaxy clusters, the ISM is everywhere.
Studying its properties is vital for the exploration of virtually
any field in astronomy and cosmology. These notes give the student
a coherent and accurate mathematical and physical approach, with
continuous references to the real ISM in galaxies. The book is
divided into three parts. Part One introduces the equations of
fluid dynamics for a system at rest and acoustic waves, and then
explores the real ISM through the role of thermal conduction and
viscosity, concluding with a discussion of shock waves and
turbulence. In Part Two, the electromagnetic field is switched on
and its role in modulating shock waves and contrasting gravity is
studied. Part Three describes dust and its properties, followed by
the main stellar sources of energy. The last two chapters
respectively address the various components of the ISM and
molecular clouds and star formation.
Composites have been studied for more than 150 years, and interest
in their properties has been growing. This classic volume provides
the foundations for understanding a broad range of composite
properties, including electrical, magnetic, electromagnetic,
elastic and viscoelastic, piezoelectric, thermal, fluid flow
through porous materials, thermoelectric, pyroelectric,
magnetoelectric, and conduction in the presence of a magnetic field
(Hall effect). Exact solutions of the PDEs in model geometries
provide one avenue of understanding composites; other avenues
include microstructure-independent exact relations satisfied by
effective moduli, for which the general theory is reviewed;
approximation formulae for effective moduli; and series expansions
for the fields and effective moduli that are the basis of numerical
methods for computing these fields and moduli. The range of
properties that composites can exhibit can be explored either
through the model geometries or through microstructure-independent
bounds on the properties. These bounds are obtained through
variational principles, analytic methods, and Hilbert space
approaches. Most interesting is when the properties of the
composite are unlike those of the constituent materials, and there
has been an explosion of interest in such composites, now known as
metamaterials. The Theory of Composites surveys these aspects,
among others, and complements the new body of literature that has
emerged since the book was written. It remains relevant today by
providing historical background, a compendium of numerous results,
and through elucidating many of the tools still used today in the
analysis of composite properties. This book is intended for applied
mathematicians, physicists, and electrical and mechanical
engineers. It will also be of interest to graduate students.

This book reports on the 13th International Workshop on Railway
Noise (IWRN13), held on September 16-20, 2019, in Ghent, Belgium.
It gathers original peer-reviewed papers describing the latest
developments in railway noise and vibration, as well as
state-of-the-art reviews written by authoritative experts in the
field. The different papers cover a broad range of railway noise
and vibration topics, such as rolling noise, wheel squeal, noise
perception, prediction methods, measurements and monitoring, and
vehicle interior noise. Further topics include rail roughness, rail
corrugation and grinding, high-speed rail and aerodynamic noise,
structure-borne noise, ground-borne noise and vibration, and
resilient track forms. Policy, criteria and regulation are also
discussed. Offering extensive and timely information to both
scientists and engineers, this book will help them in their daily
efforts to identify, understand and solve problems related to
railway noise and vibration, and to achieve the ultimate goal of
reducing the environmental impact of railway systems.
Information is a core concept in animal communication: individuals
routinely produce, acquire, process and store information, which
provides the basis for their social life. This book focuses on how
animal acoustic signals code information and how this coding can be
shaped by various environmental and social constraints. Taking
birds and mammals, including humans, as models, the authors explore
such topics as communication strategies for "public" and "private"
signaling, static and dynamic signaling, the diversity of coded
information and the way information is decoded by the receiver. The
book appeals to a wide audience, ranging from bioacousticians,
ethologists and ecologists to evolutionary biologists. Intended for
students and researchers alike, it promotes the idea that Shannon
and Weaver's Mathematical Theory of Communication still represents
a strong framework for understanding all aspects of the
communication process, including its dynamic dimensions.
This book presents a technical solution to ensuring the noise
immunity of navigation systems in civil aviation aircrafts at the
stages of their terminal procedures. It highlights instrumental
precision approaches to landing and landing in automatic mode using
satellite and inertial radio navigation systems and ground-based
augmentation used as the primary means, in accordance with the ICAO
requirements. The book is intended for engineering and technical
specialists engaged in the development, manufacture and operation
of on-board radio electronic systems of aircrafts and ground-based
radio engineering support for flights, as well as graduate students
and senior students of radio engineering specialties. It is also
useful for professionals whose activities are related to air
traffic control.
What if history had a sound track? What would it tell us about
ourselves? Based on a thirty-part BBC Radio series and podcast,
Noise explores the human dramas that have revolved around sound at
various points in the last 100,000 years, allowing us to think in
fresh ways about the meaning of our collective past.
Though we might see ourselves inhabiting a visual world, our
lives have always been hugely influenced by our need to hear and be
heard. To tell the story of sound--music and speech, but also
echoes, chanting, drumbeats, bells, thunder, gunfire, the noise of
crowds, the rumbles of the human body, laughter, silence,
conversations, mechanical sounds, noisy neighbors, musical
recordings, and radio--is to explain how we learned to overcome our
fears about the natural world, perhaps even to control it; how we
learned to communicate with, understand, and live alongside our
fellow beings; how we've fought with one another for dominance; how
we've sought to find privacy in an increasingly noisy world; and
how we've struggled with our emotions and our sanity.
Oratory in ancient Rome was important not just for the words
spoken but for the sounds made--the tone, the cadence, the pitch of
the voice--how that voice might have been transformed by the
environment in which it was heard and how the audience might have
responded to it. For the Native American tribes first encountering
the European colonists, to lose one's voice was to lose oneself. In
order to dominate the Native Americans, European colonists went to
great effort to silence them, to replace their "demonic" "roars"
with the more familiar "bugles, speaking trumpets, and gongs."
Breaking up the history of sound into prehistoric noise, the age
of oratory, the sounds of religion, the sounds of power and revolt,
the rise of machines, and what he calls our "amplified age," Hendy
teases out continuities and breaches in our long relationship with
sound in order to bring new meaning to the human story.
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 explores the fascinating and intimate relationship
between music and physics. Over millennia, the playing of, and
listening to music have stimulated creativity and curiosity in
people all around the globe. Beginning with the basics, the authors
first address the tonal systems of European-type music, comparing
them with those of other, distant cultures. They analyze the
physical principles of common musical instruments with emphasis on
sound creation and particularly charisma. Modern research on the
psychology of musical perception - the field known as
psychoacoustics - is also described. The sound of orchestras in
concert halls is discussed, and its psychoacoustic effects are
explained. Finally, the authors touch upon the role of music for
our mind and society. Throughout the book, interesting stories and
anecdotes give insights into the musical activities of physicists
and their interaction with composers and musicians.
Sound, devoid of meaning, would not matter to us. It is the
information sound conveys that helps the brain to understand its
environment. Sound and its underlying meaning are always associated
with time and space. There is no sound without spatial properties,
and the brain always organizes this information within a
temporal-spatial framework. This book is devoted to understanding
the importance of meaning for spatial and related further aspects
of hearing, including cross-modal inference. People, when exposed
to acoustic stimuli, do not react directly to what they hear but
rather to what they hear means to them. This semiotic maxim may not
always apply, for instance, when the reactions are reflexive. But,
where it does apply, it poses a major challenge to the builders of
models of the auditory system. Take, for example, an auditory model
that is meant to be implemented on a robotic agent for autonomous
search-&-rescue actions. Or think of a system that can perform
judgments on the sound quality of multimedia-reproduction systems.
It becomes immediately clear that such a system needs * Cognitive
capabilities, including substantial inherent knowledge * The
ability to integrate information across different sensory
modalities To realize these functions, the auditory system provides
a pair of sensory organs, the two ears, and the means to perform
adequate preprocessing of the signals provided by the ears. This is
realized in the subcortical parts of the auditory system. In the
title of a prior book, the term Binaural Listening is used to
indicate a focus on sub-cortical functions. Psychoacoustics and
auditory signal processing contribute substantially to this area.
The preprocessed signals are then forwarded to the cortical parts
of the auditory system where, among other things, recognition,
classification, localization, scene analysis, assignment of
meaning, quality assessment, and action planning take place. Also,
information from different sensory modalities is integrated at this
level. Between sub-cortical and cortical regions of the auditory
system, numerous feedback loops exist that ultimately support the
high complexity and plasticity of the auditory system. The current
book concentrates on these cognitive functions. Instead of
processing signals, processing symbols is now the predominant
modeling task. Substantial contributions to the field draw upon the
knowledge acquired by cognitive psychology. The keyword Binaural
Understanding in the book title characterizes this shift. Both
books, The Technology of Binaural Listening and the current one,
have been stimulated and supported by AABBA, an open research group
devoted to the development and application of models of binaural
hearing. The current book is dedicated to technologies that help
explain, facilitate, apply, and support various aspects of binaural
understanding. It is organized into five parts, each containing
three to six chapters in order to provide a comprehensive overview
of this emerging area. Each chapter was thoroughly reviewed by at
least two anonymous, external experts. The first part deals with
the psychophysical and physiological effects of Forming and
Interpreting Aural Objects as well as the underlying models. The
fundamental concepts of reflexive and reflective auditory feedback
are introduced. Mechanisms of binaural attention and attention
switching are covered-as well as how auditory Gestalt rules
facilitate binaural understanding. A general blackboard
architecture is introduced as an example of how machines can learn
to form and interpret aural objects to simulate human cognitive
listening. The second part, Configuring and Understanding Aural
Space, focuses on the human understanding of complex
three-dimensional environments-covering the psychological and
biological fundamentals of auditory space formation. This part
further addresses the human mechanisms used to process information
and interact in complex reverberant environments, such as concert
halls and forests, and additionally examines how the auditory
system can learn to understand and adapt to these environments. The
third part is dedicated to Processing Cross-Modal Inference and
highlights the fundamental human mechanisms used to integrate
auditory cues with cues from other modalities to localize and form
perceptual objects. This part also provides a general framework for
understanding how complex multimodal scenes can be simulated and
rendered. The fourth part, Evaluating Aural-scene Quality and
Speech Understanding, focuses on the object-forming aspects of
binaural listening and understanding. It addresses cognitive
mechanisms involved in both the understanding of speech and the
processing of nonverbal information such as Sound Quality and
Quality-of- Experience. The aesthetic judgment of rooms is also
discussed in this context. Models that simulate underlying human
processes and performance are covered in addition to techniques for
rendering virtual environments that can then be used to test these
models. The fifth part deals with the Application of Cognitive
Mechanisms to Audio Technology. It highlights how cognitive
mechanisms can be utilized to create spatial auditory illusions
using binaural and other 3D-audio technologies. Further, it covers
how cognitive binaural technologies can be applied to improve human
performance in auditory displays and to develop new auditory
technologies for interactive robots. The book concludes with the
application of cognitive binaural technologies to the next
generation of hearing aids.
