Duke University Press Aurality
Book SynopsisIn this audacious book, Ana María Ochoa Gautier explores how listening has been central to the production of notions of language, music, voice, and sound that determine the politics of life. Drawing primarily from nineteenth-century Colombian sources, Ochoa Gautier locates sounds produced by different living entities at the juncture of the human and nonhuman. Her 'acoustically tuned' analysis of a wide array of texts reveals multiple debates on the nature of the aural. These discussions were central to a politics of the voice harnessed in the service of the production of different notions of personhood and belonging. In Ochoa Gautier''s groundbreaking work, Latin America and the Caribbean emerge as a historical site where the politics of life and the politics of expression inextricably entangle the musical and the linguistic, knowledge and the sensorial. Trade Review"Speaking from the intersection of sound studies, Latin American studies, and the history of natural history and musicology, this book shifts the terrain upon which all of those fields have comfortably settled. Scholars of sound studies will need to take note of Ochoa’s challenges to European or North American framings." -- Alejandra Bronfman * Hispanic American Historical Review *“Gautier’s work is tremendously useful. A challenging and rewarding read, I recommend her work to persons who are seriously interested in new approaches to retelling the history of any nation.” -- Julian Ledford * AmeriQuests *"Aurality is a significant contribution to the burgeoning field of sound studies. Ana Marıa Ochoa Gautier adeptly guides the reader across complex scales of analysis using well-selected historical case studies.... Aurality achieves its goal of establishing a critical vantage point for making sense of the contemporary transformations that are shaping the 21st." -- William Hope * American Ethnologist *"Ochoa Gautier provides a vitally important account of the intricate and heterogeneous modes of knowing, being, becoming, and belonging that continue to resonate in the postcolonial lettered city." -- Leonardo Cardoso * American Anthropologist *"The volume is a must for enthusiasts of sound studies and/or Colombian history. Ochoa Gautier has done a fine job chronicling the way in which the aural played a key role in the definition of a relation between humankind and the body politics of the nation-state. It deserves wide recognition and ample endorsement." -- Héctor Fernández L'Hoeste * EIAL *"This book raises important questions about the role of sound and efforts to categorise it in defining the relationship between the human and the non-human, and between different social groups within Colombian society.... Aurality will undoubtedly serve the specialist researcher well and it is to be hoped that the rich lines of inquiry it opens up will receive further attention in future." -- Anna Cant * Journal of Latin American Studies *"Aurality is a rich and complex book that raises important questions about colonialism and modernity, personhood and nation. Ochoa Gautier has made an important contribution to Colombian historiography, certainly meeting her aim to explore 'the relationship between listening and the voice as a part of the history of the relation between the colonial and the modern'. . . . It will be difficult to read history in the same way again." -- Meri L. Clark * The Latin Americanist *Table of ContentsPreface and Acknowledgments ix Introduction.

Boydell & Brewer Ltd How We Hear Music
Book SynopsisCovers much of the acoustics a student needs, without mathematics or scientific background.Choice Outstanding Academic Title A survey of intervals and scales, tone pitch, loudness and time in Western music raises many questions about the hearing mechanism and throws doubt on the conventional role of harmonics. James Beament's account of how musical sounds are coded by the ear and the brain's processing units, provides answers to most of these questions. It concludes that music started with simple instruments which voices imitated, and that the need to know sound direction determined the characteristics of hearing. This book will interest students, practising musicians and music psychologists, and assumes no scientific knowledge. The late ProfessorSir JAMES BEAMENT was a distinguished scientist and musician, who taught and examined music students at Cambridge University.Trade ReviewInformed by a broad expertise comprehending all of the disciplines for which human hearing is pertinent. Beament['s] model for the hearing of music...is not only the most speculative section of the book but also the most brilliant. Recommended warmly... it should find a niche in virtually every college, university and professional music library. * CHOICE *Table of ContentsPart 1 Preliminaries. Part 2 Aural archaeology.

Duke University Press A Resonant Ecology
Book SynopsisIn A Resonant Ecology, Max Ritts traces how sound’s integration into the environmental politics of Canada’s North Coast has paved the way for massive industrial expansion. While conservationists hope that the dissemination of whale songs and other nature sounds will showcase the beauty of local wildlife for people around the world, Ritts reveals how colonial capitalism can co-opt sonic efforts to protect the coast. He demonstrates how digital technologies allow industry to sonically map new shipping lanes and facilitate new ways of experiencing sound—premised not on listening, but on sound’s exploitable status as a data resource. By outlining how sound can both perpetuate and refuse capitalist colonialism, Ritts challenges the idea that the sonic realm is inherently liberatory and reveals sound to be a powerfully uncertain object. Through a situated geographical approach, he makes the case that only a decolonial and multigenerational environmental politic

Springer Nature Switzerland AG The Physics of Music and Color: Sound and Light
Book SynopsisThis undergraduate textbook aids readers in studying music and color, which involve nearly the entire gamut of the fundamental laws of classical as well as atomic physics. The objective bases for these two subjects are, respectively, sound and light. Their corresponding underlying physical principles overlap greatly: Both music and color are manifestations of wave phenomena. As a result, commonalities exist as to the production, transmission, and detection of sound and light. Whereas traditional introductory physics textbooks are styled so that the basic principles are introduced first and are then applied, this book is based on a motivational approach: It introduces a subject with a set of related phenomena, challenging readers by calling for a physical basis for what is observed. A novel topic in the first edition and this second edition is a non-mathematical study of electric and magnetic fields and how they provide the basis for the propagation of electromagnetic waves, of light in particular. The book provides details for the calculation of color coordinates and luminosity from the spectral intensity of a beam of light as well as the relationship between these coordinates and the color coordinates of a color monitor. The second edition contains corrections to the first edition, the addition of more than ten new topics, new color figures, as well as more than forty new sample problems and end-of-chapter problems. The most notable additional topics are: the identification of two distinct spectral intensities and how they are related, beats in the sound from a Tibetan bell, AM and FM radio, the spectrogram, the short-time Fourier transform and its relation to the perception of a changing pitch, a detailed analysis of the transmittance of polarized light by a Polaroid sheet, brightness and luminosity, and the mysterious behavior of the photon.The Physics of Music and Color is written at a level suitable for college students without any scientific background, requiring only simple algebra and a passing familiarity with trigonometry. The numerous problems at the end of each chapter help the reader to fully grasp the subject.Table of ContentsChapter1: Introductory Remarks.- Chapter2: The Vibrating String.- Chapter3: The Nature of Sound; The Vibrating Air Column.- Chapter4: Energy.- Chapter5: Electricity & Magnetism.- Chapter6: The Atom as a Source of Light.- Chapter7: The Principle of Superposition.- Chapter 8: Complex Waves.- Chapter9: Propagation Phenomena.- Chapter10: The Ear.- Chapter11: Psychoacoustics.- Chapter12: Tuning, Intonation, and Temperament - Choosing Frequencies for Musical Notes.- Chapter13: The Eye.- Chapter14: Characterizing Light Sources, Color Filters, and Pigments.-Chapter15: Theory of Color Vision.- Appendices.

Springer Nature Switzerland AG Auralization: Fundamentals of Acoustics, Modelling, Simulation, Algorithms and Acoustic Virtual Reality
Book SynopsisAuralization is the technique of creation and reproduction of sound on the basis of computer data. With this tool it is possible to predict the character of sound signals which are generated at the source and modified by reinforcement, propagation and transmission in systems such as rooms, buildings, vehicles or other technical devices. This book is organized as a comprehensive collection of the basics of sound and vibration, acoustic modelling, simulation, signal processing and audio reproduction. With some mathematical prerequisites, the readers will be able to follow the main strategy of auralization easily and work out their own implementations of auralization in various fields of application in architectural acoustics, acoustic engineering, sound design and virtual reality. For readers interested in basic research, the technique of auralization may be useful to create sound stimuli for specific investigations in linguistic, medical, neurological and psychological research, and in the field of human-machine interaction.Table of ContentsChapter1: Fundamentals of acoustics.- Chapter2: Sound sources.- Chapter3: Sound propagation.- Chapter4: Sound fields in cavities and in rooms.- Chapter5: Structure-borne sound.- Chapter6: Psychoacoustics.- Chapter7: Signal processing for auralization.- Chapter8: Characterization of sources.- Chapter9: Convolution and binaural sound synthesis.- Chapter10: Simulation methods.- Chapter11: Simulation of sound in rooms.- Chapter12: Simulation and auralization of outdoor sound propagation.- Chapter13: Simulation and auralization of airborne sound insulation.- Chapter14: Simulation and auralization of structure-borne sound.- Chapter15: Transfer path analysis and synthesis.- Chapter16: Filter construction for real-time processing.- Chapter17: 3D sound reproduction.- Chapter18: Acoustic Virtual Reality systems.

Springer Nature Switzerland AG Thermoacoustic Instability: A Complex Systems
Book SynopsisThis book systematically presents the consolidated findings of the phenomenon of self-organization observed during the onset of thermoacoustic instability using approaches from dynamical systems and complex systems theory. Over the last decade, several complex dynamical states beyond limit cycle oscillations such as quasiperiodicity, frequency-locking, period-n, chaos, strange non-chaos, and intermittency have been discovered in thermoacoustic systems operated in laminar and turbulent flow regimes. During the onset of thermoacoustic instability in turbulent systems, an ordered acoustic field and large coherent vortices emerge from the background of turbulent combustion. This emergence of order from disorder in both temporal and spatiotemporal dynamics is explored in the contexts of synchronization, pattern formation, collective interaction, multifractality, and complex networks. For the past six decades, the spontaneous emergence of large amplitude, self-sustained, tonal oscillations in confined combustion systems, characterized as thermoacoustic instability, has remained one of the most challenging areas of research. The presence of such instabilities continues to hinder the development and deployment of high-performance combustion systems used in power generation and propulsion applications. Even with the advent of sophisticated measurement techniques to aid experimental investigations and vast improvements in computational power necessary to capture flow physics in high fidelity simulations, conventional reductionist approaches have not succeeded in explaining the plethora of dynamical behaviors and the associated complexities that arise in practical combustion systems. As a result, models and theories based on such approaches are limited in their application to mitigate or evade thermoacoustic instabilities, which continue to be among the biggest concerns for engine manufacturers today. This book helps to overcome these limitations by providing appropriate methodologies to deal with nonlinear thermoacoustic oscillations, and by developing control strategies that can mitigate and forewarn thermoacoustic instabilities. The book is also beneficial to scientists and engineers studying the occurrence of several other instabilities, such as flow-induced vibrations, compressor surge, aeroacoustics and aeroelastic instabilities in diverse fluid-mechanical environments, to graduate students who intend to apply dynamical systems and complex systems approach to their areas of research, and to physicists who look for experimental applications of their theoretical findings on nonlinear and complex systems.Table of Contents1 Introduction 1.1 Introduction to thermoacoustic instability and its consequences 1.2

Springer Verlag, Singapore Acoustic Communication in Animals: From Insect
Book SynopsisThis book is the first volume of the bioacoustics series published by the Society for Bioacoustics. This volume provides an overview of the advances and recent topics in acoustic communication in various animals. Most animals produce vibrations and sounds by moving their body parts, including vocal organs. These sounds can be research targets of bioacoustics studies. How animals use these sounds, especially in inter-individual relationships, is the focus of this volume, “Acoustic Communication in Animals”. The authors’ expertise varies from molecular biology, neurobiology to psychology, and human brain imaging. Their research subjects range from invertebrates to humans. Despite the variety of topics, chapters are developed under the consideration of ethology and evolution. Readers will recognize the profundity of the topics in each chapter. In addition, the view and understanding of natural sound sequences produced by animals can vary among different cultures. Research from Japan and regions that have been underrepresented in previous literature can offer new ideas and unique perspectives in the study of bioacoustics. Readers can grasp the progress of this research field in a broad range of species in one book. The book presents multi- and interdisciplinary topics and appeals to researchers and students in fields including psychology, physiology, zoology, ethology, and neurosciences.Table of ContentsChapter 1. Using knowledge about human vocal behaviour to understand acoustic communication in animals and the evolution of language and musicChapter 2.
