Discusses the acoustics and vibrations theories within the framework of modern communication and information science. Topics include: the techniques of signal analysis; sound propagation; intensity distributions; subjective and physiological responses to sound fields; and sound field control.
Sound is integral to how we experience the world, in the form of noise as well as music. But what is sound? What is the physical basis of pitch and harmony? And how are sound waves exploited in musical instruments? In this Very Short Introduction Mike Goldsmith looks at the science of sound and explores sound in different contexts, covering the audible and inaudible, sound underground and underwater, accoustic and electric, and hearing in humans and animals. He also considers the problem of sound out of place - noise and its reduction.

These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
Worship Space Acoustics is a unique guide to the design, construction, and use of religious facilities for optimum acoustics. The book is divided into two parts: Part 1 discusses methods and techniques of room optimization – how the acoustics of large and small spaces are designed, implemented, and adjusted, and how acoustical privacy is attained; noise and its control as well as sound reinforcement and numerical and physical modeling techniques. Part 2 provides the architect, student, and lay-person a review of the characteristics of the religious services pertinent to various beliefs and how these are provided for in the acoustic design of spaces in synagogues, churches, and mosques.Key Features • Covers the design, construction, and use of religious facilities for optimum acoustics • Presents the historical background to existing practice, problems, and solutions, to deepen understanding for those involved in design, construction and use • Illustrates both the similarities and differences between facilities for different religious groups • Offers a unique reference for those who teach and study, both in architecture and in religious education
Providing a wealth of information on fundamental topics in the areas of linear air and underwater acoustics, as well as space-time signal processing, this book provides real-world design and analysis equations. As a consequence of the interdisciplinary nature of air and underwater acoustics, the book is divided into two parts: Acoustic Field Theory and Space-Time Signal Processing. It covers the fundamentals of acoustic wave propagation as well as the fundamentals of aperture theory, array theory, and signal processing. Starting with principles and using a consistent, mainly standard notation, this book develops, in detail, basic results that are useful in a variety of air and underwater acoustic applications. Numerous figures, examples, and problems are included.
In this two-volume Handbook, contributors address the tendency to discuss musical imagination through terms like compositional creativity or performance technique, correcting the current bias towards visual imagination to instead highlight the many forms of sonic and musical imagination.
Whether social, cultural, or individual, the act of imagination always derives from a pre-existing context. For example, we can conjure an alien's scream from previously heard wildlife recordings or mentally rehearse a piece of music while waiting for a train. This process is no less true for the role of imagination in sonic events and artifacts. Many existing works on sonic imagination tend to discuss musical imagination through terms like compositional creativity or performance technique. In this two-volume Handbook, contributors shift the focus of imagination away from the visual by addressing the topic of sonic imagination and expanding the field beyond musical compositional creativity and performance technique into other aural arenas where the imagination holds similar power. Topics covered include auditory imagery and the neurology of sonic imagination; aural hallucination and illusion; use of metaphor in the recording studio; the projection of acoustic imagination in architectural design; and the design of sound artifacts for cinema and computer games.
Hearing, health, and technologies are entangled in multi-faceted ways. This edited volume addresses this complex relationship by arguing that modern hearing was and is increasingly linked to and mediated by technological innovations. By providing a set of original interdisciplinary investigations that shed new light on the history, theory, and practices of hearing techniques, it is able to explore the heterogeneous entanglements of sound, hearing practices, technologies, and health issues. As the first book to bring together historians, scholars from media studies, social sciences, cultural studies, acoustics, and neuroscientists, the volume discusses modern technologies and their decisive impact on how "normal" hearing, enhanced and smart hearing, as well as hearing impairment have been configured. It brings both new insights into the histories of hearing technologies as well as allowing us to better understand how enabling hearing technologies have currently been unfolding an increasingly hybrid ecology engaging smart hearing devices and offering stress-free hearing and acoustic well-being in novel auditory environments. The volume will be of interest to all scholars and students of disability studies, sound studies, sociology of health and illness, medical history, health and society, as well as those interested in the practices and techniques of self-monitored and smart hearing.
How we experience space by listening: the concepts of aural architecture, with examples ranging from Gothic cathedrals to surround sound home theater. We experience spaces not only by seeing but also by listening. We can navigate a room in the dark, and "hear" the emptiness of a house without furniture. Our experience of music in a concert hall depends on whether we sit in the front row or under the balcony. The unique acoustics of religious spaces acquire symbolic meaning. Social relationships are strongly influenced by the way that space changes sound. In Spaces Speak, Are You Listening?, Barry Blesser and Linda-Ruth Salter examine auditory spatial awareness: experiencing space by attentive listening. Every environment has an aural architecture.The audible attributes of physical space have always contributed to the fabric of human culture, as demonstrated by prehistoric multimedia cave paintings, classical Greek open-air theaters, Gothic cathedrals, acoustic geography of French villages, modern music reproduction, and virtual spaces in home theaters. Auditory spatial awareness is a prism that reveals a culture's attitudes toward hearing and space. Some listeners can learn to "see" objects with their ears, but even without training, we can all hear spatial geometry such as an open door or low ceiling. Integrating contributions from a wide range of disciplines—including architecture, music, acoustics, evolution, anthropology, cognitive psychology, audio engineering, and many others—Spaces Speak, Are You Listening? establishes the concepts and language of aural architecture. These concepts provide an interdisciplinary guide for anyone interested in gaining a better understanding of how space enhances our well-being. Aural architecture is not the exclusive domain of specialists. Accidentally or intentionally, we all function as aural architects.
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 entrée 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
