Electroacoustic devices such as microphones and loudspeakers are used everywhere from cars and mobile phones to homes, places of worship, and sports arenas. They are a key part of the modern communication society, helping to transmit information to our ears. A contemporary introduction to the subject, Electroacoustics explains the scientific and engineering principles behind the design of these sound transducers. It also examines the compromises that are necessary when designing transducers for use in the real world. Learn about Ultrasonic Transducers, Loudspeaker Enclosure Design, and More This accessible textbook book is based on the author’s extensive experience teaching electroacoustics to advanced graduate and graduate students. He uses the concept of electrical circuit analogies to help readers quickly grasp the fundamentals of acoustical and mechanical systems. The book covers both traditional electrodynamic audio and ultrasonic transducers and includes up-to-date material on arrays, planar transducers, loudspeaker enclosure design, and more. To meet the needs of a broad range of readers, the book also includes background material on room acoustics, electrical circuits, and electrical filters. Electroacoustic theory is explained in an easy-to-read style without resorting to matrix theory. Throughout, a wealth of illustrations and exercises make the ideas more concrete. Get a Solid Foundation in Electroacoustic Engineering Principles The book emphasizes multidisciplinary engineering principles, preparing students for the broad range of applications they may encounter in their research as well as later in their careers. The modern treatment of transducers also makes this a valuable reference for transducer designers, acoustical consultants, hobbyists, and anyone involved in electroacoustic design.

The transformation of acoustics into electro-acoustics, a field at the intersection of science and technology, guided by electrical engineering, industry, and the military. At the end of the nineteenth century, acoustics was a science of musical sounds; the musically trained ear was the ultimate reference. Just a few decades into the twentieth century, acoustics had undergone a transformation from a scientific field based on the understanding of classical music to one guided by electrical engineering, with industrial and military applications. In this book, Roland Wittje traces this transition, from the late nineteenth-century work of Hermann Helmholtz to the militarized research of World War I and media technology in the 1930s. Wittje shows that physics in the early twentieth century was not only about relativity and atomic structure but encompassed a range of experimental, applied, and industrial research fields. The emergence of technical acoustics and electroacoustics illustrates a scientific field at the intersection of science and technology. Wittje starts with Helmholtz's and Rayleigh's work and its intersection with telegraphy and early wireless, and continues with the industrialization of acoustics during World War I, when sound measurement was automated and electrical engineering and radio took over the concept of noise. Researchers no longer appealed to the musically trained ear to understand sound but to the thinking and practices of electrical engineering. Finally, Wittje covers the demilitarization of acoustics during the Weimar Republic and its remilitarization at the beginning of the Third Reich. He shows how technical acoustics fit well with the Nazi dismissal of pure science, representing everything that “German Physics” under National Socialism should be: experimental, applied, and relevant to the military.

This book illuminates the development of electronic and computer music in East Asia, presented by authors from these countries and territories (China, Japan, Korea, and Taiwan). The scholars bring forward the cultural complexities and conflicts involved in their diverse encounters with new music technology and modern aesthetics. How electronic music attracted the interest of composers from East Asia is quite varied – while composers and artists in Japan delved into new sounds and music techniques and fostered electronic music quite early on; political, sociological, and artistic conditions pre-empted the adoption of electronic music techniques in China until the last two decades of the twentieth century. Korean and Taiwanese perspectives contribute to this rare opportunity to re-examine, under a radically different set of cultural preconditions, the sweeping musical transformation that similarly consumed the West. Special light is shed on prominent composers, such as Sukhi Kang, Toshiro Mayuzumi, Toru Takemitsu, and Xiaofu Zhang. Recent trends and new directions which are observed in these countries are also addressed, and the volume shows how the modern fusion of music and technology is triangulated by a depth of culture and other social forces. This book was originally published as a special issue of Contemporary Music Review.

Electroacoustic transducers (EAT) are devices, which transform electric energy to energy of acoustic fluctuations. Principles of action, design of transducers for work in air and water as well as for non-destructive control are described in the book. New technologies of designing EAT, not only expanding designing possibilities, are described. They also allow to create transducers with improved characteristics. In particular, methods to increase target capacity (sound pressure), decrease working (resonant) frequency of transducers and expand frequencies of projectors and sound receivers are developed. Methods and control units of transducers in batch production of transducers are described, too.

Passive components and discrete devices form the bedrocks on which all modern electronic circuits are built. This Pocket Book is a single volume applications guide to the most popular and useful of these devices, containing 670 diagrams, tables and carefully selected practical circuits. Throughout the Pocket Book great emphasis is placed on practical user information and circuitry. All of the active devices used are modestly priced and readily available.The book is split into twenty chapters. The first three explain important practical features of the ranges of modern passive electrical components, including relays, meters, motors, sensors and transducers. Chapters 4 to 6 deal with the design ofpractical attenuators, filters, and 'bridge' circuits. The remaining fourteen chapters deal with specific types of discrete semiconductor device, including various types of diode, transistors, JFETs, MOSFETs, VMOS devices, UJTs, SCRs, TRIACs, and various optoelectronic devices. This easy-to-read, concise, highly practical and largely non-mathematical volume is aimed directly at engineers, technicians, students and competent experimenters who can build a design directly from a circuit diagram, and if necessary modify it to suit individual needs. Ray Marston is the author of the multi-volume series of Newnes Circuits Manuals. His magazine articles on circuit design appear regularly in a wide range of publications worldwide.

Deaf People and Society is an authoritative text that emphasizes the complexities of being D/deaf, DeafBlind, Deaf-Disabled, or hard of hearing, drawing on perspectives from psychology, education, and sociology. This book also explores how the lives of these individuals are impacted by decisions made by professionals in clinics, schools, or other settings. This new edition offers insights on areas critical to Deaf Studies and Disability Studies, with particular emphasis on multiculturalism and multilingualism, as well as diversity, equity, and inclusion. Accessibly written, the chapters include objectives and suggested further reading that provides valuable leads and context. Additionally, these chapters have been thoroughly revised and incorporate a range of relevant topics including etiologies of deafness; cognition and communication; bilingual, bimodal, and monolingual approaches to language learning; childhood psychological issues; psychological and sociological viewpoints of deaf adults; the criminal justice system and deaf people; psychodynamics of interaction between deaf and hearing people; and future trends. The book also includes case studies covering hearing children of deaf adults, a young deaf adult with mental illness, and more. Written by a seasoned D/deaf/hard of hearing and hearing bilingual team, this unique text continues to be the go-to resource for students and future professionals interested in working with D/deaf, DeafBlind, and hard-of-hearing persons. Its contents will resonate with anyone interested in serving and enhancing their knowledge of their lived experiences of D/deaf, DeafBlind, Deaf-Disabled, and hard-of-hearing people and communities.
