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.

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.

Providing cutting-edge research on nanoelectronics and photonic devices and its application in future integrated circuits, this state-of-the-art book tackles the challenges of the different detailed theoretical and analytical models of solving the problems of various nanodevices. The volume also explores from different angles the roles of material composition and choice of materials that now play the most critical role in determining outcomes of low-dimensional nanoelectronic devices. The applications of those findings are extremely beneficial for the computing and telecommunication industries. Beginning with a solid theoretical background for every chapter, this volume covers the hottest areas of present-day electronic engineering. The continuous miniaturization of devices, components, and systems requires corresponding cutting-edge theoretical analysis supported by simulated findings before actual fabrication. That purpose is given maximum focus in this volume, which has interdisciplinary appeal, making it a comprehensive technological volume that deals with underlying aspects of physics, materials, structures in nano-regime, and the corresponding end-product in the form of devices.
