Listening Devices

From 1940 to 1990, new machines and devices radically changed listening to music. Small and large single records, new kinds of jukeboxes and loudspeaker systems not only made it possible to playback music in a different way, they also evidence a fundamental transformation of music and listening itself. Taking the media and machines through which listening took place during this period, Listening Devices develops a new history of listening.Although these devices were (and often still are) easily accessible, up to now we have no concept of them. To address this gap, this volume proposes the term “listening device.” In conjunction with this concept, the book develops an original and fruitful method for exploring listening as a historical subject that has been increasingly organized in relation to technology. Case studies of four listening devices are the points of departure for the analysis, which leads the reader down unfamiliar paths, traversing the popular sound worlds of 1950s rock 'n' roll culture and the disco and club culture of the 1970s and 1980s. Despite all the characteristics specific to the different listening devices, they can nevertheless be compared because of the fundamental similarities they share: they model and manage listening, they actively mediate between the listener and the music heard, and it is this mediation that brings both listener and the music listened to into being. Ultimately, however, the intention is that the listening devices themselves should not be heard so that the music they playback can be heard. Thus, they take the history of listening to its very limits and confront it with its “other”-a history of non-listening. The book proposes “listening device” as a key concept for sound studies, popular music studies, musicology, and media studies. With this conceptual key, a new, productive understanding of past music and sound cultures of the pre-digital era can be unlocked, and, not least, of the listening culture of the digital present.

“Process Plant Equipment Book is another great publication from Wiley as a reference book for final year students as well as those who will work or are working in chemical production plants and refinery...” -Associate Prof. Dr. Ramli Mat, Deputy Dean (Academic), Faculty of Chemical Engineering, Universiti Teknologi Malaysia “...give[s] readers access to both fundamental information on process plant equipment and to practical ideas, best practices and experiences of highly successful engineers from around the world... The book is illustrated throughout with numerous black & white photos and diagrams and also contains case studies demonstrating how actual process plants have implemented the tools and techniques discussed in the book. An extensive list of references enables readers to explore each individual topic in greater depth...” –Stainless Steel World and Valve World, November 2012 Discover how to optimize process plant equipment, from selection to operation to troubleshooting From energy to pharmaceuticals to food, the world depends on processing plants to manufacture the products that enable people to survive and flourish. With this book as their guide, readers have the information and practical guidelines needed to select, operate, maintain, control, and troubleshoot process plant equipment so that it is efficient, cost-effective, and reliable throughout its lifetime. Following the authors' careful explanations and instructions, readers will find that they are better able to reduce downtime and unscheduled shutdowns, streamline operations, and maximize the service life of processing equipment. Process Plant Equipment: Operation, Control, and Reliability is divided into three sections: Section One: Process Equipment Operations covers such key equipment as valves, pumps, cooling towers, conveyors, and storage tanks Section Two: Process Plant Reliability sets forth a variety of tested and proven tools and methods to assess and ensure the reliability and mechanical integrity of process equipment, including failure analysis, Fitness-for-Service assessment, engineering economics for chemical processes, and process component function and performance criteria Section Three: Process Measurement, Control, and Modeling examines flow meters, process control, and process modeling and simulation Throughout the book, numerous photos and diagrams illustrate the operation and control of key process equipment. There are also case studies demonstrating how actual process plants have implemented the tools and techniques discussed in the book. At the end of each chapter, an extensive list of references enables readers to explore each individual topic in greater depth. In summary, this text offers students, process engineers, and plant managers the expertise and technical support needed to streamline and optimize the operation of process plant equipment, from its initial selection to operations to troubleshooting.
