Book excerpt: How sound and its atmospheres transform architecture Acoustic atmospheres can be fleeting, elusive, or short-lived. Sometimes they are constant, but more often they change from one moment to the next, forming distinct impressions each time we visit certain places. Stable or dynamic, acoustic atmospheres have a powerful effect on our spatial experience, sometimes even more so than architecture itself. This book explores the acoustic atmospheres of diverse architectural environments, in terms of scale, program, location, or historic period—providing an overview of how acoustic atmospheres are created, perceived, experienced, and visualized. The contributors explore how sound and its atmospheres transform architecture and space. Their essays demonstrate that sound is a tangible element in the design and staging of atmospheres and that it should become a central part of the spatial explorations of architects, designers, and urban planners. The Sound of Architecture will be of interest to architectural historians, theorists, students, and practicing architects, who will discover how acoustic atmospheres can be created without complex and specialized engineering. It will also be of value to scholars working in the field of history of emotions, as it offers evocative descriptions of acoustic atmospheres from diverse cultures and time periods.
