One of the most remarkable books on sound around. The
author charts the geography and history of our sonic environment
— our soundscape. No type of noise, roar, clatter, hiss, twang, vibration, or audible rhythm escapes his notice. For instance, he discovered European towns hum at harmonies of G sharp (50 hertz power supply), while America drones at B natural (60 hertz). He divides our surroundings into dominant tonal patterns, mapping out the evolution of sound on Earth. Other topics discussed: Sacred sounds, the concert hall as a substitute for outdoor life, the intent of Muzak, sounds of water creatures, sound imperialism, ceremonies about silence, and taboo sounds. A marvelous, awakening book.
