Do you enjoy listening to music while driving your car? Do you find radio traffic information indispensable? Do you appreciate the moments in between work and home in which you can listen to or sing along with whatever you like?This book shows how we created auditory privacy in our Western cars, making it feel sound and safe, even though automobiles were highly noisy things at the beginning of the twentieth century. It explains how engineers in the automotive industry found pride in making car engines quieter once they realized that noise stood for inefficiently running machines. It follows them in struggling with the sounds audible within the car after the automobile had become a closed vehicle. It tells how noise-induced fatigue became an issue once the car became a mass means for touring across the country. It unravels the initial societal concerns about the dangers of car radio, and how radio traffic information became crucial for avoiding traffic jams. And it explores how car drivers once listened to their cars’ engines to diagnose car problems, and are now supposed to buy a car because of its high quality sound design. This book is about the sounds of car engines, tires, wipers, blinkers, warning signals, in-car audio systems and, ultimately, about how we became used to listen while driving.
