Urban noise is a common problem, and the vast majority of it is created by motor vehicles. Noise is far too often dismissed as a minor nuisance, rather than the legitimate health issue that it is. The book "Curbing Traffic" has a chapter about the health impacts of noise pollution. I explore the research in the book, and visit Delft, the city that is highlighted in the book as being a shining example of what can happen when noise pollution is taken seriously. - Not Just Bikes
