Watch this video ad-free on Nebula: https://nebula.tv/videos/not-just-bikes-cities-aren-t-loud-cars-are-loud 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. This video explores the problem that farting cars, farting motorcycles, and farting mopeds create in our cities.
