Lessening the Severe Health Effects of Traffic Noise in Cities by Emission Reductions (28 page pdf, Tor Kihlman, Wolfgang Kropp, and William Lang, The CAETS Noise Control Technology Committee and the International Institute of Noise Control Engineering, May 2014)

Today we review a report that looks at the second biggest environmental cause of health problems after air pollution, noise. As with air pollution, the single biggest source is road traffic from the interaction between tires and pavement or “rolling noise”. Solutions call for “quiet pavements” and improved design of tires although the authors report that present regulations and that most actions by government and industry fall well short of solving the problem. An interesting point was made about safety concerns about electric cars being too quiet to the point that government wants to require noise emitters – a step that is seen as unnecessary and counterproductive. Again, as with air pollution, an effective solution is to reduce roads traffic by promoting quiet forms of transportation, such as walking and cycling. Steps to reduce road noise would also benefit efforts to reduce greenhouse gases and climate change impacts.
