Percentage of National Population Exposed to Ground Transportation Noise in Selected Countries
The above table illustrates the wide diffusion of noise pollution in developed countries, particularly for road transportation noise. This is in part explained by the fact that most residential areas are served by high capacity road transportation infrastructure where high speed noise adds to the local circulation. It is likely that limited improvement in noise levels near transportation facilities have occurred in the recent years, particularly because of an increase in traffic.
