Dutch health institute RIVM is launching a large, long-term study on the effect noise from traffic has on the development of children. The RIVM will follow thousands of kids and their development from pregnancy to adulthood, AD reports.

The study was launched based on the findings of research by the German University of Wuppertal. That study showed that 5-year-olds who live in areas with high levels of traffic noise, are three months behind in their development compared to kids who live away from traffic noise. This is caused by lack of sleep, which is caused by noise. The kids are particularly behind in motor skills, language and numeracy.

The RIVM study will focus on the long-term effects.
