What have some cities done about noise?
City dwellers hear traffic, building work and music almost without a break, and scientists now believe that constant noise can harm health. Studies show that people living near busy roads are more likely to suffer from high blood pressure and poor sleep. Children who attend noisy schools often do worse in reading tests. Some cities have responded by building quiet zones and by using road surfaces that make less sound. Individuals can help as well, for example by using headphones at a lower volume. Experts stress that noise is not simply an annoyance; it is a health problem that deserves the same attention as air pollution.
