What can cities do to reduce traffic noise
Traffic noise is a major source of environmental pollution in Europe, affecting the health and quality of life of millions of people. Noise levels vary across countries, depending on their regulations and standards. There are ways to reduce traffic noise, such as using quieter vehicles, enforcing noise limits with sound sensors and monitoring noise levels with smart devices. People who live in noisy areas can also protect themselves by using a sound camera to find and seal air leaks in their homes.
