Environmental Noise Directive

sound waves

This Directive requires us to produce noise maps for major roads and railways in Wales, and for transportation and major industry within the largest Welsh towns and cities.

The Directive also requires us to produce action plans based on the noise maps and say what we will do about transportation and industrial noise in the noise-mapped areas.

The noise maps for Wales are based on calculation rather than measurement. They should only be considered a starting point for identifying areas that need priority action. You can find out more about the maps by going to the “Second round noise mapping” and “Third round noise mapping” pages.

We and the other organisations responsible for managing noise in Wales have decided to produce a single plan for the whole of Wales. It covers all of the major forms of man-made noise, including neighbourhood noise.
