The noise maps on this site show estimated levels of road traffic, railway and industrial noise according to the strategic noise mapping within agglomerations and along major transport routes.
Noise levels were modelled on a 10 m grid at a receptor height of 4 m above ground. This data is a product of the strategic noise mapping exercise undertaken by the Welsh Government in 2012 to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC) and the Environmental Noise (Wales) Regulations 2006 (as amended). Results are shown for all noise level indicators set out in Regulations:
The noise action plan for Wales has identified Quiet Areas and Priority Areas (for roads and railways). These areas provide a framework for the local management of noise and can be displayed. For additional context the location of Air Quality Management Areas (AQMAs) can also be shown.
