The noise maps on this site show estimated levels of road traffic and railway noise according to the strategic noise mapping within agglomerations and along major transport routes.
Noise levels were modeled 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 Defra in 2012 to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC) and the Environmental Noise (England) Regulations 2006 (as amended). Results are shown for three noise level indicators:
Noise Action Planning Important Areas (IAs) for roads and railways are also shown. These areas provide a framework for the local management of the Important Areas. For additional context the location of Air Quality Management Areas (AQMAs) can also be shown.
