Noise Map Viewers

Extrium recently helped Defra and Welsh Government produce and publish strategic noise map results and noise action plan information in England and Wales. Using this data, Extrium has developed noise map viewers for both England and Wales.

The viewers show noise levels for roads and railways,
locations identified for noise action planning as well as
air quality management areas (AQMAs). For Wales the
viewer also shows industrial noise levels and the
locations of quiet areas.
