Data indicating the level of noise according to the strategic noise mapping of consolidated sources (roads, railways, airports and industry) within areas with a population of at least 250,000 people (agglomerations). Lnight indicates night time annual average noise level results in dB, where night is defined as 2300 - 0700. This data is a product of the strategic noise mapping analysis undertaken to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC).

Data indicating the level of noise according to the strategic noise mapping of major rail sources within areas with a population of at least 100,000 people (agglomerations) and along Network Rail routes with more than 60,000 train passages per year. Lden indicates a 24 hour annual average noise level with separate weightings for the evening and night periods. This data is a product of the strategic noise mapping analysis undertaken to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC).

Data indicating the level of noise according to the strategic noise mapping of airport sources within areas with a population of at least 100,000 people (agglomerations) and airports with more than 50,000 (fifty thousand) air traffic movements per year. Lden indicates a 24 hour annual average noise level with separate weightings for the evening and night periods.This data is a product of the strategic noise mapping analysis undertaken to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC).

Noise Management Areas are required by the Environmental Noise Directive. The Noise Management Areas provide a framework for the local management of noise.

Lnight indicates night time annual average noise level results in dB, where night is defined as 2300 - 0700. This data is a product of the strategic noise mapping analysis undertaken to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC).

Data indicating the level of noise according to the strategic noise mapping of all road sources within areas with a population of at least 100,000 people (agglomerations). Lden indicates a 24 hour annual average noise level with separate weightings for the evening and night periods. This data is a product of the strategic noise mapping analysis undertaken to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC).

Areas considered to be urban (with a population greater than or equal to 100,000 people) where, under the Environmental Noise Directive (Round 2), Strategic Noise Mapping has been carried out. This data includes a 2km buffer.

Noise Management Areas are required by the Environmental Noise Directive. The Noise Management Areas provide a framework for the local management of noise.
