Table describing the Noise Zones of the major land transport infrastructure of the Gard department (Type C LN night)
Description
Noise level zones describe a noise exposure situation based on a noise indicator or area affected by noise. They are used primarily for the preparation of strategic noise maps pursuant to Article R.572-5 of the Environmental Code.
Noise zones are geometric elements of the strategic noise map.
For type A maps (CBSTYPE), each noise zone is usually bounded by 2 isophone curves (Lden 55-60, 60-65, 65-70, 70-75 and Ln 50-55, 55-60, 60-65, 65-70) or shares the lower limit isophone curve (Lden >75, Ln > 70).
The type B map locates the sectors affected by noise, defined by the noise classification of land transport infrastructure.
For type C maps (CBSTYPE), each noise zone shall be bounded by the lower limit isophone curve (Lden > 68 or 73, Ln > 62 or 65).
