Noise zone of a strategic noise map of type C, associated index Ln, on the road network of Upper Corsica

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 C maps (CBSTYPE), each noise zone shall be bounded by the lower limit isophone curve (Lden > 68 or 73, Ln > 62 or 65).
