Industrial noise – Areas where limit values are exceeded, over 24 hours (Lden indicator)

Description

**Strategic Noise Map** **** Data produced by Impédance engineering on behalf of the metropolis Aix-Marseille Provence Industrial noise according to the Lden indicator for type C maps on the Aix-Marseille Provence Metropolis. Results of acoustic modelling calculations. Type C map locates areas where limit values are exceeded. The Lden indicator (for Level day-evening-night) represents the weighted average noise level during the day by giving a stronger weight to the noise produced in the evening (18-22h) (+ 5 dB(A)) and during the night (22h-6h) (+ 10 dB(A)) to take into account the increased sensitivity of individuals to noise pollution during these two periods.
