The European Directive on Strategic Noise Maps requires as a minimum the representation of the overall noise indicators Lden and Ln, for each source. These indicators correspond to the incident noise on the facades. The indicators represented are expressed in dB(A) and reflect a notion of overall discomfort or health risk. The data represents areas exposed to land transport infrastructure noise at night (Ln) using isophone curves drawn in steps of 5 dB(A) starting at 50 dB(A). The routes concerned is RD 950 going to Saintes on the commune of Melle. The Ln is the average sound level that isolates the night period (22h-6h).
