Description
Indicates noise levels induced by road transport Mapping represents isophone curves plotted in increments of 5dB(A) from 55dB(A) The Lden (Day Evening Night for Day Evening and Night) is the indicator of the average noise level for the whole day of 24h. It is calculated by calculating over the year the noises recorded at the different periods of the day, to which a weighting is applied for the more sensitive periods (+5dB(A) in the evening and +10 dB(A) at night). It is therefore not a real or measured noise level, but a weighted indication. The entry was made for a cartographic restitution scale of 1/10,000th. The cards will be updated every 5 years.
