Dataset description

The European Directive on Strategic Noise Maps requires at least the representation of global 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 in this dataset are related to Lden indicator. “Lden” is an indicator of the overall noise level during a day (day, evening and night) used to qualify the discomfort related to noise; exposure to noise. It is calculated from the indicators “Lday”, “Levening”, “Lnight”, averaged noise levels over the periods 6h-18h, 18h-22h and 22h-6h. It is more precisely the isophone curves plotted by step of 5 dB(A) starting at 55 dB(A) over a whole day. The data concerns Palissy Boulevard, Rue de la Marne and Réole Street in Parhenay. Articles L572-1 to 11 of the Code de l' Environment laying down various provisions of; adaptation to Community law in the field of the Environment and the texts of #x27; Applications (Decree No 2006-361 of 24 March 2006, Decree of 4 April 2006 and Circular of 7 June 2007 on the issue of noise maps and noise prevention plans in the field of environment) provide for the indicators, methods of calculation to be used and results I'm waiting. The data for this lot have been collected in accordance with these texts. __Origin__ The noise levels emitted by a given infrastructure during an average day are evaluated using numerical models producing isophone curves translated into noise zones, according to the; index recommended for all modes of transport at European level, namely the Lden index and l' index Ln.The isophone curves, described by the resource N_BRUIT_ISOPHONE_L thus serve to delimit the external borders and, where appropriate, internal noise zones by range of #x27; indices. __Partner organisations__ DDT Deux-Sèvres __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-3453a4b0-d7e9-4fc8-98c2-624f7d90094a) * [COVADIS data standard: Table describing Noise Areas of (to be completed)(http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_BRUIT_ZBR_INFRA_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/9afd21c4659ec21dc28df14e82f2d285c5a88ff5)
