      <gmd:abstract>
        <gco:CharacterString>Ce jeu de données localise les secteurs exposés à des niveaux sonores issus du bruit des grands axes ferroviaires selon l’indice Lden pour l’année 2007 en France.

L’indice Lden est un des deux indicateurs préconisés par la directive européenne 2002/49/CE, relative à l'évaluation et à la gestion du bruit dans l'environnement, afin de mesurer le niveau sonore décrivant le bruit dans l'environnement. Au sens de la Directive, ce dernier est émis par les moyens de transports, le trafic routier, ferroviaire ou aérien ou provient de sites d'activité industrielle. 

L’indice Lden signifie « Level Day - Evening – Night ». Il s’agit donc d’un indicateur du niveau de bruit global pendant 24 h (jour, soir et nuit) utilisé pour qualifier la gêne liée à l'exposition au bruit. Il est calculé à partir des indicateurs « Lday », « Levening », « Lnight », niveaux sonores moyennés sur les périodes 7h-19h, 19h-23h et 23h-7h. 

Il est exprimé en décibel A (dB(A)), qui est l’unité retenue pour représenter les sensibilités de l’oreille humaine. 

Dans le calcul de Lden, les indicateurs « Levening » et « Lnight » sont pondérés pour tenir compte du fait, qu’à niveau égal, nous sommes plus sensibles au bruit au cours de ces périodes : - +5 dBA à la période de la soirée, ce qui signifie qu’un véhicule circulant en soirée est considéré comme équivalent presque trois véhicules circulant le jour ; - +10 dBA à la période de nuit, ce qui signifie qu’un véhicule circulant en soirée est considéré comme équivalent presque dix véhicules circulant le jour. L’indicateur est moyenné sur une année civile.</gco:CharacterString>
