Pour les cartes de type A (CBSTYPE), chaque zone de bruit est généralement délimitée par 2 courbes isophones (Lden 55-60, 60-65, 65-70, 70-75 et Ln 50-55, 55-60, 60-65, 65-70) ou par la courbe isophone de limite inférieure (Lden &gt;75, Ln &gt; 70).
Pour les cartes de type C (CBSTYPE), chaque zone de bruit est délimitée par la courbe isophone de limite inférieure (Lden &gt; 68 ou 73, Ln &gt; 62 ou 65).

            <gco:CharacterString xmlns:gco="http://www.isotc211.org/2005/gco">Les niveaux de bruit émis par une infrastructure donnée au cours d’une journée moyenne sont évalués au moyen de modèles numériques produisant des courbes isophones traduites en zones de bruit, selon l’indice recommandé pour tous les modes de transport au niveau européen, à savoir l’indice Lden et l’indice Ln.
Les courbes isophones, décrites par la ressource N_BRUIT_ISOPHONE_L servent ainsi à délimiter les frontières externes et le cas échéant internes des zones de bruit par plages d’indices.

Sources des données :
Zones de bruit par source de bruit et par indice acoustique, délimitées par des courbes isophones décrites par la ressource N_BRUIT_ISOPHONE_L pour une année de référence donnée.
Ces zones de bruit sont le résultat de la modélisation acoustique par le logiciel NoiseModelling, développé en partenariat entre le Cerema et l’UGE-CNRS, et de données d’entrée issues de la base PlaMADE établie par le Cerema.
