APIJoinable5/7Query nowOpen workbench Subscribe🇫🇷France

This dataset provides aircraft noise levels according to the Lden indicator (Level day-evening-night) for type A noise maps covering the Aix-Marseille-Provence Metropolitan area. Type A maps identify zones exposed to noise, with Lden representing a weighted average noise level over a 24-hour period, giving extra weight to evening and night-time periods. The dataset is published by Métropole Aix-Marseille-Provence and is useful for environmental and urban planning assessments related to aircraft noise exposure.Bruit aérien selon l'indicateur Lden pour les cartes de type A sur la Métropole Aix-Marseille Provence. La carte de type A localise les zones exposées au bruit. L’indicateur Lden (pour Level day-evening-night) représente le niveau de bruit moyen pondéré au cours de la journée en donnant un poids...
