Aircraft Noise Map (Ln)Carte du bruit aérien (LN)
Carte du bruit aérien (LN)Aircraft Noise Map (Ln)
API providing a map of the aircraft noise environment (in dB(A)) calculated for nighttime exposure around Toulouse Métropole, France. The Ln (Level night) indicator represents the average noise level during the night. Published via the Toulouse Métropole open data portal, this dataset is useful for assessing nighttime aircraft noise pollution and its geographic distribution across the metropolitan area, supporting environmental and urban planning analysis.Carte de l'environnement sonore aérien (en dB(A)) calculée pour une exposition nocturne. Ln (Level night) correspond au bruit moyen au cours de la nuit.
