Noise Round 4 Airport Agglomeration (Lden)
This dataset provides polygon geospatial data from Round 4 (2022) of Ireland's strategic noise mapping programme, representing airport noise conditions during 2021 within agglomeration areas. It presents noise contours for the Lden indicator, a day-evening-night weighted annual average noise level expressed in decibels, used to assess long-term environmental noise exposure around airports. The data is published by Ireland's Environmental Protection Agency as part of national obligations for strategic noise mapping. It supports analysis of noise pollution levels near airport agglomerations and can be used for environmental assessment, spatial planning, and noise exposure monitoring purposes.This is a polygon dataset of the strategic noise mapping of agglomeration airports for Round 4 (2022), representing the situation during 2021, in the form of noise contours for the Lden (day, evening, night) period. The dB value represents the annual average Lden indicator value in decibels over…
