Noise Round 4 Airport National (Lden)
This national geospatial dataset presents Round 4 (2022) strategic noise mapping for major airports in Ireland, reflecting conditions during 2021. It provides noise contour polygons for the Lden indicator, which measures average day, evening, and night noise levels. Major airports are those identified under the relevant regulations as exceeding specified movement or size thresholds requiring noise mapping. The dataset is published by Ireland's Environmental Protection Agency and supports assessment of environmental noise exposure around major airport facilities as part of the country's strategic noise mapping obligations.This is a polygon dataset of the strategic noise mapping of major airports for Round 4 (2022), representing the situation during 2021, in the form of noise contours for the Lden (day, evening, night) period. Major airports were identified under the Regulaitons as those airports exceeding the thr…
