Noise Round 4 Rail Agglomeration (Lnight)
Polygon dataset from Round 4 (2022) of strategic noise mapping for agglomeration railways in Ireland, representing conditions during 2021. It provides noise contours for the Lnight period, covering the Cork, Dublin and Limerick noise agglomerations. Each contour's dB value represents the annual average night-time noise level (Lnight) associated with railway traffic in these urban areas. The dataset is published by Ireland's Environmental Protection Agency as part of national obligations for environmental noise assessment, supporting spatial analysis of railway noise exposure near agglomerations.This is a polygon dataset of the strategic noise mapping of agglomeration railways for Round 4 (2022), representing the situation during 2021, in the form of noise contours for the Lnight period for Cork, Dublin and Limerick noise agglomerations. The dB value represents the annual average Lnight…
