Noise Round 4 Road Agglomeration (Lden)
This dataset provides polygon-based strategic noise mapping for agglomeration roads in Ireland, produced for Round 4 (2022) and reflecting conditions during 2021. It presents noise contours for the Lden indicator (day-evening-night average) covering the Cork, Dublin and Limerick noise agglomerations. Each polygon's dB value represents the annual average noise level attributable to road traffic within these urban areas. The data is published by the Environmental Protection Agency (Ireland) as part of national strategic noise mapping obligations, supporting assessment of environmental noise exposure from road transport in major Irish cities.This is a polygon dataset of the strategic noise mapping of agglomeration roads for Round 4 (2022), representing the situation during 2021, in the form of noise contours for the Lden (day, evening, night) period for Cork, Dublin and Limerick noise agglomerations. The dB value represents the annua…
