Noise Round 4 Road National (Lden)
This dataset provides polygon-based noise contours from Round 4 strategic noise mapping (2022) of major roads in Ireland, representing conditions during 2021. It covers the Lden indicator (day, evening, night weighted average noise level) for the Cork, Dublin and Limerick noise agglomerations, as well as major roads outside these agglomerations. The data is published by the Environmental Protection Agency and forms part of Ireland's obligations under environmental noise mapping requirements, supporting assessment of road traffic noise exposure at a national level.This is a polygon dataset of the strategic noise mapping of major 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 and the major roads outside of the noise agg…
