Noise Round 4 Industry Agglomeration (Lden)
This API provides a polygon dataset from Ireland's Round 4 (2022) strategic noise mapping of industrial agglomerations, reflecting conditions during 2021. It presents noise contours for the Lden indicator, which represents the annual average day-evening-night noise level in decibels over a 24-hour period. The dataset is published by the Environmental Protection Agency and is used to assess and visualise environmental noise exposure from industrial sources within agglomeration areas across Ireland, supporting national noise mapping and monitoring obligations.This is a polygon dataset of the strategic noise mapping of agglomeration industry for Round 4 (2022), representing the situation during 2021, in the form of noise contours for the Lden (day and evening) period. The dB value represents the annual average Lden indicator value in decibels over 24…
