Noise Round 4 Road Agglomeration (Lnight)
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 Lnight period for Cork, Dublin and Limerick noise agglomerations.
The dB value represents the annual average Lnight indicator value in decibels over the night time.
The strategic noise mapping of agglomeration roads includes all roads within the three noise agglomeraiton areas.
The values are calculated at a height of 4.0m above local terrain, not measured, and should be treated with caution when looking at specific locations.
The strategic noise mapping of agglomeration roads was undertaken by Noise Consultants Limited inside the three noise agglomerations, under contract to the agglomeration local authorities, with support from Transport Infrastructure Ireland (TII).
The outputs of the Round 4 noise mapping exercise were generated using a new common noise assessment method for Europe (CNOSSOS-EU), as set out in the revised Annex II of Directive 2002/49/EC, and they are not directly comparable to any strategic noise maps previously generated under Rounds 1 to 3, as these revised methods calculate noise emissions, propagation and residential population exposure differently from the methods used in previous rounds.
The noise maps are the product of assimilating a collection of digital datasets, and over the last 15 years there have been ongoing significant improvements to the quality of the digital datasets describing the natural and built environment in Ireland, therefore the Round 4 strategic noise mapping includes changes to the model input datasets being used, compared to previous rounds, particularly related to the road network modelled, the terrain model, building heights, traffic flows and ground cover.
The strategic noise maps should not be relied upon in the context of planning applications for noise sensitive developments in the vicinity of the mapped sources.

- Purpose
-
Strategic noise maps are to be made every 5 years by noise mapping bodies designated under the European Communities (Environmental Noise) Regulations, SI 549 of 2018, which transposed EC Directive 2002/49/EC into Irish legislation.
These strategic noise maps were prepared for Round 4 (2022), representing the annual average situation during 2021.
The strategic noise maps are to be used to identify priorities (Important Areas and Priority Important Areas) for noise action plans, which are to be made or revised every 5 years by designated action planning authorities, namely Local Authorities. They can also be used to identify potential Quiet areas in the three noise agglomerations.
The strategic noise maps should not be relied upon in the context of planning applications for noise sensitive developments in the vicinity of the mapped sources.

The strategic noise maps are to be used to identify priorities for noise action plans, which are to be made or revised every 5 years by designated action planning authorities, namely Local Authorities. They can also be used to identify potential Quiet areas in the three noise agglomerations.
This is a polygon dataset of the strategic noise mapping of agglomeration roads, in the form of noise contours for the Lnight period for Cork, Dublin and Limerick noise agglomerations.
The contour polygons are derived by interpolation from calculated points on a regular 10m spacing located outside building footprints. Calculations were undertaken using Predictor-LimA software in line with the methodology in the consolidated Annex II of Directive 2002/49/EC as of 28 July 2022.
The strategic noise mapping of agglomeration roads includes all roads within the three noise agglomeraiton areas.
The dB value represents the annual average Lnight indicator value in decibels over the nght time.
The values are calculated at a height of 4.0m above local terrain, not measured, and should be treated with caution when looking at specific locations.
