ICAN Acoustics provide comprehensive noise studies for all existing and proposed developments, ranging from single buildings to major factories/facilities and road/rail infrastructure. We provide environmental noise assessment services for EPA licensed sites which are normally assessed using NG4 guidance issued by the Irish Environmental Protection Agency (EPA).
In January 2016, the Environmental Protection Agency (EPA) in Ireland revised its published Guidance Note for Noise: Licence Applications, Surveys and Assessments in Relation to Scheduled Activities (NG4). This document supersedes the following Agency publications, which are withdrawn with immediate effect. The NG4 guidance note was originally published in 2012, and this current update to NG4 was published in 2016.
January 2016, NG4 guidance provides additional information and clarifications on a number of items:
EPA Licensed sites are typically required to operate within the following noise limiting levels.
- Day: 07:00-19:00, 55 dB(A) LAr,T
- Evening: 19:00-23:00, 50 dB(A) LAr,T
- Night: 23:00-07:00, 45 dB(A) LAeq,T
