How this atlas is made · What “last verified” means · What “source-checked” means · The full record behind this page

Dublin has logged ambient sound at 14 sites since 2009 and publishes it live. When the network showed a four-decibel rise, no reading could trigger anything: no legal limit exists.

Dublin City Council began installing a permanent ambient sound monitoring network in 2009 and had eleven locations running by 2010; it now reports monitoring stations at 14 sites across the city. The monitors log sound continuously in five-minute periods and are deliberately kept away from kerbside traffic, so that no single source dominates. Sonitus Systems manufactures the hardware and maintains the network; the readings have been public online since at least 2016, on a joint air-and-noise portal since 2020, and through an open API under a CC BY 4.0 licence.

Live 📅 since 2009

📊 Impact

The readings trigger nothing. The council's own 2010 report notes there are no legally binding statutory limits for ambient sound levels, so the data serve as guidance, as a check on the strategic noise maps and as input to plans for reducing noise exposure. When the network showed average ambient levels rising four decibels between 2012 and 2018 — daytime from 57 to 61 decibels, night-time from 52 to 56 — the council's noise official attributed part of the rise to weather and said most sites had been reasonably consistent over five years.

🎓 Lesson

A network sited so that no one source dominates is built to describe a city's overall soundscape, not to single out a culprit. Dublin's answers to rising levels — low-noise stone mastic asphalt on 41 percent of the council's 2018 resurfacing, and a sound assessment that found no decibel reduction when speeds fell from 50 to 30 km/h — came through the noise action plan and separate studies. Where no legal limit exists, an ambient network is an instrument of reporting, not enforcement.

What the mapping says
None of the council's sources describes a threshold that sets off any action. The 2010 report states there are no statutory limits for ambient sound; the portal says the information 'is used to generate plans for reducing noise exposure and for making better environmental policy decisions'; and the council's noise official told councillors the monitors track 'the on-going, ambient mix of sound', not nuisance noise.
Caveat
This describes the monitoring network; noise nuisance complaints are handled through a separate council process.
