To understand the noise impact on the local community, the Dublin Airport has 25 fixed and two mobile noise monitors deployed in the local area, generally under or near flight paths. The monitors detect and send the noise levels to a central system every second, 24 hours a day, seven days a week.

A ‘noise event’ is created when the monitor detects noise exceeding the background or local noise level for an appreciable amount of time. This could be due to any number of factors, be it barking dogs, cars or an aircraft. By continuously monitoring the noise level and integrating data from Air Traffic Control (ATC), our systems can determine if the noise event was generated by an aircraft, or another source.

The data collected by the monitors is presented in the following dashboard, which you can access and use by initially selecting a monitoring location in the top left. This will update all of the data for that monitoring location and will display the number of arrivals and departures detected at that location shown at the top. Additional analytics available at the bottom show:

• The location of the monitor.
• The breakdown of flights per hour and per day.
• Detailed information on the collected noise data, including the distribution of peak noise events, if these were caused by arrivals or departures operating from specific runways and how these events were spread throughout the day.

The dashboard is automatically updated every month and you can access data from previous months using the drop-down.

For almost live noise readings measured by our noise monitors can be found on WebTrak. By visiting this site, you can track aircraft arriving and departing from Dublin Airport and view the noise readings measured from the noise monitors. 

Noise and Flight Track Monitoring reports are published quarterly. These reports detail the monitored locations and measurement results both in time-averaged and single event noise metrics. The report aims to provide a comprehensive guide and understanding of noise levels regarding noise mitigation and management strategies. To view these reports, click here.
