Near the complex, insulation has already been installed in 170 residences and three schools, with 47 more being promised.

Additionally, six houses have been purchased by the airport operator through its Voluntary Dwelling Purchase Scheme (VDPS).

Daa claims it is willing to purchase additional homes from qualified homeowners who choose to sell, and it has already made this offer for 41 residences.

"Dublin Airport is a significant employer and economic contributor to the areas immediately surrounding the airport, and we're very conscious that our operations can have an impact on those living and going to school nearby," Gary McLean, the managing director of Dublin Airport, stated.

The updated statistics coincide with the launch of a new, free Maploom portal by the airport, which allows users to enter an Eircode to determine whether they qualify for any of the insulation or purchasing programs.

Dublin Airport will purchase residences in a certain region for more than 30% more than market value under the VDPS. 5 to 10 dB is the target noise reduction range for the Residential Noise Insulation Scheme.

There is also a school insulation scheme in place for the local pre-schools and schools.

As part of its proposal to alter the North Runway's operational hours, Daa has also suggested a new Residential Sound Insulation Grant Scheme, which would offer up to €20,000 for noise insulation to about 600 households.

An Bord Pleanála recently suggested, subject to certain restrictions, easing the limitations on planes throughout the night and expanding the North Runway's usage.

But Aer Lingus declared the plans impractical, and daa called them a step backward.

Because of the potential noise impact, many residents who live near the airport or under the flight path have opposed any extension of nighttime flight hours.

The airport's passenger limitation, which now limits the number of users to 32 million annually, is another issue that some locals are against lifting.
