Acoustics

Noise measuring system

Isavia has taken various measures to mitigate noise from flights at Keflavík Airport. One such measure was to set up a noise-measuring system in 2017 to monitor which flights cause the most noise and react accordingly.

Three fixed acoustic sound-level meters and one mobile sound-level acoustic meter are located in the  vicinity of Keflavík Airport. These meters form a system enabling residents, stakeholders and Isavia to monitor flights and noise measurements and report nuisances caused by flight traffic movements. A link to the noise-measuring system can be found on the Isavia website.

Work was carried out on preparing an action plan against noise in 2019 in co-operation with Reykjanesbær and Vegagerðin (the Icelandic Roads Administration). This work fulfils Regulation No. 1000/2005 on mapping and action plans. The plan extends to 2030 and underwent a presentational process wherein comments were welcomed. The plan can be accessed on the  "Website of Reykjanesbær". Last year, Isavia received 34 reports of noise and nuisance caused by air traffic at Keflavík Airport, most of which were linked to passenger flights directly over residential areas early in the morning. 

Continuous efforts are spent on monitoring noise measurements and ensuring that the rules of the airport as regards runway use and flights over residential areas are complied with.

The two pictures below show the comparison between flight routes 2017 and 2018. The pictures are drawn from heat maps and show well the change in air traffic over residential area at Reykjanes. Now considerable smaller part of the residential area is under direct air traffic.

In 2017, Isavia hired the engineering firm Efla to produce a sound map for the airport. This map was released in early 2018 and shows calculated 24-hour noise levels around Keflavík Airport. According to Efla’s mapping, there is no resident that suffers noise caused by air traffic which exceeds 64 dB but around 300 that are exposed to noise levels between 60–64 dB and 1,300 who are exposed to noise levels of 55–59 dB.

In spring 2018, new flight profiles for Keflavík Airport were adopted. These profiles were designed with the aim of minimising noise and nuisance caused by flight traffic at the airport. When organising air traffic, Keflavík Airport strives to use those runways which cause the least nuisance for residents in the vicinity of the airport. Every effort is made to implement this, with due regard to safety and environmental factors, such as wind and runway conditions.

There were five reports of nuisances caused by flight movements at Reykjavík Airports in 2019, mainly due to the traffic of training flights.
