Noise map 2022, roadTrainFlights 2 m Leq 24h

The map layer displays the calculated equivalent sound level, averaged over 24 hours and includes all noise sources including background levels. All noise sources refer to noise from road traffic on the state and municipal road network, air traffic, noise from the railway lines, metro, Tvärbanan, Roslagsbanan and other railways. Input data is based on actual recorded traffic flows in 2019 as well as model-calculated data for road sections where no measurement is available. Reported sound levels should be seen as an indicative value for the location. Provided by environmental management.
