August 2026 - Lden, the EU's day-evening-night noise level
Singapore Changi Airport serves Singapore. In August 2026, the aircraft noise of an average day around it reached an Lden of 55 dB or more - the lowest level the EU's noise maps report - over 144 km², and 65 dB or more over 15 km². Night flights (23-07 local time) made 69% of that noise as Lden counts it, each night flight like ten daytime ones.

How it is calculated
From the positions of the flights the OpenSky Network receives over ADS-B, with the engine thrust each part of a flight needs and the noise curves of ECAC Doc 29, the method behind the EU's official noise maps (details). The areas count the places within 35 km of the airport that are nearer to it than to any other airport with a runway of 1.5 km or more. Where OpenSky's receivers miss flights, the levels come out too low.
