Cars, trains, planes: For two thirds of the European population, traffic noise is part of everyday life. However, the right environment can have a major impact on this nuisance, as Empa researchers have found out. Green spaces in urban areas help to make road and railroad noise less of a nuisance. Only in the case of aircraft noise does this seem counterproductive: the greener the surroundings, the more disturbing the aircraft noise.

Pilot assistance system LNAS reduces noise in the approach path

June 22, 2020 sarah JonasResearch Results

During more than 90 approaches to Zurich Airport conducted under the leadership of the Swiss SkyLab Foundation, researchers from Empa and the German Aerospace Center (DLR) tested an assistance system that supports pilots via a display during quiet and, at the same time, fuel-efficient approaches. The results show a measurable reduction in noise emissions and fuel consumption. Now the system, developed by DLR, is to be made ready for production.
