Klankbord is a collaborative initiative by Dutch organizations including the RIVM, Stichting Hoormij, and Samen Meten, dedicated to mapping noise pollution and its impact on public health in the Netherlands. The organization operates the ‘Nationale Geluidmeetdag’ (National Noise Measurement Day) and provides the free Klankbord App, which allows citizens to conduct objective sound level measurements and subjective assessments of noise nuisance. By aggregating this crowdsourced data, Klankbord generates reports to raise awareness and inform policy regarding environmental noise exposure.
