Several studies have found that noise pollution is a real public health problem, causing severe effects on concentration, sleep and stress in population. The Environmental Noise Directive 2002/49/EC and the CNOSSOS-EU framework are the main European instruments to address noise pollution, requiring Member States to publish noise maps and noise management plans every five years. DYNAMAP is a LIFE+ project aimed at developing a dynamic noise mapping system to represent the acoustic impact of road infrastructures in real-time using a low-cost wireless acoustic sensor network, including the automatic detection and removal of acoustic events unrelated to traffic noise.
