Launch of the noise radar experiment in Nice, France on January 14, 2022. Nice has volunteered with the Bruit Mission by the Ministry of Ecological Transition to experiment with an automated radar to control and sanction vehicle sound levels in circulation exceeding the authorized thresholds. The educational noise radars have made it possible to reduce noise pollution peaks by 30% between July and December 2021. Photo by Lucie Choquet/ABACAPRESS.COM
