Listen to the city with Securaxis SONAL™. A cost effective solution to improve cities operations and sustainability while respecting citizen’s privacy. Cities around the world are leveraging smart technologies to preserve and improve the quality of citizens’ life and the environment. Cities are growing and cities are getting louder with health and economic impacts. 80% of noise pollution in a city originates from road traffic. Combining AI and acoustic, we monitor noise (Db and frequencies) in real time, detect and count vehicles, classify them, indicate the speed and flow of traffic. For application such as the noise radar, road traffic noise mapping for infrastructure &urban planning and for road predictive maintenance, traffic monitoring or dynamic lighting. To listen to the sound of a city is to hear a living city, to hear its moments of strength and weakness.
