Sound classification of category 3 railway tracks — Isère

The purpose of the noise classification is to inform future residents of noise pollution related to land transport infrastructure and oblige them to implement the necessary protections in order to respect regulatory noise levels within sensitive buildings (housing, health, social, education, hotel): 35db(decibel)[A] on the day and 30db[A] at night. Classification makes it possible not to recreate a black dot of the noise. Preventive action is the only enforceable regulation concerning noise in land transport infrastructure. The sound classification has 5 categories classified from 1 to 5, with category 1 being the loudest. Are classified: roads flowing more than 5000 vehicles/day, railways of more than 50 trains per day and public transport on a clean site.
