Acoucité works in partnership with Greater Lyon to produce noise maps according to the Directive 2002/49/EC of the European Parliament and of the Council of 25 June 2002 relating to the assessment and management of environmental noise.
These maps are available on the Greater Lyon website (in French).
According to the Directive, noise maps must be updated every 5 years . The current noise maps were produced in 2007 and in 2012.
