For the acoustic mapping, the calculation algorithms recommended by the European Community were utilised, with reference to Directive 2015/996/EU of 19 May 2015, which establishes common methods for determining noise, pursuant to the Directive 2002/49/EC of the European Parliament and of the Council, entered into force on 1 January 2020.  The acoustic simulations therefore are implemented using the common methods for noise assessment in the European Union (standard calculation “CNOSSOS-EU”), for the following components: road noise: CNOSSOS-EU Road 2015.
