The Environmental Noise Directive 2002/49/EC requires the 28 Member State countries to map environmental noise following the newly adopted common noise assessment method CNOSSOS-EU. Regarding to the strategic noise mapping of road traffic noise, in the short term is was desired to enable conversion of existing datasets, associated with the current national or Interim Methods, to be utilised to help implement these new methods, instead of it being necessary to acquire new datasets. Following recent work commissioned by the European Commission, database look-up tables were developed to provide support to MS migrating from existing methods to CNOSSOS-EU, these conversion methodologies will be presented and explained. Some examples will be given on how existing data can be converted, along with any significant limitations to this approach, and methodologies for the capture of new datasets will be discussed, for situations where it is considered appropriate for the purposes of the competent authority.
