24. The expert from EC informed GRB about the EU activities that aim to prevent or reduce the effects of exposure to environmental noise harmful for health (GRB-66-18). According to the expert, this work is conducted in the framework of Directive 2002/49/EC which inter alia provides for a road vehicle (acoustic) classification and a road surface (acoustic) classification. To allow detailed discussions with member States and stakeholders on environmental noise policy issues, the EU Noise Expert Group (NEG) had been established. The expert wondered if there was space for exchange of information between GRB and NEG. The Chair was of the view that GRB and NEG should identify common elements for future cooperation.
