The expert from Norway gave a presentation (GRB-55-07), showing the study results of the TNO report commissioned by the European Commission on vehicle noise limit values, performed by the project group of noise of the conference of European directors of roads (CEDR). As a conclusion of this study, CEDR suggested more stringent noise limits for new vehicles. The study received several comments. The expert of OICA argued that consumer costs on further noise abatement are compared to industry costs for measures on vehicles noise reduction and the expert from EC suggested considering not only economical aspects but on a broader basis.
