Documents ‘Concept of QRTV GTR based on R.E.3’ and ‘Perception and evaluation of Vehicle exterior noise by pedestrian in different traffic situations and different operating conditions’ were named to show potential neutral or negative impact of stationary sound, whereas WBU mentioned that numerous examples would prove the opposite. It became clear that also here further studies are necessary to come to a clear view. The chairman however pointed out that all participants must be ready to accept the conclusion of those studies, once the content is agreed upon. Germany proposed to determine a deadline of end 2017 for a revised proposal to GRB of the QRTV Regulation to come. The mandate of the IWG must be extended accordingly.
