- The acceleration process on which the noise measuring method for the homologation test is based yields extremely high acceleration values associated with enhanced tyre-road noise contributions, which are not mirrored under real driving conditions. Measures taken by tyre manufacturers to reduce tyre-road noise in these atypical operating modes do not necessarily lead to a reduction of tyre-road noise in real traffic.The German Federal Environmental Agency (UBA) has commissioned extensive studies of driving behaviour in cars and commercial vehicles under real traffic conditions in order to evolve a concept for an improved noise measuring method, whose guiding principles and structure are presented
