Abstract
In 2013 or early 2014 the European Union will decide upon a new “Regulation on the sound level of motor vehicles”. It will specify a new type approval test method for noise emission and will give revised limit values for the permissible noise emission per vehicle (sub- category. The new regulation may be seen as a final stage of a long series of developments towards a more representative way of testing, but at the same time it should be a starting phase of regular reductions of limit values in future in order to achieve a substantial reduction of traffic noise impact and improvement of urban environmental conditions. In this paper the historical development of noise emission test methods, the shortcomings of the current test method and the expected improvements resulting from the new test method are discussed. The possible effects of three alternative proposals for the revision of the limit values and an outlook to future developments concerning vehicle noise emission test methods are presented.
