Abstract : There is an increasing tendency of tightened up legal prescriptions for noise reduction in order to improve the steadily deteriorating quality of life. Vehicles are the most important noise sources in the street traffic. To decrease their influence, lower limiting values for the external noise of vehicles are aimed at. In the second half of the eighties the external noise of utility cars in Europe will be limited to 80 dB(A). These limits are low and will not without difficulties be achieved in all motor-vehicles, especially not in utility cars (lorries and buses, but terrain-vehicles as well). This is not only a result of the situation in the driving aggregate, the combustion engine, but in other direct and indirect noise sources too.
