The limits that are now in operation for new cars, buses and trucks you can find here. Although the limits have been lowered between 7 and 10 dB, the effect on the noise levels in every day practice has been somewhat disappointing. What is worse, the amount of traffic has increased much more rapidly then the modest decrease in noise emission could cope with. The result is a net increase in traffic noise, adding considerably to the adverse effects on the population.
Noise emission apparently is not the first thing people look at if they buy cars. But, all other things being equal, wouldn't you rather buy a quiet one? Less noise might mean better and more durable construction, so you could be better of after all. If you or your company are to buy a new car or van, look first at our database of noise emission levels. In the database only the cars and trucks are listed which are at least 4 dB(A) (cars) or 2 dB(A) (trucks, vans) more silent then the standards require. If your car or truck is not in the list, it simply means that it is close to the standard.
