Loud motorcycles and cars becoming annoying
Even compliant new vehicles prove to be much too loud in practical tests
The only recently revised international noise approval regulations for motor vehicles are not suitable for preventing extreme noise emissions in road traffic. This is according to a recent study for the German Environment Agency (UBA). Various brand-new motorcycles and sports cars that complied with the approval regulations were 20 dB or more louder during measurements outside the type test area of the approval than during the operating condition that is decisive for the type test. UBA's President Dirk Messner said: "Manufacturers of motorcycles and cars must be made responsible for making their vehicles as quiet as the state of the art allows. Unnecessary noise ex works is unacceptable on the road and is a strain on the health and nerves of everyone".
