Abstract
Rolling noise, due to the tyre-pavement dynamical contact, is the main contribute to traffic noise when vehicle speed is higher than 100 Km/h. Actually rolling noise reduction methods are particular tyre engraving shape and absorbing pavements. In this paper alternative active methods for rolling noise reduction are proposed and compared. Such a methods have been applied by realizing original prototypes which work on steady conditions with a previous recorded rolling noise. A future prototype is also proposed which is a dynamical system the working conditions of which are very close to the effective ones.File in questo prodotto:
