Vehicle with sound absorber to reduce noise of tyres on road uses at least one hollow cavity provided in bodywork as resonator volume for sound absorber

摘要

At least one hollow cavity (2) provided in the bodywork is used at least in part as a resonator volume for a sound absorber or for holding the resonator volume of a separate sound absorber where the resonator volume is connected through a resonator neck (8) to the surroundings around the vehicle. The cavity can be provided in the vehicle door or in a side sill and connected to the ambient surroundings through the rain drain hole.
