METHOD AND DEVICE FOR ATTENUATING AERODYNAMICALLY INDUCED NOISES CAUSED BY VEHICLE GRILLE

摘要

A bumper for a front end of a vehicle includes a body having an opening defining an air flow inlet. The opening is elongated in the transverse direction of the body and is defined by spaced apart transverse walls and spaced apart side walls. A grille is disposed in the opening. The grille includes at least one generally horizontal member having at least one sound attenuating member attached thereto and configured to at least partially alter the air flow passing through the grille to mitigate resonance associated with the flow of air through the grill.
