ABSTRACT:
An air filter housing for an internal combustion engine, which includes an unfiltered air capsule and a filtered air capsule, contains an orifice with perforations which are covered by air-permeable fabric or a sound element. Airborne sound emission occurs through these orifices and through the fabric or the sound element in such a way as to optimize the exterior and interior sounds of the vehicle.
