摘要

The device has an air filter (3) with housing (4). An air duct (6) is provided in an area within which highest acoustic pressure is present in proximity to resonant frequency of the air duct which is locked with a noise absorbing material (13). An opening (12) is arranged in center between an inlet opening that is present outside of the housing and an outlet opening of the air duct. An independent claim is also included for a motor vehicle.
