摘要

The air duct (1) for motor vehicles has a duct wall with a first (3.1) section and at least one second (3.2) section. The first duct wall section is formed at least partially by a lining element (4), and the second duct wall section is formed at least partially by body element (5). The first duct wall section is connected and sealed in relation to the second section in the circumferential direction with regard to the flow longitudinal axis. The first and/or second duct wall section on their respective inner sides have at least one acoustically active layer (6).
