摘要

The airborne noise reduction device has an air- and gas-carrying outer pipe (1) with an inner pipe piece (2) and a separation wall chamber (3). Lateral chamber walls are formed by the separation wall (4) between the outer pipe and the inner pipe piece, where a bridge forms a slot (7) with the outer pipe.
