Zusammenfassung:Arrangement for reducing aerodynamic noise on a slat (1) of a commercial airplane comprises a separating surface arranged on the lower edge (4) of the slat at the start of a concave profile curve (3) and/or on the upper edge (5) of the slat at the end of the concave profile curve. The separating surface consists of several brush hairs (7) distributed over the slat span and arranged at least in one row. Preferred Features: The separating surface is arranged on a support element extending along the slat span and movably fixed so that it can be adjusted on the lower edge of the slat at the start of the concave profile curve and/or on the upper edge of the slat at the end of the concave profile curve.
