Beschreibung
Zusammenfassung:	The invention relates to a rotor blade (20) for a wind turbine (10) with a noise reducing device (30) at the trailing edge section (23) of the rotor blade (20), wherein the noise reducing device (30) comprises at least a first opening (31) such that the airflow from the leading edge section (24) of the rotor blade (20) to the trailing edge section (23) of the rotor blade (20) is partially diverted through the first opening (31). Thus, noise which is generated at the trailing edge (231) of the rotor blade (20) is reduced. Furthermore, the invention relates to a wind turbine (10) comprising at least one such rotor blade (20).
