A rotor blade assembly (100) and a method for reducing the noise ofa rotor blade (16) for a wind turbine (10) are disciosed. The rotor blade (16) has surfaces defining a pressure side (22), a suction side (24), a leading edge (26), and a trailing edge (28) extending between a tip (32) and a root (34). The rotor blade assembly (100) further ineludes a noise reducer (110) configured on a surface of the rotor blade (16), the noise reducer (110) inciuding a plurality of noise reduction features (112). Each of the plurality of noise reduction features (112) inciudes a first surface (120) and a second surface (122). The first surface (120) inciudes a first portion (124) mounted to one of the pressure side (22) or the suction side (24) and a second portion (126) configured to interact with wind flowing past the other of the pres sure side (22) or the suction side (24). The second surface (122) interrupts an aerodynamic contour of the one of the pressure side (22) or the suction side (24).
