A noise reducer for a rotor blade of a wind turbine and a rotor blade assembly are disclosed. The rotor blade assembly includes a rotor blade having exterior surfaces defining a pressure side, a suction side, a leading edge and a trailing edge each extending between a tip and a root. The rotor blade further defines a span and a chord. The rotor blade assembly further includes a noise reducer configured on the rotor blade. The noise reducer includes a plurality of rods each having a body extending between a first end and a second end. The body of each of the plurality of rods contacts and extends parallel to the body of a neighboring rod of the plurality of rods when the noise reducer is in a stable position.
