A method for noise reduction of a three-phase-driven electrical machine includes recording an angular state of a rotor of the electrical machine, calculating a reference frequency on the basis of the recorded angular state, forming a sine and cosine value of the calculated reference frequency, and filtering the sine and cosine value. The method may also include recording a sound-related feedback variable, forming a weighting vector, forming a superposition signal, and applying the superposition signal to a manipulated variable of the electrical machine.
