A method for the noise modulation of a three-phase synchronous electric motor driven using a vector regulation by means of a motor control unit. Actual values for the rotated current components id and iq may be obtained in an open-loop control system, where id corresponds to the magnetization current and iq corresponds to the torque-forming current of the synchronous motor. The actual values may be compared with predetermined reference target values, and the differences between the actual values and the reference target values may be converted into control variables to regulate the actual values (iq, id) to the reference target values. The magnetization current-forming current component (id) may be adapted using an acoustic controller to a desired acoustic state depending on an acoustic state that was measured by a measuring device and was transmitted to the motor control unit.
