Method for noise optimization of machine equipment comprising electric machine

The invention relates to a method for noise optimization of a machine installation comprising an electric machine (2), which is regulated by means of a regulating device (4) having a harmonic compensation regulating device (6), in which the following steps are carried out one or more times: a) selecting an operating point of the electric machine; the following steps b) to d) are carried out a plurality of times: b) a compensation parameter of the harmonic compensation control device is determined for the selected operating point, an initial compensation parameter is determined when the steps b) to d) are carried out for the first time, and a changed compensation parameter is determined on the basis of the determined quality values when the steps b) to d) are carried out continuously; c) operating the electric machine, the electric machine being adjusted using the compensation parameter; d) determining a quality value according to a predetermined noise evaluation scale on the basis of the machine noise during
