A spindle drive assembly for opening and/or closing a vehicle flap is described, having a spindle and a spindle drive motor coupled thereto by means of a two-stage epicyclic gearing. A ratio of a number of teeth of each planet gear of a first epicyclic gearing stage to a number of teeth of each planet gear of a second epicyclic gearing stage is selected such that, in operation, a first sound frequency that is emitted by the first epicyclic gearing stage differs by an integer multiple of a semitone from a second sound frequency that is emitted by the second epicyclic gearing stage. In addition, a vehicle flap with such a spindle drive assembly is presented.
