A satisfying solution, considering the different construction principles of lightweight floors, could not be found so far. To overcome this problem a FEM based prediction model for the optimization of the floor construction and the improvement of the impact sound insulation has been developed and applied in a current research project at th e TU M{\"u}nchen. The details of the prediction model were published in [1]-[3]. This contribution gives an overview of the prediction model and shows the results of the computations and the construction rules developed for optimized lightweight floors.}, language = {en} }
