This thesis deals with basic investigations into damping effects in the field ofbuilding acoustics. Special interest is paid to the damping of a partition wall in a laboratory test facility. This damping directly affects sound insulation whichis the most important quantity in building acoustics. In accordance with the results of earlier examinations, the investigations were applied to small downscaled models. These offer the advantage of the exact execution of construction and of freely selectable material propertiesand allow idealised constructions to be realised. Firstly, the necessary theoretical and experimental bases were provided for the design of the downscaled models. Extensive investigations into material properties led to the parameters required for the experiments and simulations. Thereafter, the individual effects that lead to the damping of the partition wall were determined as loss factors by experiment. A simulation undertaken by means of statistical energy analysis (SEA) allowed detailed insight into the energies and power flows of the system in total to be gained. Both the experiment and the simulation showed in agreement that the power flowing from the facility into the partition cannot be neglected a priori as has been common up to now. Depending on the laboratory situation, effects which have been thought of as loss effects to date can be turned into gain effects for the partition. Moreover, the standard procedure for measuring the total loss factor, which is the main measurement for damping, was analysed by a transient SEA simulation. In agreement with model measurements, it could be shown that, due to the complex power flow in a wall test facility, the total loss factor is determined as much too low for typical standard situations. The insights gained about the damping of a partition wall in a building acoustics test facility explain previous discrepancies but also raise some new questions of a basic nature. In future, more effort will be required in practise to determine the influence of damping. This thesis offers a starting point for that.
