✦ Synopsis

The results of a theoretical investigation of point impedances at edges and in corners of thin isotropic and orthotropic plates are presented. These impedances for plates of reinforced concrete, steel and plywood were measured and compared with theoretical ones. The theoretical impedances at edges and in corners of plates are smaller than the measured ones, but they are in good agreement at the centres of the plates. This means probably that the classical theory of thin plate bending does not describe the motion at edges and in corners well. Vibration isolation was measured with the above-mentioned plates being installed on steel springs or rubber isolators. The measured vibration isolation agrees well with the predicted one if the impedances corrected according to the experiments are used.
