Three-dimensional model experiments broaden in principle the class of solvable problems, if compared with two-dimensional model experiments. In particular, the determination of the energy balance during the wave generation by a small explosion inside the medium becomes possible. The corresponding experiments require a well-calibrated instrumentation.
The procedure of the experiment and the calibration of an apparatus involving displacement-type transducers is described. The calibration is based on a generalization of the shake table concept to the frequency range of interest in model experiments.
