An experiment on measuring the pressure wave amplitude distribution along the height of a ``cold'' model of the liquid core of a continuous ingot excited by the pinch effect in the upper part of the liquid core is described. An approximately 6.8-fold increase in pressure amplitude was recorded near the model bottom. It is shown that this effect is determined, in the main, by the conical configuration of the liquid core. Figs 5, Refs 3.
