Abstract
The amplification of a shock wave pulse transmitted through a sand layer is investigated as a function of layer thickness. It is shown that, as the sand layer thickness becomes somewhat higher, the amplitude of the probing pulse first increases and then decreases. Pressure peaks form almost simultaneously throughout the entire sand layer.
