ABSTRACT:
Apparatus for generating an acoustic pulse in a medium including an upstanding cylindrical housing within which an impact piston supported by retainer springs is adapted to be propelled downwardly by high pressure expanding gas supplied from external high volume accumulators so as to a strike target plate resting on the ground adjacent the lower end of the housing. A small valve in the top of the cylinder is opened to supply sufficient gas pressure to overcome the spring bias and initiate piston motion. When the piston moves downward far enough to expose multiple large area ports in the housing side wall interconnected with the accumulators, the sudden inflow of gas pressure produces rapid piston acceleration and high energy impact with the target.
