ABSTRACT:
An acoustic pressure pulse generator has a pressure pulse source in the form of a concussively driveable membrane, the membrane limiting a volume within the generator which contains a liquid acoustic propagation medium, the generator also having a wall therein spaced from the membrane, the wall dividing the volume into two sub-volumes. The acoustic propagation medium is circulated through an inlet in one of the sub-volumes and an outlet in the other sub-volume, with the two sub-volumes being in fluid communication via a flow restrictor through which the acoustic propagation medium flows. The restrictive effect of the flow restrictor is dimensioned so that the acoustic propagation medium contained in the sub-volume between the wall and the membrane is maintained at a pressure for effecting return of the membrane to its initial position after the membrane has been concussively driven.
