Abstract: An illustrative embodiment of the present invention includes acoustic transmitting transducer apparatus for use in well borehole logging which provides a sharper, more intense pulse of acoustic energy than heretofore possible while at the same time eliminating undesirable electric fields in the vicinity of the transducer element. Novel circuit means including remote mounted charge storage means, switching means, voltage transforming means and isolation circuitry together with mechanical end clamping are combined to produce this result.
