ABSTRACT:
A method for testing hydrophones in situ by means of a pulser for applying a repeatable low-level pressure pulse to individual hydrophones mounted in a marine seismic streamer cable. The transient output signal, due to the applied pressure pulse, from any one hydrophone under test is compared with the transient signals from other hydrophones under test to determine uniformity of response with respect to signal polarity, amplitude and period (reciprocal frequency).
