Abstract
An array of acousto-electric transducers 1,2, e.g. a hydrophone streamer, is calibrated by disconnecting the common ground wire 17, to which all the transducer shields 14 are connected, from ground and connecting it instead to a local oscillator 18. Test signals from the oscillator are capacitively coupled into each transducer via the inherent capacitances of the insulated lead throughs 15, 16 in the transducer shields 14.
