A reciprocity system has been developed for the absolute acoustic calibration of small hydrophones at hydrostatic pressures up to 15 000 psi and frequencies to 400 cps. The method involves electrical measurements on three transducers placed in a closed, stiff‐walled “coupler” vessel and a measurement of the static acoustic compliance of the coupler.
