It is an absolute method for the calibration of the free-field sensitivity of hydrophones. Usually, the calibration is carried out in an open water tank. In this paper, the calibration of a B&K8105 hydrophone in a closed acoustic vessel was described. The comparison results between the optical method and the reciprocal method were in good agreement with each other. It showed that the optical method had potential applications for the calibration of hydrophones in a pressure vessel in future.", }
