    Abstract: The data on the standard facility for calibration of underwater sound receivers in the reverberant laboratory water tank are presented. The standard facility implements the measuring procedure of the reciprocity method in the free field of a spherical traveling sound wave using three transducers. A feature of the standard facility is the measuring by the absolute method the free-field sensitivity of hydrophones and receivers of vector quantity of underwater sound field. During measurements, the free-field conditions are provided by using the method of time gating of tone-bursts and the technique of complex moving weighted averaging. The results and uncertainty estimation of calibrations performed using the standard facility are shown.
