    Abstract: An experiment that was performed to confirm the possibility of free-field calibration of receiver of sound field vector quantity in a reverberant sound field of a water tank during radiation in a water tank continuous signal with a frequency-distributed power is described. The purpose of the experiment was to introduce reference distortions with known parameters into the projector direct wave and make sure that the distortion parameters measured by vector receiver in the reverberant field coincide with the predicted ones. The reference distortion was introduced by a sound wave reflected from the water-air interface. The proposed technique let experimentally establish the possibility to select in the reverberant sound field of water tank the vector quantity of projector direct wave in the frequency range overlapping the range of the tone-burst method and continued up to frequencies of standing sound wave chamber.
