The problem of determining the hydroacoustic properties of small material samples in small measuring chambers in the low frequency range is considered. The results of determining reflection coefficients using mathematical modeling are presented. The diagram of facility for measuring the hydroacoustic parameters of materials is proposed.

Key words: hydroacoustic properties, low frequencies, reflection coefficients, material parameters, mathematical modeling.
