FIELD: hydro acoustics.
SUBSTANCE: invention relates to hydroacoustics, specifically to combined acoustic receivers. Spherical hollow body of receiver includes at least two holes located on one line on diametrically opposite sides of housing and closed by elastic impermeable membranes. Housing is filled with fluid with density lower than that of water. Rigidly fixed inertial mass with six sensitive piezoceramic elements of vector channels placed along the axes of the orthogonal coordinate system is installed in the center of the housing. Inertial mass is equipped with through holes and a central cavity, inside of which a hydrophone with electrodes for signals removal is rigidly connected in the geometrical center of the receiver, and the sensitive elements and the hydrophone are equipped with preliminary amplifiers.
EFFECT: invention can be used to carry out vector-scalar measurements of parameters of ocean hydroacoustic fields.
