There is an approach, named the vector-phase methods, based on enhanced amount of the acous-tic field information extracted from each point of the field at the present samples volume. They are realized by setting both receivers of sound pressure and gradient pressure or oscillatory ve-locity ones simultaneously in the limited number of medium points. Usually there we obtain the oscillatory velocity projections on vertical Vz and two horizontal (Vx, Vy) directions in the space. In spite of the fact, that vector receivers are used in hydroacoustics more than 30 years, until now exists much undecided problems, concerned with possibilities their practical using. The experimental and theoretical researches made for a long time at acoustics department of Physics Faculty of Moscow M.V.Lomonosov State University have allowed formulating a num-ber of approaches to the decision of some important problems of acoustics. The application of these methods for the solving of practical acoustics tasks is being discussed in this paper. We will select two reference direction of the vector receivers’ using: for study of the acoustic noise fields’ structure in the ocean and for decision of the hydroacoustics practical applied problems.
