ACOUSTIC FIELD INFLUENCE ON THERMODYNAMIC STATE PARAMETERS OF THE SEA WATER
Additional fluctuations of parameters of thermodynamic sea water state are considered, conditioned by acoustic fields of the ocean. Linear and quadratic approaches of the adiabatic equations of state, describing this effect are given. Linear approach is shown to be enough for sound waves of the small amplitude. Constant component, proportional intensity of the sound, appears in state parameter for waves of the big amplitude at quadratic approach. Quantitative estimations of the first and the second pressure derivations of adiabatic sound velocity equations and specific conductivity of sea water are brought. The insignificant role of nonlinear effects is noted for underwater acoustic ocean noise.
