ACOUSTIC FIELD EFFECT ON PARAMETERS OF MARINE ENVIRONMENT THERMODYNAMIC STATE

V. I. Babiy

Marine Hydrophysical Institute, Sevastopol

ABSTRACT
The additional fluctuations of thermodynamic sea water state parameters, conditioned by acoustic ocean fields are considered. The linear and quadratic approaches of the adiabatic equations of state, describing this effect are given. It is shown that linear approach is enough for sound small amplitude waves. Constant component, proportional intensity of the sound, appears in state parameter for waves of the big amplitude at quadratic approach. The quantitative estimations of the first and the second pressure derivations of adiabatic sound velocity equations and specific conductivity of sea water are presented. The insignificant role of nonlinear effects is noted for underwater acoustic ocean noise.

KEYWORDS
