In the work under presentation it was performed theoretical analysis of acoustic field influence on processes proceeding into two-component medium which is fog (waterdrops suspended in the air). Acoustic waves may influence on media where they propagate.Acoustic field, except for the fact that causes to accelerate waterdrop coagulation process, influences kinetics of phase changes: water – steam (gas). If gas medium is not steam – saturated enough then under acoustic field, evaporation of waterdrops suspended in the air follows. If then gas medium is steam – saturated enough so under acoustic field increase in size of waterdrops follows (fog condensation). In the both cases the change of waterdrop radius value is observed, suspended in the gas medium and this causes the change of its clarity. Under specific conditions these processes cause fog dispersal, then it is possible to use acoustic field as agent causing increase in atmosphere clarity.
