Abstract: Wind energy is developed strongly for meeting different energetic needs in populated territories. In such environmental impact assessment of field devices there are emphasized acoustic pollution problem, which is estimated within the pale of acoustic pollution. They can be measured if origins of noise parameters are known and its location conditions. Using the mathematical research methods of noise created by analogical energetic resources the assessment has been done and the mathematical model of a dotted voice source was adapted in the more difficult geometrical forms and dimension for resource acoustic emission summary. In accordance to geometrical acoustic rule the intensity of acoustic emission, which is evaluated as is estimated as the recede of the noise resource in r distance, was estimated and is expressed as formula 10lg(1+(h/r)2)/r2, dBA. Also the acoustic noise level of wind farms assessment was done and acoustic noise dependence in different distances from wind farms gas been made
