Literature sources [10], [21], 22, [23], 24 and 25 demonstrate that WT acoustic noise level is rather high. All this should be considered when constructing WT, since noise level should comply with normative requirements, i.e., to not exceed a 45 dB(A) level in the residential areas 26 and 27. The level of WT noise at rotor axis height depends on WT type, tower height and wind velocity. Enercon type WT noise level varies within the limits from 89 dB(A) to 104 dB(A) (Table 1). It may be observed that with the increase of WT capacity or wind velocity, the intensity of the spread noise increases as well.
