G.I.Sokol A technique for calculation of acoustic fields of wind power units: An infrasound in wind power engineering |
Acoustic bulletin, Vol. 14 ¹ 3, (2011) |
| The paper deals with considering of physical reasons for occurrence of acoustic fields generated by operating wind power devises. The analytical expressions are obtained that allow analyzing of the characteristics of mentioned fields. The calculation techniques for determining the frequencies, sound pressures and directional characteristics are developed. |
