| Research Abstract |
In this study, the field measurements of noise from a single wind turbine were made in several terms, in order to examine the radiation characteristics of noise generated from the wind turbine. As a result of this study, it has been found that the A-weighted sound pressure levels in the upwind and downwind directions of the wind turbine are almost the same and are 5 dB larger than those in the crosswind direction. There are not any significant differences in the vertical distribution of noise emitted from the wind turbine. The noise level distributions at distances up to 200 m are similar to the calculated values assuming the wind turbine to be a circular plane source.
