Sammanfattning/Abstract: Two aspects of ambient noise masking of sound from wind turbines are highlighted: the development of a prediction model for vegetation noise and the relative levels of ambient noise needed to mask wind turbine sound. The prediction model for vegetation noise has been compared with an earlier method with notable improvement, turbulent wind speeds are combined with the prediction model and a new model describing noise from deleafed trees are presented. A loudness test suggests that annoyance will occur at levels where the wind turbine noise exceed natural ambient noise by 3 dBA or more.
