N2 - Aeroacoustic noise from a wind turbine is mainly caused by the interaction between the wind turbine blade and the air flow. For a modern wind turbine, trailing edge noise is often the dominant noise source. In this paper, a detailed study of trailing edge noise is carried out using Amiet's frequency domain analytical source model. Model results are compared with experimental data. Features of wind turbine noise, such as amplitude modulation, ground directivity, influence of blade twist and pitch are studied. In the last part, the influence of realistic wind profiles is investigated. Wind shear is seen to increase the sound power level and the amplitude modulation.
