Noise Directivity
The physical property whereby noise radiated by a wind turbine varies markedly with propagation direction; influenced by blade rotation, nacelle geometry and tower shielding, sound pressure levels downwind and to the side can differ by several decibels.
Timeline (last 90 days)
The noise radiated by turbines varies significantly with propagation direction, with sound pressure levels differing by several decibels between downwind and lateral directions.
Yaw angle not only changes the propagation path of wakes in the wind farm but can also affect the directionality of noise emission.
