Assessment of low-frequency noise from wind turbines under different weather conditions.

ABSTRACT:

Background

Low-frequency (20-200 Hz) noise (LFN) from wind turbines has received much public attention due to potential health concerns. This work tries to estimate the sound power level of wind turbines (L _W,A (dB)) at 20-200 Hz, which are not provided by manufacturers but essential for estimating LFN exposure (L _Aeq) of nearby residents.

Methods

L _W,A at 20-200 Hz at three wind farms, each with a different brand of wind turbine (Brands A, B and C, respectively) were estimated using propagation model ISO 9613-2 under different weather conditions (rain, wind speed and wind direction) and validated with LFN monitoring data. The feasibility of using validated L _W,A as inputs for ISO 96
