Research

Assessment of low-frequency noise from wind turbines  This work tries to estimate the sound power level of wind turbines (LW,A (dB)) at 20–200 Hz, which are not provided by manufacturers but essential for estimating LFN exposure (LAeq) of nearby residents. This study successfully determined and validated the LW,A of wind turbines of three brands, and subsequent residents’ LFN exposure (with 1.5 dB difference) at three wind farms. Accurately obtaining LFN exposure will serve as the basis for assessing LFN exposure-health relationship. As wind power widely use worldwide, health impact should be assessed based on validated LFN exposure assessment [1].

Effects of low-frequency noise from wind turbines on heart rate variability  The study assessed heart rate variability (HRV) response to LFN exposures and that evaluated the LFN exposure (dB, LAeq) for residents in households indoor. Our results showed that in every 1 dB (LAeq), subjects’ SDNN (standard deviation of all normal to normal R-R intervals) reduced by 0.43 %, in the range of 38.2-57.1 dB (LAeq). Results of household monitoring showed that indoor LFN exposures (LAeq) were 30.7-43.4 dB (LAeq) at a distance of 124-330 m from wind turbines. Moreover, households with concrete and airtight windows are the highest LFN differences between indoor and outdoor, compared with households with concrete and/or brick. In view of the adverse health impact of LFN exposure, there should be regulations on requisite distances of wind turbines from residential communities for health protection. (Paper to be submitted)
