Effects of low-frequency noise from wind turbines on heart rate variability in healthy individuals
Abstract Wind turbines generate low-frequency noise (LFN, 20–200 Hz), which poses health risks to nearby residents. This study aimed to assess heart rate variability (HRV) responses to LFN exposure and to evaluate the LFN exposure (dB, L Aeq) inside households located near wind turbines. Thirty subj...
