Sleep deprivation, including arousal from deep to more shallow sleep, can cause many adverse health effects, including many of the symptoms reported by neighbors of large wind turbines. The World Health Organization notes that an average inside noise limit at night of 30 dBA or lower (for pulsing noise and low-frequency noise, both of which characterize the noise from wind turbines) is needed to protect sleep and thereby health.
