Infrasound refers to sound waves that are too low for human hearing. Scientific research confirms that infrasound from wind turbines does not cause sleep or health problems.
In a recent Australian study by The Woolcock Institute of Medical Research participants were exposed to simulated wind‑turbine infrasound at levels comparable to real‑world conditions over 72 hours.
Researchers compared infrasound, sham infrasound, and traffic noise while monitoring sleep, physiology, and mood using detailed measurements, including overnight sleep studies.
The study found there was no effect from wind turbine infrasound on sleep quality, sleep stages, wakefulness, or wellbeing. Audible traffic noise, however, did disturb sleep by increasing night‑time wakefulness.
The researchers concluded that wind‑turbine infrasound, at levels measured in real environments, did not produce detectable negative effects on health or sleep.
