What are the health effects of noise from wind turbines?

The article gives typical turbine sound levels of 35–45 dB at 300 metres and 60–80 dB at close range, and identifies gearbox/generator noise and aerodynamic blade noise as sources. It says amplitude modulation can create a noticeable “swishing” sound, especially in quiet rural settings, and that perception, visual presence, individual sensitivity and community involvement can affect annoyance.

On health, the page identifies sleep disturbance as the most commonly reported effect, while saying studies differ on the degree of impact and broad reviews have not found a consistent causal link to serious health outcomes. This is the article’s summary of cited literature, not clinical guidance. It claims low-frequency sound levels are generally below health-impact thresholds.

It gives examples of noise limits: Finland 45 dB by day and 40 dB at night outdoors near homes, the UK around 43 dB at night and Canada below 40 dB for dwellings. These are the article’s regulatory examples and should be checked against current local rules. Mitigation discussed includes turbine setbacks (commonly 300–1,000 metres), acoustic modelling, site monitoring, quieter blade and nacelle designs, building insulation, community liaison and early resident involvement.
