Popis: Adequate sleep is important for good health and well-being, and inadequate sleep leads to impaired attention and performance. Persistent poor sleep is also associated with cognitive and metabolic impairment, cardiovascular problems and diminished psychological well-being. Recent growth in wind farm developments has been associated with community complaints regarding sleep disturbance, annoyance and a range of health issues that some attribute to wind farms. Wind turbines create aerodynamic and mechanical noise that, if sufficiently loud, has the potential to disturb residents’ sleep, particularly for those living in close proximity. According to the World Health Organisation (WHO), noise effects on sleep are expected to occur with outside noise levels > 40 dB (A). On the other hand, the WHO guidelines also state that “when prominent low-frequency components are present, measures based on A-weighting are inappropriate”, so uncertainty remains regarding which alternative noise measures and noise limits are most appropriate to mitigate community impacts of wind farm noise on sleep. In Australia, dwellings are typically located > 1 km from the nearest wind turbine where wind farm noise becomes more biased towards lower frequencies ( $$\le $$ 200 Hz) at low sound pressure levels ( $$
