Delivering a thumping, grinding, mechanical cacophony, industrial wind turbines drive neighbours nuts. But, as a recent study from Flinders University in South Australia has found, there’s a reason why wind turbine noise is so much worse after dark.
The pulsing, thumping nature of wind turbine noise – which relates to blades passing the tower – is referred to as ‘amplitude modulation’ (AM). And it’s the peaks and troughs in sound pressure levels that makes living with wind turbine noise a daily misery for thousands around the world.
But changes in humidity, temperature, atmospheric pressure, wind speed and direction all have a part to play in how the wind industry’s victims get to experience AM in the range of other unnatural noises generated by these things.
Over the last four years, Dr Kristy Hansen and her PhD candidate Duc Phuc Nguyen have been researching the complex nature of the noise from…
