This means there are roughly 44.7 million unique sources of infrasound in Australia. Infrasound Measurements – Rural environments Wind farms are almost always placed in rural environments.

The infrasound levels recorded near 25 100-metre high wind turbines ranged from 66.9 to 88.8 LGeq across different recordings. Those recording infrasound in noise from wind in a forest near houses ...

Infrasound is sound below 20Hz, which is generally inaudible. Wind turbines are just one source of artificial man-made infrasound.
