These folks did a lot of measurement with low-frequency microphones and micro-barometers around large wind turbines and during a variety of weather conditions. A huge amount of work.
Some findings are: that wind turbine signatures are readily detectable up to 10 km under most weather conditions and that levels at the low frequency can be 10-11 dB stronger than the 6 dB per double-distance rule.
One interesting thing I found in here is that the sound power level emitted by a 3 MW wind turbine is up to 130 dB (relative to 10^-12 W) - as shown in Figure 13.
Bur - if we do the calculation per http://www.sengpielaudio.com/calculator-soundpower.htm and assume a directivity factor of 2 (reflection from the ground) then you find you need to be within about 125m to reach a sound pressure level of 80 dB.
So: if you are many km away from the turbine(s) it’s quite unlikely you will be exposed to a level that generates response in your OHC. Under unusual weather conditions, though, you might reach this level at a few km’s distance. This is a bigger distance than siting guidelines based on audible noise alone.
Using a 4-second measurement window you can detect wind turbine signatures well below the 80 dB SPL. And if your ambient is quiet enough, you can make an estimate of the actual sound pressure level by filtering down to a slice of 1 Hz BW. So if you think you have a problem from infrasound, you could establish that you are being exposed to it using RB (my conclusion).
