Another piece on Infrasound (thanks to G3RM). This inspired a quick search, which revealed:
A paper on infrasound by John D. Cody.
The Sonic Weapon of Vladimir Gavreau
NOAA Environmental Technology Laboratory Infrasonics Program
Intro to Infrasound Java demo
Calculation of Infrasound frequency weighting (apparently called the G-weighting, what happened to E and F?)
And interesting uses for infrasound include monitoring for banned nuclear tests and forecasting surf.
British government acknowledge that not all 'hummers' are suffering from low frequency tinnitus.
Defra report

I’m always wary of people who claim to suffer from low frequency noise, as I know of cases where people have insisted it is coming from one particular source (even though they have no way of knowing where its coming from) just because they want to see that particular company moved further from their home for other unrelated reasons. However, it is very difficult to prove either way, as there may not be any measurable sound causing it. One case I know of the sound the person was hearing turned out to be sound of their own cochlea expending and contracting as a nearby radar station warmed it up when switched on and then allowed it to cool when switched off. Obviously that cannot be measured with traditional acoustic equipment.

Should anyone stumble across this looking for help with low frequency noise, the Low Frequency Noise Sufferers Helpline is contactable here.
