Ok I can say for absolute certainty it is not a car or truck idling. This is a very strong sound and it's coming on and off all day and all night.
The volume of it never changes, either. I did think about the underground tunnel stuff, or seismic activity of some kind. I have gone exploring outside trying to find a source but it's just "everywhere". I understand the non-directionality of low frequency but it has that "airy" frequency in it too, like white noise that should be more definable.
I don't really expect anyone to have a definitive answer but I wanted to test the waters to see if this is a more widespread phenomena. I'd like to try to get a recording somehow but I don't know how I'd go about it.

My 4 year old son is hearing this hum too & we are in Australia. He says its loud & he mainly hears it from lunchtime onwards. My husband, daughter & I can't hear it or his teachers at pre-school. We don't know how to proceed, any info or research will be greatly appreciated.
