Thanks Natsman, I'm pretty sure it's not tinnitus, because I've had the
condition for the past 30 odd years. Tinnitus I have can be heard wherever I
am. The low frequency hum, seems to be resonating the brickwork of my
house, as it's inaudible if I go outside and move away from the house.

For the first few nights I couldn't sleep properly, but since then, I've just took
no note of it.

This is a worldwide but fairly localised phenomenon that's been
documented for many years but, to the best of my knowledge, never fully
explained.

Many people have experienced it in my home town of Largs, Ayrshire. It
really is an environmental health issue there as it seriously affects
the well-being of the more susceptible people. Do a Google search on
"Largs hum" and you'll find a lot of stuff.

This site documents a number of UK occurrences:
