It's the rat's fridge then@Madrab It's a constant hum kind of ring like the noise the fridge makes but quieter as though under the floorboards but still there with power off to house.

Others would not have the same tinnitusTinnitus
I think I had that with an led dedicated dimmer switch if I listened closely I could hear a humThanks it's definitely not Tinnitus as others can hear it. I just had a new light fitted and the electrician could also hear it.
The rat has enslaved an hamster to run in a wheel powering his fridge...@johnny2007 Ah but it's still there with power off so how's he running it?
Do you have a battery operated doorbell?
Mine has a very faint buzz that drove me mad until I discovered it.
I was the only one who could hear it and my wife thought I was mad.
Turned out my hearing is better than it should be at my age.
Anyhow, look for any battery operated device and let us know.
