I don't need to turn anything off to hear mine 
It is there all the time quite loud. I suspect hearing damage at high school discos incurred as a teenager. I certainly had ringing in the ears after a few of those.
Mine sounds like high pitched cicadas (probably a mish mash from 14khz up to maybe 16 or 18khz). I actually can't hear any real sounds past about 13Khz (that's how I know what the frequency of the ringing is, as it is higher than I can hear) It does vary in loudness, but never goes away.

Try and borrow a sound level or noise meter to see what the background level is when everything is on and powered up.
I usually get 40-50dB at home. Surprising really. Oh for some quiet, but then I would hear my thoughts...
For sure. I have to turn these things off as well when listening to noise output of my amp projects, part of my procedure for nabbing down pesky sources of HF oscillation. I use to live in a place where a freight train passed every 40min but now I get to listen to quite a bit of air travel, smaller aircraft, so a moment of complete silence is rare.
Ears can play hallucination tricks on you with complete silence like your eyes do when in complete darkness. Try to listen to your heartbeat so your aural senses have something to focus on.
yes, stress plays a really big role
noisy elctronics and poorly designed speaker, equally bad
and it might be wise to avoid non-shielded signal connect wire, but use only shielded types
and make sure all your PC electronics is properly grounded(earth)
and especially your PC stuff should have mains filters
well, I burned my mains filters, so it might not be simple
point is that some of the noise you hear actually is real, even if you cant locate it
the bad side could be that your own ear actually produce part of it, by itself, as a result
What? What did you say? Yeah, me too... ;(
Very handy, a sort of reverse alarm clock.
It's amazing how quiet it gets when the power goes out. Until my generator kicks in. When I loved at the beach it was never quiet, trade winds blowing all the time, traffic, people. But up the mountain at 7000 ft it was beautiful. Almost no sound at all. Could hear flies buzzing at 20 yards or more. Just wonderful.
It is cold here nowadays, +17to +28deg C(don't laugh, 17 is too cold for us) We do not use fan and there is no ringing in the ears when power fails.
After returning to land from a ship cruise for a long period, u start to feel the roll and pitch for nearly two days, an after-effect. This ear thing looks to be
similar.
