I can't hear it but I can often tell when it clicks over because it causes a spike in my tinnitus.

I have tennis and can still hear the noise. Itβs weird. I have that background noise but I can still separate it from the other sounds around me. I actually went to do an audio test recently and had perfect hearing except I that I also hear extra things. Annoying as hell.
My monitor has a power led that blinks when in stand by (and not receiving a signal.
And the coil whine between the onn/off-switching is audible.
It is never quiet enough in my house to hear myself think without difficulty, so it definitely never gets quiet enough for that.
I really only notice them when the rest of the room is silent. Otherwise my brain ignores the sound most of the time.
When my monitor is on stand-by the led slowly blinks and every time it turns on I can hear it. Aside from that, I don't think so.
Ugh. Now you got me thinking about hearing my heart beats.
Next you'll start seeing your nose
(Sorry)
Yes
Everyone with fully functioning ears can hear it if they pay attention. Just a reminder to protect your hearing!
Inside your ear are hair cells that detect sound. You're born with the only hair cells you'll ever have, and damage to them is irreparable. Hair cells naturally sustain damage over time and people's hearing decreases as they age. This process is accelerated if someone constantly listens to things at loud volumes. So, maybe don't turn it up to 11!
Yes all the time
I canβt of anything that makes an unwanted sound. Old CRT TVs used to, but I havenβt used one in years. My monitor at work makes a sound when it turns on or off (I believe thereβs an ass-old fuse in there), but it makes no sound otherwise.
Iβm still young and hear very well, as exemplified by my annoyance of half-closed bottles of carbonated drinks, which do make a sound.

My friends and I used to drive out to an area of the desert, away from people and the general noise of civilization. However, there were large power transmission lines going through the area and we could listen to them crackle in the night as we watched the stars. Just a nice way to relax and get away from it all.
Even past 30 and with (mild) tinnitus, yeah my hearing is still great so I'm going to hear it. Light bulbs, chargers, the router etc.
Recently my computer's PSU has started randomly buzzing a not-quite-high frequency. It could be age (it's from 2019) though I'm pretty sure it's some kind of interference because sometimes it won't make any noise at all for days and I'm pretty sure my light bulb (an LED filament bulb which doesn't have much in the way of components) seems to also make different pitches of buzzing that coordinates with how much my computer PSU will buzz.
Anyways it bothers me, so as soon as I post this I'm going to power-down and unplug my computer and switch to a different device for the next day or so.
The switching frequency is usually set by a small capacitor that is on the mains auxiliary power circuit. This may degrade depending on what kind of capacitor was used. There is also a small electrolytic capacitor that smooths the auxiliary power for the chip itself. If this capacitor degrades too much, it can cause some switching frequency stability issues too.
My current laptop supply sounds about like R2D2 when my GPU is running full tilt and I'm maxed out on 18 of 20 cores with AI.

I can hear my phone charging.
Not after I stopped buying cheap power supplies.
I have like 2 USB chargers that are really loud.
