Ugh. Now you got me thinking about hearing my heart beats.
Next you'll start seeing your nose
(Sorry)
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
Yes all the time
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.

But that's the thing it happens at idle, and I've tried fixing it by unplugging+discharging and letting it sit unpowered in my colder-than-average room for 5 hours or so and it was still happening when I booted back up. So time or some other random thing seems to be a bigger difference.
When I had it not happen for days, doing anything that made the fans ramp up didn't cause it to happen (even full tilt as you said). In fact most of the time it'd start with nothing open other than the browser.
I thought it might've been dust (despite my PSU being the least dusty component) but after dusting it doesn't seem to have been the issue.
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.
I can’t of anything that makes an unwanted sound. Old CRT TVs used to, but I haven’t used one in years. My monitor at work makes a sound when it turns on or off (I believe there’s an ass-old fuse in there), but it makes no sound otherwise.
I’m still young and hear very well, as exemplified by my annoyance of half-closed bottles of carbonated drinks, which do make a sound.
I did a lot of stuff with CRT’s during ‘Rona and man sometimes that whine just pierced my ears - my dog (RIP love ya bud) would just look at me and slowly walk off every time lol
I can hear my phone charging.
I have like 2 USB chargers that are really loud.
Not after I stopped buying cheap power supplies.
- Belkin travel surge protector
- 5-port USB hub
- wireless charger
Thankfully none else!
I hear some of them. There's a real cheap one my parents got with a security camera thats real loud to me, but they don't hear it.
I did when I was younger but I don't hear it since I hit around 30
Yes, but a bit less as I've aged probably because the higher frequency hearing we have starts to diminish the older we get.
