Do you often hear the ringing of switching power supplies and devices when you are in a quiet space? (lemmy.world)

I'm curious, how many people are aware of these sounds. I have designed, etched, and built my own switching power supplies along with winding my own transformers. I am aware of the source of the noise. So, does anyone else hear these high frequency sounds regularly?

We have a VR system set up in our living room. I don't even want to talk about how long it took me to figure out the receivers were making a steady, high pitched noise. There are 4 of them and they are situated near the ceiling.

I hear it from a lot of things when it's quiet enough. Clock radios, tvs, monitors, my pugmill, heaters. There was a noisy power strip with a flashing one-off switch that I'm still convinced was going to kill someone.

I DON'T know anything about electricity - so mostly it makes me anxious that my house is going to burn down. I have bad enough hearing loss that I have to use closed captions on my TV - but it IS mostly because deep voices are extremely muddled. I'm surprised a bit by how many "not really" answers I see.

I still don't get why the lighthouses can't be turned on/off via SteamVR. There's no reason they should stay running if I'm not actively in VR, and with the amount of noise they create, I have to imagine it's negatively impacting their lifespan.

One of these days, I'll get a smart plug for them, but I really shouldn't need to imo.

I leave mine unplugged. It would be nice if they would turn off.
