hmm

I'm pretty sure I can hear when I turn a page on my e-reader. Like when the display refreshes or something

however, it is extremely quiet, quieter than most electrical hums around me

... why is my hearing like this

[miawinter@tech.lgbt]

honestly one day I would want to sit in one of these -20dB chambers

just so I know what silence is like

[miawinter@tech.lgbt]

oh wait when I put my ear right up against it it's relatively audible

huh

how the fuck did I hear that from a distance

[miawinter@tech.lgbt]

It is incredible quiet, but audible

I wonder what is making that noise

[v@mastodon.catgirl.cloud]

@MiaWinter the coils must whine! of something

[miawinter@tech.lgbt]

yeah damn you need headphone to have even a chance to hear it

my speakers can't do it

[desea@snug.moe]

@MiaWinter have you looked at how e-reader displays work? its very interesting, solid particles suspended in a liquid so makes sense theyre audible

[miawinter@tech.lgbt]

@desea yeah but this is... not what I expected to hear

it sounds like a scanner head, but tiny and fast

[mayabotics@tech.lgbt]

@MiaWinter I can't hear the noise since my high frequency hearing has declined over the years, but if I had to guess, I would suspect coil whine from the boost converter.

I believe e-paper displays use a "high" voltage pulse to do a full refresh.

@MiaWinter i now need to listen to my e-reader in a completely quiet environment and see if it does it too
