Early PCs didn’t play beep-boop sounds when you typed or when displaying a letter on the screen either, so join the crowd. I mean, people would have shoved a screwdriver through the speaker diaphragm if they had to listen to that all day.

If you go all the way back to teletypes, okay, there was an impact sound, and computer keyboards were significantly noisier up until membrane and rubber domes became popular, but that’s about as far as reality takes one.
