ELI5: Why do my ears ring in a quiet room?

Is it psychological, scientific reasoning, or does this also happen in louder surroundings and just goes unnoticed?

Edit: thanks for the responses and explanations!

It's called tinnitus. You probably have a very minor case of it.

It happens all the time but you don't hear it for the same reason that you can hear yourself type on a keyboard in a quiet room but not if you turn on loud music.
