This should still work on quiet keyboards--it just requires a bit more work in setting up a listening device. For example, you could hide a microphone under the keyboard or attach it to the table it's sitting on (and maybe adjust the model accordingly). I need to break out my relay board to see if the sound of the relays clicking mitigates attacks like this: https://youtu.be/6hMOGKTudcg https://youtu.be/6hMOGKTudcg (see it in all its clicky glory!) As long as the click of the relay happens fast enough--and I add some sound dampening to the keyboard (which was the opposite of what I did for that test video haha)--I bet it would render this kind of attack useless.
