- knicholes 7y agoOh wow! This wasn't the one I was talking about, but very cool nonetheless. It's similar, but with keyboards. I hate posting this without evidence, but I think there was also something having to do with watching a plant or a pane of glass vibrate to know what is being said inside a room. The keyboard noise and the vibrations may also be unrelated. If I can find these articles, I'll come back and post them here.
- jmkni 7y agoI have a bad habit of mumbling to myself what I am typing, when there is nobody around, sometimes I will even read aloud what I just typed back to make sure it makes sense. If I was to use a Typewriter, you could probably put a recording device inside it and work out what I was writing about that way.
