device to read volume level in a room Answered

I was just thinking that something like this might be handy for a teacher. If you had some device that could read the volume level in the classroom and display it in a bar format so the students know when they are getting too loud. It'd be nice to be able to say, "ok, you can talk with your group but stay under volume 5" or "if you keep it below volume 3, you'll get more marbles". Anyone know if this could be done and how?
