Why is the American system a mess? One chime for up, two for down. It's simple and doesn't bother anybody.

  (speaking as a person who isn't blind) The biggest omission seems to be that there is nothing to tell you what floor you've arrived at. This is probably fine for an empty elevator but as soon as it gets busy and there are 10s of floors I'd imagine it gets hard to navigate.
