I'm assuming you are riding with mirrors, but unless you
always remember to check them every N seconds, road noise behind you can be very useful (if nothing else, to remind you to check your mirrors now).
(If you aren't riding with mirrors, how do you know anybody is behind you at all if you aren't using sound?)
And for riding on MUPs, being able to hear the other bicyclists
("passing on your left") and pedestrians is quite useful. It's really annoying to have to communicate with a fellow bicycle rider on a MUP using an air-zound because they don't hear you.
