I've got a bell AND an AirZound on my commuter bike - bell for peds, horn for cars and emergencies.
If I'm on my road bike, and I'm coming up on someone, I've changed to saying "Coming up...on your LEFT.". Adding the extra phrase on the front of it seems to reduce the panicked jumps to the left. I'm a bit more vocal if they're hogging the center, or a group is walking 3+wide and into the other lane.
....if they're doing the above, AND on a cell phone, I give them the AirZound.
