Myself and my mate tested this. I would turn around and face the other way and he would start running and stop when I heard him.
It looks like 15M is it.

Bit of a bugger when someone is running around outside a building your in, or coming up fast behind you, You won't hear it until they are right up on you.
Sound needs to take in consideration: Type of footwear, Terrain, Speed of travel.
Bit frustrating too when you can hear someone reload or open a can of drink from about 40m away in another building.
