The sound designer needs to come up with it, given how loud the sound file is 
at full volume compared to how loud it should be at a given distance. Each 
sound will need manual adjustments made by ear. If you have any information 
about how the sound was recorded (e.g. if it was quiet near sound or a loud 
far sound) and what processing was done to it (e.g. if it was boosted or 
attenuated, and by how much), that can help guide you to proper values, but 
ultimately it needs some trial and error.
