Is there a way or formula, to find the distance sound can travel given a certain level of sound. For example, is there a way to find how far sound with the intensity level of 100 will travel? Please help! Thanks!

I am not asking anyone to do that problem. I am just using as an example to help you all understand what I mean.

When you say how far while the sound travel you really mean how far will it travel before it reaches some specified intensity level, 1/1000 of its initial intensity.

If it were a point source it would fall off as 1/r^2. If it's not a point source it depends on what kind of source it is.
