I'm really confused on this one too..(adsbygoogle = window.adsbygoogle || []).push({});

The intensity of the sound from a certain source is measured at two points along a line from the source. The points are separated by 13.1 m, the sound level is 71.30 dB at the first point and 63.20 dB at the second point. How far is the source from the first point? What is the power output of the source?

I've looked all through my notes and the book and i can't find an equation to help
