I can't draw you the graph right now because i'm out but look up graphing calculator and click on the first one, type in your equation and it will show you the graph
Remember that sound intensity decreases in inverse proportion to the distance squared. So, to solve this we are going to use the inverse square formula:

where

is the intensity at distance 2

is the intensity at distance 1

is distance 2

is distance 1
We can infer for our problem that

,

, and

. Lets replace those values in our formula to find

:





dB
We can conclude that the intensity of the sound when is <span>3 m from the source is
30 dB.</span>
