As the problem states, to solve this, we are going to use the equation 
where
is the loudness in dB
is the intensity of a sound
<span>is the minimum intensity detectable by the human ear
</span>
We know for our problem that
; we also now that the minimum intensity detectable by the human ear is 
, so 
. Lets replace those values in our equation to find :
Qe can conclude that since the explosion is under 100dB, it does not violates the regulation of the town. We used tow physical values to calculate the answer: the intensity of the sound of the explosion,
, and the minimum intensity detectable by the human ear 
.
