______________________________________________________________
The intensity of a sound wave is said to be the sound energy passed through a unit per area .
while the loudness of a sound is depend upon its amplitude .
______________________________________________________________
Difference:-
Intensity :- 
1)It is the  sound energy passed through a given point
2)It does not depend upon sensitivity of ear
3) its unit is watt/m²

Loudness:-
1) it is the measure of response of our ear to the sound
2) It is relative because it depends upon both intensity and sensitivity of ear.
3) its unit is decibel
