Expert Answer:

Loudness is a measure of response of our ear to sound. The unit of loudness is decibel.  It depends on amplitude. If the amplitude is high, the loudness also will be high.

Sound intensity is the sound power per unit area. The sound intensity is directly proportional to the square of the amplitude of sound wave.
