Question

distinguish between loudness and intensity of sound any two

Answer 1

Loudness is related to the amplitudeof sound waves (or pressureamplitude/ displacement relative to atmospheric pressure, typically), whereas intensity is the rate at which power (rate of energy transfer, or work per unit time) is transferred across a given area (Power/Area, or rate of energy transfer per unit area

Answer 2

Sound intensity is a property of the sound source but loudness depends on the sound source, the medium and the receiver, as well.
Sound intensity holds a small significance in problems involving human hearing system, but loudness is a very important property to consider in such problems.
