Question

What is the difference between loudness and intensity?

Answer 1

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

Answer 2

Answer:

Explanation:

Loudness is the measure of response of the ear to the sound. Intensity is the sound power per unit area.

Loudness is measured in decibels. Intensity is measured in Watt per meter square.

Loudness is dependent on the sensitivity of the human ears. Intensity is independent of the sensitivity of the human ears.

Loudness is a subjective quantity. Intensity is an objective quantity.
