Question

Distingush between loudness and intensety​

Answer 1

Loudness is related to the amplitude of sound waves (or pressure amplitude/ 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

Hi my dear friend,

Loudness is actually the perception of sound by the listener. 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 is measured in Watt per square meter whereas loudness is measured in Sones.
