Question

Differentiate between loudness and intensity

Answer 1

loudness is the characteristic by virtue of which a sound with high amplitude can be distinguished from a sound of low amplitude both having same pitch and quality

while ...

intensity of a sound wave is the amount of sound wave passing per second normally through a unit area .



loudness is subjective and cannot be measured
while
intensity is objective and can be measured

Answer 2

TUTOR

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; units of watts/m2).
