Question

differentiate between loudness of sound and intensity of sound​

Answer 1

$\underline \mathtt{loudness \: of \: sound}$

• The sensation produced in the ears which enables us to distinguish between a faint sound (feeble sound) and a loud sound is called loudness of sound.
• Loudness of sound is measured in the unit of decibel (dB)
• Loudness of sound depends on the sensitivity of ears.

$\underline \mathtt{intensity \: of \: sound}$

• The average of energy transported by a sound wave per second per unit area (perpendicular to the direction of propagation) is called intensity of sound.
• Intensity of sound is measured in the unit of Watts per square metre (W/m sq)
• Intensity of sound does not depend on the sensitivity of ears.

Answer 2

Answer:

Loudness refers to how loud or soft a sound seems to a listener. The loudness of sound is determined, in turn, by the intensity of the sound waves. Intensity is a measure of the amount of energy in sound waves. The unit of intensity is the decibel (dB).
