Answer 1

Answer:

The loudness of sound is a phenomenon of a sound depending on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud. The loudness of sound is directly proportional to the square of the amplitude of vibration and it is expressed in decibel (dB).

Answer 2

$\huge\sf\green{ANSWER}$

Loudness is the response of ear to the sound. Loudness is proportional to the square of the amplitude of the vibration body producing sound.

Loudness of a sound depends on the amplitude of the vibration producing that sound. Greater is the amplitude of vibration, louder is the sound produced by it.
