Question

definition of loudness for class 8​

Answer 1

Loudness: Based on the amplitude of a sound wave, we can determine the loudness of the sound. When the amplitude is high, it will produce a sound that is loud and when the amplitude is low, it will produce a sound that is soft. Loudness is proportional to the square of the amplitude.
