Detailed Solution

The above statement is True.
The loudness of the sound refers to how large the amplitude of the sound wave is. The decibel (dB) scale for measuring loudness varies directly with the square of the amplitude of the vibration.
Loudness

\propto

(Amplitude)2
Factors affecting the loudness of sound are the surface area of the sounding body (i.e., the loudness of sound is directly proportional to the surface area of the vibrating body), the distance of the source of sound (i.e., decreases with distance), the amplitude of the wave (i.e., increases with amplitude).
