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, or amount of energy, in sound waves. The unit of intensity is the decibel (dB). As decibel levels get higher, sound waves have greater intensity and sounds are louder.

Answer:
Hello,
The loudness of a sound is determined by its amplitude. As the amplitude increases, the loudness of the sound also increases. If the amplitude is very small,the sound is faint and cannot be heard.
