Answer:
More intensity of sound is corresponding to the more amplitude of sound which will increase the amplitude of sound.
Step-by-step explanation:
Amplitude of sound is proportional to the intensity of sound
As we know that intensity of sound is defined as the energy of sound passing through a given cross-section per unit time.
so it is defined as

we can also define it as power per unit area

so here we can solve it further and find that intensity is given as

so on increasing the intensity of sound we will have more amplitude so it will increase the loudness of sound.
