Answer:

The intensity increases by a factor 100.

Explanation:

Given that,

Sound intensity = 20 db

We need to calculate the intensity factor

[tex]F=10^{\dfrac{LI}{10}}[/tex]

Where, LI = sound intensity

Put the value into the formula

[tex]F=10^{\dfrac{20}{10}}[/tex]

[tex]F=10^2[/tex]

[tex]F=100[/tex]

Hence, The intensity increases by a factor 100.
