Answer:

The right approach will be "1.3". A further explanation is given below.

Explanation:

As we know,

In Decibels, the change in sound volume will be:

= [tex]10log\frac{I_1}{I_2}[/tex]

Now,

According to the question,

⇒ [tex]1=10 log \frac{I_1}{I_2}[/tex]

By applying cross multiplication and putting the value of log, we get

⇒ [tex]10^{\frac{1}{10} }=\frac{I_1}{I_2}[/tex]

⇒ [tex]1.26=\frac{I_1}{I_2}[/tex]

⇒ [tex]\frac{I_1}{I_2}=1.3[/tex]
