Answer 2

The sound intensity is  $1*10^{-2.4} W/m^{2}$ and $1*10^{-2.6} W/m^{2}$

Loudness of sound :

The relationship between loudness and sound intensity is given as,

                             $\beta (dB)=10log_{10}(\frac{I} {I_{0}} )$

Where I is sound of intensity and $\beta$ is loudness of sound.

Given that,  $\beta=96dB,I_{0}=10^{-12} W/m^{2}$

Substitute values in above relationship.

                  $96=10log_{10}(\frac{I} {10^{-12} } )\\\\log_{10}(\frac{I} {10^{-12} } )=9.6\\\\\frac{I} {10^{-12} }=10^{9.6} \\\\I=10^{9.6}*10^{-12}=1*10^{-2.4} W/m^{2}$

The sound intensity is  $1*10^{-2.4} W/m^{2}$ and $1*10^{-2.6} W/m^{2}$
