    Sound intensity

    B=log(\frac{I}{I_{0}})

    If B=58.4 dB and I_{0}=10^{-12} \frac{W}{m^2}

    then:

    58.4=log(\frac{I}{10^{-12}})

    log(I/

    If you are wanting to know  I it is as follows:

     58.5=log(\frac{I}{10^{-12}})

     10^{58.5}=\frac{I}{10^{-12}}

     I=3.16 \times 10^{46}
