Solve the problem.
-A certain noise produces $3.89 \times 10 ^ { - 4 }$ Watts $/ \mathrm { m } ^ { 2 }$ of power. What is the decibel level of this noise? The level of sound intensity in decibels $( \mathrm { dB } )$ is $\beta = 10 \log \left( \frac { \mathrm { I } } { \mathrm { I } } \right)$, where $\beta$ (beta) is the number of decibels, I is the sound intensity in $\mathrm { W } / \mathrm { m } ^ { 2 }$, and $\mathrm { I } _ { 0 } = 10 ^ { - 12 } \mathrm {~W} / \mathrm { m } ^ { 2 }$. (Round to the nearest decibel.)
A) 76 decibels
B) 198 decibels
C) 9 decibels
D) 86 decibels
