Solve the problem.
-Use the formula $L=10 \cdot \log \frac{I}{I_{0}}$, where the loudness of a sound in decibels is determined by $I$, the number of watts per square meter produced by the sound wave, and $\mathrm{I}_{0}=10^{-12}$ watts per square meter. A certain noise produces $5.34 \times 10^{-4}$ watts per square meter of power. What is the decibel level of this noise?
A) $77 \mathrm{db}$
B) $201 \mathrm{db}$
C) $9 \mathrm{db}$
D) $87 \mathrm{db}$
