A Certain Noise Has an Intensity $I$ Of $1.91 \times 10^{-5}$ Given That Decibel Level

Multiple Choice

A certain noise has an intensity $I$ of $1.91 \times 10^{-5}$ . Given that decibel level $D$ is related to intensity by $\mathrm{D}=10 \log \left(\frac{\mathrm{I}}{\mathrm{I}_{\mathrm{O}}}\right)$ , where $\mathrm{I}_{\mathrm{O}}$ is $10^{-12}$ , determine the decibel level of the noise. Round your answer to the nearest decibel.

A) 7 decibels
B) 63 decibels
C) 168 decibels
D) 73 decibels
