question 98

Multiple Choice

A certain noise has an intensity I of $9.61 \times 10 ^ { - 5 }$ . Given that decibel level D is related to intensity by $\mathrm { D } = 10 \log \left( \frac { \mathrm { I } } { \mathrm { I } } \right)$ , where $\mathrm { I } _ { 0 }$ is $10 ^ { - 12 }$ , determine the decibel level of the noise. Round your answer to the nearest decibel.

• A) 184 decibels
• B) 8 decibels
• C) 70 decibels
• D) 80 decibels
