Solve the problem.
-A certain noise produces $5.7 \times 10^{-4} \mathrm{watt} / \mathrm{m}^{2}$ of power. What is the decibel level of this noise (to nearest decibel)? Use the formula $\mathrm{D}=10 \log \left(\mathrm{S} / \mathrm{S}_{0}\right)$, where $\mathrm{S}_{0}=10^{-12}$ watt $/ \mathrm{m}^{2}$.
A) 88 decibels
B) 202 decibels
C) 78 decibels
D) 9 decibels

Quizplus · Accepted Answer

The decibel level is calculated as $ D = 10 \log \left( \frac{5.7 \times 10^{-4}}{10^{-12}} \right) $. This simplifies to $ D = 10 \log (5.7 \times 10^{8}) $, which is approximately 88 decibels.
