An urban planning committee is evaluating the noise levels of a busy city street. Using the decibel level formula $D = 10 \log\left(\frac{I}{10^{-12}}\right)$, what is the decibel level ($D$) of heavy city traffic when the sound intensity $I$ is measured at ${}10^{-3}$ watts per square inch?

An environmental health officer is investigating noise pollution in a metropolitan area. To calculate the decibel level ($D$) of heavy city traffic with a sound intensity of $I = 10^{-3}$ watts per square inch, the officer uses the standard formula D = 10 \log\left(\frac{I}{10^{-12}} ight). Arrange the following steps in the correct order to complete the calculation as described in the course materials.

An urban planning team is conducting a noise assessment of city traffic. Match each component of their calculation with its correct numerical value based on the decibel formula $D = 10 \log\left(\frac{I}{10^{-12}}\right)$.

An urban planning technician is conducting a noise assessment near a busy intersection. If the heavy city traffic has a sound intensity of $I = 10^{-3}$ watts per square inch, then according to the standard formula $D = 10 \log\left(\frac{I}{10^{-12}}\right)$, the resulting noise level is 90 dB.

As a health and safety officer, you are reviewing a site assessment for a new office building near a busy intersection. The report indicates that the sound intensity ($I$) of the heavy city traffic is ${}10^{-3}$ watts per square inch. When applying the standard decibel formula $D = 10 \log\left(\frac{I}{10^{-12}}\right)$ as demonstrated in the lesson, the calculated noise level is ____ dB.
