The Decibel Scale Measures the Loudness of Sounds Based on the Intensity

Short Answer

The decibel scale measures the loudness of sounds based on the intensity of sound waves. Decibels can be calculated using the formula $D = 10 \log \left( \frac { I } { 10 ^ { - 12 } } \right)$ where I is the intensity of a sound wave in watts per meter. What is the intensity of a shout that registers 85 decibels? Round to six decimal places.
