The Level of a Sound in Decibels Is Calculated Using $D = 10 \cdot \log \left( I \times 10 ^ { 12 } \right)$

question 68

Short Answer

The level of a sound in decibels is calculated using the formula $D = 10 \cdot \log \left( I \times 10 ^ { 12 } \right)$ where I is the intensity of the sound waves in watts per square meter. The sound intensity inside a typical car at 60 mph is 0.00001 watts per square meter. How many decibels is that?
