QuestionThe loudness, $L$, measured in decibels (Db), of a sound intensity, $I$, measured in watts per square meter, is defined as $L=10 \log \frac{1}{i_{0}}$, where $\rho_{0}=10^{-12}$ and is the least intense sound a human ear can hear. What is the approximate loudness of a rock concert with a sound intensity of $10^{-1}$ ? 2 Db 22 Db 60 Db 110 Db
