Question
A certain sound level is increased by $20 \mathrm{dB}$. By what factor does itsintensity increase?(A) 2(B) 20(C) $\quad 100$(D) $\quad \log 2$
Step 1
This equation is given by: \[ \beta = \beta_{0} + 10 \log \left(\frac{I}{I_{0}}\right) \] where $\beta$ is the sound level, $\beta_{0}$ is the initial sound level, $I$ is the final intensity, and $I_{0}$ is the initial intensity. Show more…
