According to the $ ext{dB}$ scale logic, how much does the Sound Intensity Level ($ ext{SIL}$) increase when the physical sound intensity ($I$) doubles?
Answer
$3 ext{ dB}$
A two-fold increase in the measured physical intensity ($W/m^2$) results in an addition of only $3 ext{ dB}$ to the sound level, reflecting the logarithmic nature of the scale.
