Using this logarithmic scale, a sound with an intensity of 20 decibels is 10 times more intense than a sound at 10 decibels. Likewise, a sound at 100 decibels is one billion times more intense ...

The decibel scale was created to quantify how loud sounds are. A difference of 1 dB is perceived as a minimum change in volume. A difference of 3 dB is a moderate change, ...

That’s because the decibel scale is logarithmic, not linear: With every 10 dB increase, the sense of loudness to the ear generally doubles.
