Anyway, using decibels for sound works really nicely in another way as well: humans largely perceive sound on a logarithmic scale. A sound that's 60 dBI loud feels twice as loud as a 30 dBI sound, even though it's 1,000 times as intense.

If you double the gain of your amp in logarithm space, you're squaring the intensity, but it feels right to think of that as "twice as loud."
