...of a ratio of 2 different amounts of power. A deciBel (that's 10 times a Bel in metric terminology) is 10 times the base-10 log of the ratio.The base-10 log of 2 is 0.301. Ten times that is 3.01, and that round to 3, so double the power is 3dB.
Do not confuse subjective expressions of twice as loud or half as loud with the very precise definition of deciBel. And as for 6dB, I've read elsewhere that many people require a change of about 10dB before they'll say a loudness is twice or half.
