### General formula for changing loudness in dB?

Posted:

**Wed Dec 05, 2018 8:53 pm**Hi,

I know enough audio to know that "twice as loud" is a 6 dB increase. If you add 6 dB on a fader, you have made that sound 2x as loud.

Can someone give me the right formula for calculating things like "X" as loud? Where X can be anything.

For example, a formula to calculate how many dB to add (or subtract) to make something 1.5x as loud. Or -1.7x as loud. Or any factor.

Thanks,

Fred
