WebDecibels are logarithmic, not linear. For example, 20 dB is not twice the power ratio of 10 dB. The defining equation for decibels is A = 10*log10(P2/P1) (dB) where P1 is the power being measured, and P1 is the reference to which P2 is being compared. To convert from decibel measure back to power ratio: P2/P1 = 10^(A/10)
