http://www.sengpielaudio.com/calculator-amplification.htm
The dB value is positive. (+) V 2 < V 1 or V out < V in means damping. The dB value is negative. (−) V 2 / V 1 or V out / V in means the ratio. The amplification or the damping in dB is: L = 20 × log (voltage ratio V 2 / V 1) in dB. V 1 = V in is the reference.
The Decibel (dB) Scale & Audio Rules 101 | Audioholics

2 w = 89 dB 4 w = 92 dB 8 w = 95 dB 16 w = 98 dB 32 w = 101 dB 64 w = 104 dB 128 w = 107 dB 256 w = 110 dB As you can see, even relatively modest amplifiers can drive these speakers to healthy loudness levels in a normal room. The need for power escalates very quickly as you approach “lifelike” or “theater” levels of around 100-104 dB.

dB = 20 * log10 (amplitude) The amplitude in this case is expressed as a number between 0 and 1, where 1 represents the maximum amplitude in the sound file. For example, if you have a 16 bit sound file, the amplitude can go as high as 32767. So you just divide the sample by 32767. (We work with absolute values, positive numbers only.)

Formulas: To convert a ratio to dB, do log and then times by 10. Example: ratio = 1234 times. Log (1234) = 3.09. Ten times 3.09 = 30.9 dB. To convert dB to ratio, divide by 10 and then do ten to the x, like 10 x. Example: dB = +12.5 dB. Divide +12.5 by 10 = +1.25. Do 10 1.25 = 17.8 ratio.

This audio tools provides a quick and convenient means to convert between them. dBV refers to a voltage magnitude referenced to 1 volt, while dBu is referenced to 0.775 volts. Essential Formulas dBV = dBu - 2.21 Volts = 10 (dBu / 20) x 0.775 dBu = dBV + 2.21 Volts = 10 (dBV/20) dBu = 20 log (Volts/0.775) dBV = 20 log (Volts)
