The level of −3 dB is equivalent to 70.7% (factor = 0.7071), and the level of −6 dB is equivalent to 50% (factor = 1/2 = 0.5) of the initial voltage. This applies to the field quantity voltage or sound pressure. The level of the output power level is 0 dB, that is 100% (factor or ratio = 1).

The Decibel (dB) Scale & Audio Rules 101 | Audioholics
https://www.audioholics.com/room-acoustics/the-decibel-db
One of the most important concepts in audio is the decibel, the unit of measure denoting the ratio of a change in level, whether that level is acoustic Sound Pressure Level (SPL) or electrical signal level. It’s abbreviated dB. As you may or may not be aware, the decibel (dB) scale is a logarithmic system, as opposed to a linear scale.

To get x you do 10^ (.1/20) = 1.01158. From x dB to ratio (amplitude): 10^ (x/20) From x ratio (amplitude) to dB: 20Log10 (x) If you can calculate the ratio, then you should be able to calculate the correction needed, round to the next .1dB step, and apply it in one step.

Nonlinear distortions are given as distortion attenuation a k in dB or as damping factor k (THD) in percent. Total harmonic distortion (THD) is defined as the ratio of the rms voltage of the harmonics to that of the fundamental component. This is accomplished by using a spectrum analyzer to obtain the level of each harmonic and performing an rms summation.

signal processing - How can I calculate audio dB level ...
https://stackoverflow.com/questions/2445756/how-can-i-calculate-audio-db-level
calculate noise level = 20 * log10 (V_noise / V_ref) + dB_ref. Of course this assumes that the frequency response of your microphone and audio hardware is reasonably flat and that you just want a flat (unweighted) noise figure. If you want a weighted (e.g. A-weight) noise figure then you'll have to do rather more processing.
