Decibel is a mesurment where the amplitude or power is mesured in the inverse of exponetial, multiplied by 20 for amplitude relative to a reference level.
It's used when the grow is not linear.
Compute any given amplitude in the form of logarithmic Decibel (dB) using a value as reference.
Fill two of the three fields to compute the desired value, the reference, the referenced or dB (Decibel).
