"WebBecause the decibel scale is a logarithmic one, doubling the gain does not double the decibel value. A gain of 16, for example, is equivalent to 12 . dB, not 18 dB.. Multiplying gain by 100, to make it 800, increases the decibel rating only to 29 dB.Although this scale is difficult to comprehend at first, it is a useful one for the audio designer.
