Describing the voltage gain of an amplifier that produces an output voltage of 3.5V for an input of 35mV as being 40dB, is equivalent to saying that the output voltage is 100 times greater than the input voltage. To reverse the process, and convert dBs to a voltage ratios for example, use:

Every 6dB of gain equates to a doubling of voltage; as such, a hypothetical amplifier with a voltage gain of 30dB will increase voltage by 2^5, or by a factor of 32. For unbalanced inputs, the THX standard gain level is 29dB; utilizing balanced inputs decreases this to 23dB, though naturally the output of the preamp is boosted by 6dB under this scenario (i.e. voltage output of the preamp …
The Decibel (dB) Scale & Audio Rules 101 | Audioholics
https://www.audioholics.com/room-acoustics/the-decibel-db
Rule #1: +3dB = 2x the amplifier power; +10dB = 10x the amplifier power. Going from 1 watt to 2 watts of amplifier power gains 3dB of additional output; that's a pretty good deal right? Again, going from 2 watts of amplifier power to 4 watts gains an additional 3dB of output.

The amplification or the damping in dB is: L= 20 × log (voltage ratio V2/ V1)in dB. V1= Vinis the reference. In physics, attenuation is regarded as a positive value. This naturally leads to sign errors when entering numbers. 3 dB ≡ 1.414 times the voltage (−)3 dB ≡ damping to the value 0.707 6 dB ≡ 2 times the voltage

Suppose one amplifier has gain of 3 and another has 5 and these two amplifiers are connected in cascaded manner. Overall gain of the system is 3 × 5 = 15. Now in logarithmic or dB scale these gain are 10 log3 = 4.77 dB and 10 log 5 = 6.99 dB respectively. In decibel scale this overall gain is 10 log15 = 11.76 dB which is nothing but 4.77 + 6.99.

amplifier. 1.3 Gain Setting for the Audio Power Amplifier It is also imperative to understand that the output signal from the CODEC or DAC driving the audio power amplifier should be as large as possible, to have a high SNR. Conversely, the gain of the audio power amplifier is set as low as possible. If the audio power amplifier’s gain is set

If you tune with a -3 db rating and play that particular song recorded with a +3db in the bass, the amp will be putting out 6db higher to the subs than you had intended. On the same note, it allows you to boost the bass more with the eq rather than using a bass boost on songs that are lacking in bass as well.
gain - What is 0 dB in digital audio? - Sound Design Stack ...

If the analog limit is 1V, in an 8 bit system it will get a sample value of 255, but in a 16 bit system it will get 65535. This make the choice rather obvious - the reference for dBFS should be the highest sample value of the system bit depth. So: dBFS = 20log (sample value / highest possible sample value)

Typical wideband amplifier design requires higher-order matching networks and more gain stages, both of which demand larger die area. The presented 8-stage amplifier uses a compact 'fishbone' layout technique, and its core size is as small as 190 × 123 μm 2. A small-signal gain of 15 dB at 160 GHz and a 3-dB bandwidth of 41 GHz are achieved.
