The formula is 20 log (v-out / v-in) . V-in is the starting sound and V-out is the end. So 2 volts going in and 3 volts going out. 1.5 .... Log ... 0.176 ... x20 .... = 3.52dB. So that's what, 150% louder? 150% of 2 volts is 3 volts. There is a real-world problem with this process. 3.5dB is a barely...
