dB?
dB is a logarithmic scale used to "measure" sound intensity. The standard reference, 1dB, is the quietest sound persons with normal hearing can detect.
The rule of thumb I learned was that for approximately 3dB change in volume, twice the power was needed, so, if a 50 watt amp put out 80 dB thru speaker "x", (measured with a sound meter)then 100watts would put out 83dB,200watts would put out 86 dB and so forth.
Most mixing boards have a 0dB line on the faders which indicates that the signal path is at an optimum value; signal below this line (-dB) will have more noise relative to the source, signal above this line may start to clip/distort.
