We discussed this in another thread recently with our friendly local acoustics engineer (Coldkiwi). The measurable power level in a pressure wave goes up logarithmically (specifically, a 3dB differential indicates twice (or half) the power level) but our aural perception is linear on the same scale; 3dB is close to the minimum possible difference that the human ear can detect.
In other words, when something sounds 'twice as loud', the energy in the compression waves assaulting your eardrums is actually several orders of magnitude greater.
kiwibiker is full of love, an disrespect.
