> 6 dB is twice as loud. Two violins are 3dB louder than one violin, 
it takes
> four to be twice as loud or 6 dB louder.


6dBm [or i think dBV] is twice as much SIGNAL
but twice as loud to the ear [accoustically] is 10dB spl

though of course the dB is not a fixed amount.
Noticable relative changes in level vary depending on the actual 
loudness and frequency. Actual loudness should be measured in phons 
and sones.
But who cares?
Most rock clients will notice it if they're song appears quieter than 
someone elses.
