Since we are on the way to be correct and precise:

1) A decibel is not logarithm OF ratios of power.
2) A decibel is a decibel, in other words a number, independently if 
ratio of power, or voltages or whatsoever unity one likes to use. A 3 
dB, for example, is ten times the logaritm of the ratio of powers and 
20 times the logaritm of voltages.
3) Saying "2" I meant a generical S/N that's have infinite solutions 
beeing the ratio of two signals.  A 2 dB expresses infact an S that's 
1.6 times the noise power or 1.26 times the noise voltage (or current).
