There are a lot of different kinds of "dB's":

dB - plain old power ratio.
dBa - adjusted decibels
dBc - referred to a carrier.
dBd - gain of an antenna
dBi - another gain of an antenna
dBk - dB relative to 1000 Watts
dBm - obscure reference level, often used by military types.
dBm0 - refered to zero transmission level (in dBm)
dBmp - dB measured with psophometer weighting.
dBmr - dB title for men.
dbmV - Very useful CATV reference level, in wide usage.
dBrap - Relative power levels of RAP music songs.
dBrn - dB used by registered nurses.
dBrnc - dB's used by the Republicans?
dBV - Output voltage, referred to 1 V input.
dBW - dB referred to 1 Watt
dBx - Output level, relative to an *unknown* input level.

(I may have gotten some of the above definitions wrong.)
