Dave, I have always seen this used for "micro", as in dBuV = decibel microvolts. It may also stand for decibel units. If so, a unit is most likely 1 volt rms, a common unit in professional audio. The formula would be 20 X LOG(input voltage/reference voltage), with LOG referring to LOG 10. Scott Lacey
