The symbol for decibel is dB. Always lowercase d and capital B.

Actually, the decibel is the ratio between two power levels and is used for electrical signals also, not just sound. A 10dB increase means 10 times the power level, or 3.16 times the intensity (3.16 = square root of 10). 1dB is 0.1 Bels.
