WebWhen the logarithm used is base ten, the SI unit is the bel (B). Although the bel is computed from quantities with units, the bel is itself unitless. The bel is too big for most purposes so the decibel (dB) is more common. 1 bel = 10 decibel. A level increase of 3 dB is approximately equal to a doubling of intensity (since log 2 ≈ 0.3).
