a unit of relative power intensity used for acoustic or electric power; a change of one bel is a tenfold power increase and approximately doubles loudness of most sounds. See also decibel.

bel

(bel),
Unit expressing the relative intensity of a sound. The intensity in bels is the logarithm (to the base 10) of the ratio of the power of the sound to that of a reference sound. Ordinarily, the reference sound is assumed to be one with a power of 10-16 watts per sq cm, approximately the threshold of a normal human ear at 1000 Hz.

Acoustics
A unit expressing the logarithm of the ratio of power of a sound (P1) to that of a reference sound (P2)—i.e., log10P1/P2; in practice, the unit decibel is used.
