bel

 [bel]
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.
[A.G. Bell, Scottish-U.S. scientist, 1847-1922]

bel

(bel) a unit used to express the ratio of two powers, usually electric or acoustic powers; an increase of 1 bel in intensity approximately doubles loudness of most sounds. Symbol B. See also decibel.

bel

Etymology: Alexander G. Bell, Canadian inventor, 1847-1922
a unit that expresses intensity of sound. It is the logarithm (to the base 10) of the ratio of the power of any specific sound to the power of a reference sound. The most common reference sound has a power of 10-16 watts per square centimeter, or the approximate minimum intensity of sound at 1000 cycles per second that is perceptible to the human ear. An increase of 1 bel approximately doubles the intensity or loudness of most sounds. See also decibel.

bel

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.
