What is bel in measurement?
Engineering. Bel (unit), a unit of measure equal to 10 decibels, named for Alexander Graham Bell.
What is bel physics?
(physics) A unit used for measuring sound intensity, equal to 10 decibels: abbrev. In other words, a unit of power ratio. The number of bels is the decimal logarithm of the power ratio, which is expressed mathematically as follows: B = log 10 (P 1 /P 2 ) where B = Bel, and P 1 and P 2 are power levels.
What does dB stand for in physics?
decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.
What decibel means?
What is Belbel and decibels?
Bel is the intensity level of a sound whose intensity is 10 times the standard intensity. One decibel is one-tenth of a Bel, i.e., 1 dB = 1/10 bel.
What is the meaning of Bel in physics?
In physics, bel – a measure of comparative power ratio, or relative loudness. In other words, a unit of power ratio. decibel – The decibel ( dB) is used to measure sound level, but it is also widely used in electronics, signals and communication.
What is the abbreviation for Decibel?
Alternative Title: dB. Decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.
What is the meaning of DB in physics?
The decibel (dB) is a unit used to express the ratio of two values of a physical quantity, often power or intensity. One decibel is one-tenth of one bel, a unit name named in honour of Alexander Graham Bell. This unit ‘ bel ‘ is seldom used. Decibel Meter.
