The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 10 1/10 (approximately 1.26) or root-power ratio of 10 1/20 (approximately 1.12).
The decibel (dB) is a unit that expresses the ratio of two values of a physical quantity, often power or intensity. One decibel is one-tenth of one bel, a unit named in honour of Alexander Graham Bell.
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.
The unit for measuring the relative intensities of sound is called a decibel. Because the decibel scale is logarithmic, a sound with an intensity that is twice that of a reference sound corresponds to an increase of little more than 3 decibels.
Sep 7, 2023 · Decibels (abbreviated dB) are the units used to measure the relative intensity of a sound. The decibel unit of measurement is a little odd because the human ear is incredibly sensitive. The human ear can hear everything from your fingertip brushing lightly over your skin to a loud jet engine.
Decibel (Symbol: dB) is a logarithmic unit that indicates ratio or gain. Decibel is used to indicate the level of acoustic waves and electronic signals. The logarithmic scale can describe very big or very small numbers with shorter notation.
Definition and examples The decibel (dB) is a logarithmic unit used to measure sound level. It is also widely used in electronics, signals and communication. The dB is a logarithmic way of describing a ratio. The ratio may be power, sound pressure, voltage or intensity or several other things.
a unit for measuring the loudness of sound. (Definition of decibel from the Cambridge Academic Content Dictionary © Cambridge University Press) Examples of decibel. decibel. Oh, and also the guy over at the squat rack, grunting at a decibel level somewhere between train whistle and snowmobile.
Decibel definition: a unit used to express the intensity of a sound wave, equal to 20 times the common logarithm of the ratio of the pressure produced by the sound wave to a reference pressure, usually 0.0002 microbar.. See examples of DECIBEL used in a sentence.
