Decibel är ett så kallat logaritmiskt mått, som mäter ljudnivåer. För att förklara hur en logaritmisk skala fungerar så är det enklast att ge några exempel.

Il decibel (simbolo ㏈) è la decima parte del bel (simbolo B): 10 ㏈ = 1 B ed è un'unità di misura logaritmica del rapporto fra due grandezze omogenee (es. due potenze, due pressioni, due potenziali elettrici). Definition of decibel. 1 a : a unit for expressing the ratio of two amounts of electric or acoustic signal power equal to 10 times the common logarithm of this ratio. b : a unit for expressing the ratio of the magnitudes of two electric voltages or currents or analogous acoustic quantities equal to 20 times the common logarithm of the voltage or 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.

1 a : a unit for expressing the ratio of two amounts of electric or acoustic signal power equal to 10 times the common logarithm of this ratio. b : a unit for expressing the ratio of the magnitudes of two electric voltages or currents or analogous acoustic quantities equal to 20 times the common logarithm of the voltage or The decibel (dB) is a logarithmic unit used to measure sound level. It is also widely used in electronics, signals and communication.

A decibel is one unit on the decibel scale, which is a logarithmic scale. The name means one-tenth of a bel, a bel being an eponymous unit named for Alexander Graham Bell and used to compare power in electrical communication, voltage, or intensity of sound. The abbreviation of bel is B …

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.

One bel is a power ratio of 10:1, and is divided into ten decibels. An increase of three decibels is approximately a doubling of power. Decibels are often used in measuring telecommunication signals. Decibel.

Enter the values in one or two of the text boxes and press the corresponding Convert button: Auto Decibel Database Decibel Addition and Subtraction Sound levels are generally expressed in decibels, which are logarithmic and so cannot be manipulated without being converted back to a linear scale. You must first antilog each number, add or subtract and then log them again in the following way: dB (decibel): A technique for expressing voltage,power, gain, loss, or frequency in logarithmic form against a reference.Typical references include volts, watts or Hz. DeciBels are calculated using the expression: Level in decibel L = 20 × log (x/y) or I 2 = dB You can explore numerically to confirm that doubling the distance drops the intensity by about 6 dB and that 10 times the distance drops the intensity by 20 dB. Decibel definition dBm or dB mW (decibel-milliwatts) is a unit of level used to indicate that a power level is expressed in decibels (dB) with reference to one milliwatt (mW).

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 decibel (dB) is a unit of measurement for sound.
