The decibel (dB) is a unit that measures the intensity of sound, as well as the power level of electrical signals and other forms of energy. It is a logarithmic scale, meaning that an increase of 10 dB represents a tenfold increase in intensity or power. Decibels are commonly used in acoustics, telecommunications, and electronics to express ratios of power or intensity in a more manageable form.

What is the decibel a unit of?
Decibel is no real unit, it is a pseudo unit. The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity. A change in voltage ratio by a factor of two is approximately a 6 dB change. A change in power ratio by a factor of two is approximately a 3dB change.
Synonyms for the word decibel?
A tenth of a bel. It's a ratio of two values of the same unit.
What is one tenth of a bel?
A unit of power or intensity equal to one tenth of a bel is a decibel.
Is Decibel is the unit of power ratio?
It can be the power ratio. If you measure voltage or sound pressure it is not the power ratio.
What does the unit decibel measure?
The ratio between two quantities, usually quantities that somehow measure power, or intensity (power / area).

Is The decibel is a unit of pitch?
No. A decibel is one tenth of a bel. The decibel is a logarithmic unit of measurement that expresses the magnitude of a physical quantity relative to a specified reference level. It is a dimensionless unit, because it expresses a ratio of two quantities with the same unit.
