dB: [ des´ĭ-bel ] a unit of relative power intensity equal to one tenth of a bel, used for electric or acoustic power measurements; one decibel equals approximately the smallest difference in acoustic power the human ear can detect and an increase of 10 decibels approximately doubles the loudness of a sound. Abbreviated dB or db. Examples of Bel is a measure of comparative power, or loudness, i.e., a unit of relative power ratio. The number of decibels is the decimal logarithm of the relative power ratio, which is expressed mathematically as follows: dB = 10 log 10 (P 1 /P 2) where dB = deciBel, P 1 is the power level to be measured, and P 2 is the reference power level. a similar unit for measuring the intensity of a sound. It is equal to ten times the logarithm to the base ten of the ratio of the intensity of the sound to be measured to the intensity of some reference sound, usually the lowest audible note of the same frequency.

2020. "Decibel".

The standard decibel abbreviation of dB is changed to dBm to indicate the use of the 1-milliwatt standard reference. Thus, a signal level of +3 dBm is 3 dB above 

The dB is a logarithmic way of describing a ratio. The ratio may be power, sound pressure, voltage or intensity or several other things. There are numerous dB abbreviations followed by letters. Here is a partial list of those widely used in electronics: dBV, dB(V RMS) – voltage relative to 1 V, regardless of impedance. Used to measure microphone sensitivity.

1 MSC corresponded to the loss of power over a 1 mile (approximately 1.6 km) length of standard telephone cable at a frequency of 5000 radians per second (795.8 Hz), and matched closely the smallest attenuation detectable Se hela listan på DECIBEL (dB) The Decibel is a subunit of a larger unit call ed the bel. As originally used, the bel represented the power ratio of 10 to 1 betwe en the strength or intensity i.e., power, of two sounds, and was named after Alexander Graham Bell. Thus a power ratio of 10:1 = 1 bel, 100:1 = 2 bels, and 1000:1 = 3 bels.
