Jul 30, 2013 4) When levels in decibels are used, state the reference quantity for each kind of level when the level is introduced. Letters added to the decibel

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. Abbreviation: dB. See also perceived noise decibel.

Used to measure microphone sensitivity. dBμV or dBuV dB(μV RMS) – voltage relative to 1 μV. Widely used in TV and antenna amplifier specs. 60 dBμV = 0 dBmV The term dB (deciBel) and the dB scale are used world-wide for the measurement of sound levels. The deciBel scale is a logarithmic scale where a doubling of sound pressure corresponds to a 6 dB increase in level. It is important to realize that the term 'dB' can have different meanings and is not a fixed value like the volt or the meter etc.

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

dBm was all Decibel definition is - 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. As such, it proved to be inconveniently large, and the decibel, abbreviated dB, is the unit now in widespread use. The same power ratio expressed in decibels is. The decibel (dB) is a measure of the ratio between two quantities, and is used in a as it is an abbreviation of a name-derived unit, the bel, named for Alexander The values in column 4 of Table 4.1, measuring sound loudness in decibels, come from the following equation for decibels-sound-pressure-level, abbreviated Understanding dB - decibels explained. dB is an abbreviation for "decibel".
