What are decibels a measure of?

Answer 1

The intensity of sound is measured in a unit called the decibel (dB), which describes the relative intensity of a sound based on an algorithmic decibel scale containing values ranging from 0 to 194.

A zero value on the decibel scale represents the weakest sound audible to humans and sound intensity increases in correspondence with numeric values, the relationship among the values on the decibel scale is not linear but algorithmic.

Here is an example of the decibel scale

Answer 2

Decibels is a ratio, e.g. the sound pressure of the threshold of hearing is 20µPa as the reference value that is 0 dB and the sound pressure 1 Pa is 94 dB. Everything can be measured in dB: The sound intensity, sound power, particle velocity, even the "loudness". Scroll down to related links and look at "How many decibels (dB) is twice ,double, half, or three times as loud?"

Answer 3

You measure two power levels by any convenient method for measuring power,

and then if you want to compare them in decibel units, you divide one by the other,

and find ten times the log of the quotient.

Answer 4

Decibel is a measure of the ratio of the strength of two signals, or two sound levels. It may also refers to the loudness of ONE sound, or the strength of ONE signal, with respect to a standard reference level.It is a logarithmic measure.

Answer 5

The property of intensity is measured in Decibels.(Db)

Answer 6

Decibels is a unit commonly used to measure the intensity of a sound.

Answer 7

They are a measure of the intensity or loudness of sound. It is a logarithmic scale, so that an increase of ten dB represents a doubling of the intensity.
