The Decibel (dB) Scale & Audio Rules 101 | Audioholics

One of the most important concepts in audio is the decibel, the unit of measure denoting the ratio of a change in level, whether that level is acoustic Sound Pressure Level (SPL) or electrical signal level. It’s abbreviated dB. As you may or may not be aware, the decibel (dB) scale is a logarithmic system, as opposed to a linear scale.
dB: What is a decibel?

sound level = 20 log (pmeasured/pref) = 20 log 1 = 0 dB. Remember that decibels measure a ratio. 0 dB occurs when you take the log of a ratio of 1 (log 1 = 0). So 0 dB does not mean no sound, it means a sound level where the sound pressure is equal to that of the reference level.

Sound is measured in units called decibels (dB). The higher the decibel level, the louder the noise. On the decibel scale, the level increase of 10 means that a sound is actually 10 times more intense, or powerful.

What is a decibel and what does it measure?
https://www.healthyhearing.com/report/52514-What-is-a-decibel
Amplitude, reported on the decibel (dB) scale, measures sound's pressure or forcefulness. The more amplitude a sound has, the louder it is. In daily life, we often think of this as volume. Decibels increase exponentially 'A 10 db increase means 10 times louder, a 20 db increase means 100 times louder' Decibels are measured logarithmically.

Decibel (dB) definition. 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. The logarithmic scale can describe very big or very small numbers with shorter notation. The dB level can be viewed as relative gain of one level vs. other level, or absolute logarithmic scale level for well …

In the May AudioFile newsletter, I described the subjective sense of loudness changes that increases of 1 dB (just barely detectable change in loudness), 3 dB (slightly louder), or 10 dB (twice as loud) trigger in average listeners. On your AV receiver, the dB indications are still relative and you should hear them that way.
