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.

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 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.

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.
