Decibel : What is dB and its importance for audio ...
https://magroove.com/blog/en-us/decibel/
And what not many people know is that a decibel is, in fact, the tenth part of a Bel (that’s why “deci”), a unit of measurement created by Bell Labs, telephony company owned by Graham Bell, to measure loss in transmission lines. But because in audio we measure in smaller scales, the “deci” was adopted for practical reasons.

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.

Enter the decibel The decibel (dB) is, in its purest form, a dimensionless unit that represents a ratio between two quantities, just like “×” or “%”. What sets the decibel apart is that it is also a logarithmic unit, meaning that its value is proportional to the logarithm of the ratio, not the ratio itself. This will be clearer with examples:

https://whatis.techtarget.com/definition/A-weighted-decibels-dBA-or-dBa-or-dBa
A-weighted decibels, abbreviated dBA, or dBa, or dB (a), are an expression of the relative loudness of sounds in air as perceived by the human ear. In the A-weighted system, the decibel values of sounds at low frequencies are reduced, compared with unweighted decibels, in which no correction is made for audio frequency.
