The Decibel (dB) Scale & Audio Rules 101 | Audioholics
https://www.audioholics.com/room-acoustics/the-decibel-db
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 Scale 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. Share this: Source 1, …

How to Read an Audiogram and Determine Degrees of Hearing Loss
https://www.nationalhearingtest.org/wordpress/?p=786
The decibel (or dB) is the unit of intensity used to describe hearing sensitivity. During a diagnostic hearing evaluation the threshold is measured at different frequencies (or Hertz, Hz) in each ear. The degree of hearing loss is expressed by the difference between a person’s threshold and the average threshold for people with normal sensitivity.

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.
+/-3 dB or -6 dB: What's the Difference? - ProSoundWeb

The purpose of this document is to explain the meaning of both specifications as they are commonly used (or misused) in pro audio today, and to provide a basis for comparing loudspeakers with differing stated specifications. The term “+/-3 dB” originally expressed flatness – not high and low frequency extension.

Simply, they refer to the voltage levels defined as 0 dBVU. Unbalanced The standard consumer “-10dBV” standard means that 0 dBVU equals -10 dBV, or, using the dB-to-volts formula: = 1V • 10 (-10/20) = 316.2 mV It so happens that this interface has been defined to carry 2V maximum (sine RMS, or 5.66 V P-P ).
What is the difference between 0 dB and 0 dBFS?
https://www.audiomasterclass.com/blog/what-is-the-difference-between-0-db-and-0-dbfs
A signal is a representation of that sound in either electronic or digital form. Differences in signal or sound levels are measured in decibels (dB). So a measurement of 10 dB means that one signal or sound is 10 decibels louder than another, or that a signal or sound has been made 10 decibels louder than it was before. 0 dB FREE TRIAL
