Understanding the 3dB rule - Pulsar Instruments
https://pulsarinstruments.com/news/understanding-3db-rule/
If the pin dropping has a sound level of 10dB (decibels) then two pins would have a level of 13dB. 10,000,000,000,000 pins would have a level of 140dB and 20,000,000,000,000 pins a level of 143dB. This 3dB rule is important to remember when you come to measure noise as well as analyse and predict individual exposure.

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

Every doubling of power is another +3dB of loudness. So: 2 w = 89 dB. 4 w = 92 dB. 8 w = 95 dB. 16 w = 98 dB. 32 w = 101 dB. 64 w = 104 dB. 128 w = 107 dB. 256 w = 110 dB. As you can see, even relatively modest amplifiers can drive these speakers to healthy loudness levels in a normal room.
How Much is a Decibel? Sound Perception Vs. Reality | …

Sound studies tell us time and again that a 3dBA increase in sound level is barely noticeable to the human ear. In fact, you have to raise a sound level by 5dBA before most listeners report a noticeable or significant change. Further, it takes a 10dBA increase before the average listener hears “double the sound.” That’s a far cry from 3dB.
+/-3 dB or -6 dB: What's the Difference? - ProSoundWeb

If the response of the loudspeaker is 3 dB lower at 50 Hz, the question “3 dB lower than what?” has to be answered. In this case, the answer appears to be “3 dB lower than 96 dB SPL.” But where did 96 dB SPL come from? 96 dB is 3 dB below the 99 dB nominal sensitivity of the loudspeaker.
How to Normalize Audio – What it is and Why You Need It
https://www.videoproc.com/audio-editor/normalize-audio.htm
If anything tends to go above the ceiling, it will be chopped off, resulting in audio distortion or clipping. dBFS is usually written as dB, as in 0bB, -3dB, -10 dB, etc. Rules of thumb: Audio levels must not exceed 0dB before exporting. If normalization is the last step, you can set it to 0dB, though -3dB to -6dB is recommended.
