A decibel (dB) measures the intensity of sound and can help you understand the sound levels of your HVAC equipment.
With the new feature, Apple is putting more emphasis on the health dangers of being exposed to high volume audio. Listening to something at 80 decibels (dB) for more than 40 hours in a one-week period increases your risk of hearing loss. Raise it 10 dB to 90, and damage can begin af...

dBFS is decibels relative to the maximum output before clipping. Obviously 0 dBFS is therefore different for every single device. dB SPL is relative to 20 uPa. You can't compare something like dB SPL to something like dBu, since one is a pressure unit and...
Apple knows (but doesn't publicize) the figure for its headphones, so it can reasonably say that at X voltage, the result will by Y decibels, and it can be taken to be true. However, it cannot ensure that it will apply to all headphones; some will be more efficient than Appl...
