Headphones and earbuds can emit a maximum sound from 85 to 110 decibels, levels that could lead to hearing loss, Foy said. Foy recommends following the “60/60 rule.” If your device has a volume range of 1 to 10, the highest listening level should be no more than 6 — 60 percent of the volume range.
Is 70 dB safe for headphones?
Sound less than 70 dB is unlikely to cause any significant damage to the ears. This is important to know, because the maximum volume of personal listening devices is above the threshold at which damage occurs (in both children and adults)!

3dB rule when measuring noise at work When you measure noise levels with a noise meter, you measure the intensity of noise in units called decibels, expressed as dB(A). It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value.
What does the volume limit on Apple earbuds do?

The actual sound pressure level that you experience depends on several factors: the music you’re listening to, how it was recorded and encoded, the type of earbuds or headphones you use, and their placement in your ears.
What should the output impedance of a headphone be?
