You miss an important part of the sentence in the second link: "The NIOSH Recommended Exposure Limit (REL) for occupational noise exposure is 85 decibels, A-weighted". dB expresses the ratio of one value to another. So without knowing what the other value is, it's rather meaningless. But it is unfortunately an often-made mistake: how many times haven't you heard or read just dB as such? Anyway, this means you cannot simply compare dB dynamic range with dB used to express sound pressure level of which 'A-Weighted' is just one standard which gets used. Those are completely different things. Simply said, you can play 96dB dynamic range music at sound pressure levels which you won't even hear. Or at sound pressure levels which damage your ears nearly instantly.
