Most articles on the subject, though, are addressed to engineers, by other engineers and producers fed up with the hammering their mixes receive at the hands of overzealous mastering engineers. For the average music consumer, the matter remains somewhat esoteric.
In his article Imperfect Sound Forever, Nick Southall addresses this, and more importantly why the steady increase in volume is so bad for consumers, from the perspective of someone who just loves music:
Levels have crept up over the last decade though, and alarmingly so. Nevermind is 6-8dB quieter than, say, Hopes & Fears by Keane—to contextualise this, those 6-8dB will make Nevermind sound approximately half as loud… Keane should NOT be twice as loud as Nirvana.
