Loudness, a subjective measure, is often confused with objective measures of sound pressure such as decibels or sound intensity. Filters such as A-weighting attempt to adjust sound measurements to correspond to loudness as perceived by the average human. However, true perceived loudness varies from person to person and cannot be measured this way.
Sound Pressure Level, dynamic range and loudness are not the same. If everyone understood this then there would be no loudness war.

for example if you take two different cds(or a cd and a vinyl) put them at your cdjs,adjust gain,fader,eq to be exactly the same,you will notice that most
probably one sounds louder than the other (if they are not both brick walled at 0db)
that's way the dj has to take care of the gain at his mixer's input channels
THIS is the "loudness" we talk about

But it isn't actually loudness and the DJ will adjust the input trim to get unity on their channel meter anyway, regardless of the dynamic range or crest factor or RMS relation to 0dBFS.
Your argument assumes that the gain will remain the same. It doesn't, that is why we have this "loudness war", because of this false assumption.
There is a volume control. People do use it.
Loudness is set by the end user. It really, really, really is. |
