Interesting! Are we talking about trained listeners? Or are we talking about off-the-street-college-kids-and-Joe-the-plumber type listeners?
And what sort of listening impressions are we considering as having value? I have always considered descriptions referenced to measurements to have some validity. But I have always considered impressions (and resulting descriptions) such as " .... "bright", "hollow", "dry", "forward", "tubby" and "loose", "incisive" and "warm" as having no value, simply because no two people define them the same way nor hear them the same way.
So my curiosity is definitely piqued
; what sort of subjective listening impressions support an analysis that provides statistically-supported and useful data?
