RE: Psychoacoustics is about correlating what we hear with what we measure

Easy, when listening to a subwoofer, people nearly always pick the one that "sound most like" a kick drum.
The problem is, a subwoofer is ONLY supposed to produce what comes out of the low pass crossover which is just the lowest parts of the drum.
The subwoofer with greater distortion and / or least low extension will sound most like the drum because it has a wider spectrum, even though it's not part of the input signal.
Another example, in recording tweaked electronics were used to add warmth (Beatles white album was the first one i knew of). Even harmonics are musically related and can add that warmth but is another non-linearity.
Now, what is the faithful reproduce is the issue and ears are not that reliable while a generation loss recording can make warts standout like soot on a white carpet.
