And let me add that psychoacoustics is not the same as
subjectivism -
you are correct in that they are not the same
but psychoacoustics does study the _subjective_ human perception of auditory phenomena
not the _objective_ human perception of auditory phenomena
and while there are acoustic phenomena common to all healthy hearing/neurology which can
be measured
you are glossing over two factors involved in psychoacoustics which render most scientific
generalization sort of dicey: emotional state and cultural bias
and anyway my post was referring to the claim that if a property of a mix can't be
scientifically measured then it doesn't exist -- which we all know is poppycock
because 'music mastering' is NOT a science - it is pure sonic voodoo
