Hilde45 said it better than i could..
It is a dynamic process of learning and experimenting and training between physical measures set of parameters and the ears/brain impression... It is psychoacoustics ...😊
If i must trust my ears/brain by definition if i want to tune my systems/room, i must also train and educate my ears/brain using various measurements isolated parameters to refine and correct my first senses impressions.
Then debates between subjectivists and objectivists crowds is non sense...Psychoacoustics say it all ...
