What means an objective improvement in sound ?
To some degree it is a measurable improvement by design improved numbers engineering and it must be also an acoustically measurable improvement then objective engineering improvement imply optimal acoustics environment ...
The problem is a subjective improvement must correspond to a psycho-acoustics improvement too ... Impaired hearings corrected by hearing aids are individually tailor made ...
Then some objective improvement may appear not an improvement for some needs and some specifically biased hearings, for some subjective values with their real objective manifestation and needs and history.
By the way i appreciate a lot all your posts .
Then objective improvement cannot be the only reason motivating wise upgrading ...![]()
«Hearing evolution in man was designed such by social survival circonstances to identify efficiently and immediately spoken words; to do this our ears/brain must have created their own non linear time working dimension, it is why acoustics imply an ecological perspective as the one given by Gibson for the eyes»--- Anonymus acoustician
As I said, what I was looking to explore in this thread is how an objective improvement in sound quality translates into subjective personal enjoyment. It’s the physicist in me that needs to examine our implicit and taken for granted assumptions.
