I can add to my point after the article i mention above about the aural memory this interesting french doctoral thesis titled :
Acoustic characterization of relationships between
biological movements and sound perception:
application to the control of synthesis and
learning gestures by Etienne Thoret
https://theses.hal.science/tel-01105122/document
There is no singular storage memory place in the body, it is not localized and not decoupled from the general set of gestures in our habit behaviour... We remember the best what we had learned to produce in our daily context or routine especially when associated with an emotional content experience ... ...
Then the difference between a device and his absence for a meaningful evaluation of his effect need a context which is not alien to our daily routine and interpretation context to be valuable, the opposite of what ideological objectivist ask for systematically for any small difference which is beyond ridiculous ...
It is why simple blind test in work specific stages in a personal journey work better than public double blind test on a stage theater ...
I did my work , i dont ask other people to put a show to make a point...
i trained my ears without the need to prove anything ... My acoustical musical experience is enough ...I dont sell products nor did i sell an ideology ...
