I mentioned acoustic without (s) for years here...I forgot that in english the noun need an (s)... Written in the singular it is more an adjective and refer to "room acoustic" for example...
Witten with an (s) it refer to the science "acoustics"... It what was i meaned to say all these years... But many read me as if i was speaking merely on room acoustic...
Acoustics , the science INCLUDE psycho-acoustic and neuro-acoustic and not only material acoustic and great Hall acoustic architecture and small room acoustic control and design ...
The reason why audiophiles MUST STUDY acoustics concepts in general not only room acoustic is EVIDENT but rarely explained : No sound experience is understandable and describeable without these concepts... Most audio vocabulary refer to the gear system, for exemple "warm" and "cold" are associated to the gear alleged sound properties as with tubes or S.S. or dac and turntables, ( which is preposterous because all pieces of gear differ especially coupled in different conditions or modified ) instead of refering to the "timbre" experience" which cannot be understood anyway at all without understanding the 5 conditions defining timbre in acoustics and their control in a space....
Then most audiophiles as i am, begun to be open completely victim of marketing methods instead of being put on the road to understanding ... Gear had no sound in itself only specific potential characteristics manifested more or less , positively or negatively when coupled with other components and specific acoustic conditions ...
Tthe system /room had a sound quality and a synergy making it able to give some TIMBRE impressions ... The same is true for all spatial characteristic of sound and of immersiveness which is the relation between the sound source width and the listener envelopment... No gear possess these characteristics as claim marketing conditioning , only the specific system/room/ears as a whole , working in a specific room for specific ears/brain,...
