On The Discussion Of Controllable Factor Of Piano Touching Technology Affecting Acoustical Quality Change

The researches of piano touching technology affecting acoustical quality change are mostly based on experiences and seldom on empirical literature. This paper aims at exploring the controllable factor of piano touching technology affecting acoustical quality change from the science perspective. It also takes the data analysis through touching velocity measurement experience and touching frequency spectrum analysis experience as well as explains the controllable factor of dynamics and speed during the process of piano touching technology affecting acoustical quality change. It also provides some empirical literature for the field research to some extent and systematically narrates the vague empirical formula, which is conducive to standardization and specialization of disciplinary knowledge.
