Experimental and modelling study on the relationship between quality of the obtained sound and emission technique in the transverse flute
Thesis type EXPERIMENTAL AND SIMULATION
Description In the transverse flute the sound is produced thanks to the oscillation of the air jet (ejected by the player's mouth) upon entering the flute embouchure. These oscillations stimulate the air column inside the instrument that in turn produces the desired sound. It is common knowledge among experienced flute players that the air jet emission technique (in particular: velocity, pressure and temperature) strongly affects the quality of the obtained sound in terms of: cleanness (absence of turbulent noise), pitch of the fundamental harmonic and richness of the harmonic series. This common (and consolidated) knowledge is however purely qualitative, subjective and has never been the object of a rigorous scientific study. This thesis aims at performing a first analysis on the topic via experimental measurements (in anechoic chamber) understanding the relationship between produced sound and properties of the air jet ejected by the player's mouth. A computational analysis, based on computational fluid dynamics, is also possible.
