The wind instrumentalist embouchure is probably one of the more demanding phenomena that occurs during their musical performance. It is important to quantify the forces that are applied during the wind instrumentalist embouchure on the perioral structures.
Quantify the pressures on the perioral structures involved during the embouchure mechanism of wind instrumentalists
Piezoresistive sensors of FlexiForceTM were placed on the mouthpiece of 30 different wind instrumentalists. During nine musical performances, the pressure applied on the mouthpiece was converted into a voltage output that was observed with a LabVIEW 2011 Carrier. Later the data was organized in tables of medium and maximum values for the different groups of wind instruments.
In ascending order of pressures registered the bassoon (6g-31g), the oboe (17g-125g), the saxophone (39g-120g), the clarinet (54g-106g), the trumpet, (63g-172g), the bisel flute (73g-245g), the French horn (56g-305g), the transversal flute (220g-305g) and the trombone (201g-325g).
Brass musicians seem to apply greater forces than woodwind musicians to realize the embouchure mechanism for the same music play. The piezoresistive sensors showed to be an accurate and non-invasive tool to quantify the embouchure pressures.
