A Comparative Study of Mongolian Folk Songs Based on the Breathing Signals of Physiological Mechanism

摘要

Through capturing the speech, chest and belly physiological signals of Mongolian folk short The song of Wining and Mongolian folk long Rich and vast la shan, this article designed and extracted related acoustic and physiological parameters. Taking breath cycle as an unit, this paper has analyzed chest and belly aspiration pattern of this folk song. Some conclusions were found: 1) The average breathing length of Mongolian folk long songs is longer than folk short songs; 2) The Breathing Signal's line of folk short songs is not smooth, and its boundaries between breathing unit is very fuzzy, its range is very large, and it has strong leap; The belly physiological signals of Mongolian folk long song is very obvious, Each boundaries between breathing unit is very clear, The breathing amplitude is very stable, and is not big; 3) Each breathing unit has a continuous period, the continuous period amplitude of Chest signals is large and the belly signals is small, That means singer is basically rely on the chest to breath in the process of singing, And the adjustment mechanism of the abdominal muscles is relatively weak; 4) About lasting duration, the trend of abdominal Lasting Duration signals of Mongolian folk short the songs and chest Lasting Duration signals is opposite. The results of this study provide physiological and acoustic methods for Mongolian folk song study and basic data for singing and protection as well.
