Development and use of an anechoic subglottal tract for excised larynx experiments

Popis výsledku v původním jazyce

During phonation, both the supraglottal and subglottal tracts can have an influence on vocal fold vibrations and cause voice instabilities. This paper proposes a method to remove the influence of the two tracts on the vocal fold vibrations, which can be used in studies of inherent vibratory properties of the vocal folds. It uses excised larynges without a supraglottal tract and an anechoic (resonance-free) subglottal tract. The acoustic response of the developed anechoic subglottal tract was measured and compared with the response of a “resonant” subglottal tract with adjustable length. Both subglottal tracts were then explored in excised larynx experiments, where the subglottal pressure, radiated sound, and electroglottograph (EGG) signal were recorded.
