Development and use of an anechoic subglottal tract for excised larynx experiments
Original language description
During phonation, both the supraglottal and subglottal tracts can have an influence on vocal fold vibrations. 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 using a loudspeaker and a microphone placed at its open end. This response was then 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.
