Effects on vocal fold collision and phonation threshold pressure of resonance tube phonation with tube end in water.
PURPOSE Resonance tube phonation in water (RTPW) or in air is a voice therapy method successfully used for treatment of several voice pathologies. Its effect on the voice has not been thoroughly studied. This investigation analyzes the effects of RTPW on collision and phonation threshold pressures (CTP and PTP), the lowest subglottal pressure needed for vocal fold collision and phonation, respe...
متن کاملPhonation threshold pressure and onset frequency in a two-layer physical model of the vocal folds.
The influence of vocal fold geometry and stiffness on phonation onset was experimentally investigated using a body-cover physical model of the vocal folds. Results showed that a lower phonation threshold pressure and phonation onset frequency can be achieved by reducing body-layer or cover-layer stiffness, reducing medial surface thickness, or increasing cover-layer depth. Increasing body-layer...
متن کاملPhonation threshold flow measurements in normal and pathological phonation.
OBJECTIVES/HYPOTHESIS Phonation threshold flow (PTF) may provide a tool to assess laryngeal function and could differentiate between normal and pathological voices. Both polyps and nodules contribute to an increased PTF by creating an incomplete glottal closure and increased vocal fold mass and thickness. STUDY DESIGN Prospective study. METHODS The Kay Elemetrics Phonatory Aerodynamic Syste...
متن کاملA Numerical and Analytical Study of Phonation Threshold Pressure and Experiments with a Physical Model of the Vocal Fold Mucosa
Lewis P. Fulcher, Advisor Titze (1988) used the surface wave model to derive an analytical expression for threshold pressure in terms of the glottal geometry and biomechanical parameters of the larynx. This formula was tested in a series of experiments in 1995 and 1997. Since the membrane of the physical model used in the experiments becomes rounded when a fluid flows beneath it, the effects of...
متن کاملA comparison of subglottal and intraoral pressure measurements during phonation.
Intraoral pressure and subglottal pressure, derived from tracheal puncture, were recorded with the electroglottographic signal for one normal speaking male during phonation. The mean subglottal pressure for vowels was also estimated by interpolating the intraoral pressure from surrounding /p/occlusions. The pressure measurements were highly correlated (r = 0.98) and there were small pressure va...
