Modeling vocal fold motion with a hydrodynamic semicontinuum model.
Vocal fold (VF) motion is a fundamental process in voice production, and is also a challenging problem for numerical computation because the VF dynamics depend on nonlinear coupling of air flow with the response of elastic channels (VF), which undergo opening and closing, and induce internal flow separation. The traditional modeling approach makes use of quasisteady flow approximation or Bernou...
متن کاملModeling Vocal Fold Motion with a New Hydrodynamic Semi-Continuum Model
Vocal fold (VF) motion is a fundamental process in voice production, and is also a challenging problem for direct numerical computation because the VF dynamics depend on nonlinear coupling of air flow with the response of elastic channels (VF), which undergo opening and closing, and induce internal flow separation. A traditional modeling approach makes use of steady flow approximation or Bernou...
متن کاملLaryngeal Electromyographic findings in patients with vocal fold motion asymmetry.
OBJECTIVES/HYPOTHESIS Vocal fold motion asymmetry (VFMA) is often attributed to vocal fold paresis or an anatomical variant. Although laryngeal electromyography (LEMG) may be used to evaluate patients with vocal fold paresis, electrodiagnostic findings in VFMA have not been well defined. STUDY DESIGN Review of a case series METHODS Twenty-five symptomatic patients with VFMA were examined by...
متن کاملA virtual trajectory model predicts differences in vocal fold kinematics in individuals with vocal hyperfunction.
A simple, one degree of freedom virtual trajectory model of vocal fold kinematics was developed to investigate whether kinematic features of vocal fold movement confirm increased muscle stiffness. Model simulations verified that increases in stiffness were associated with changes in kinematic parameters, suggesting that increases in gesture rate would affect kinematic features to a lesser degre...
متن کاملTowards an intermediate water wave model of vocal fold vibration: Evidence from vocal-fold dynamic sonography
A simplified water wave model was developed for predicting the global vibration of human vocal folds. As the depth of the liquids in the lamina propria is 1/2–1/20 of the wavelength, they were analogized to intermediate waters. The water wave model predicted elliptic orbits of the tissue particles with the major axis parallel to the surface, and these ellipses flattened with depth. This vibrati...
