Abstract
Because the intrinsic muscles of the larynx determine vocal fold posturing in phonation, a model of vocal fold posturing requires data from the passive and active viscoelastic properties of these intrinsic muscles. Using reported one-dimensional active (twitch and tetanus) and passive muscle (step elongation and relaxation) measures from fresh excised canine laryngeal muscles, one-dimensional first-order Kelvin model parameters were obtained. Obtaining these parameters was accomplished through optimization, where force-elongation patterns predicted by the model were compared to measured muscular passive cyclic force-elongation patterns. These parameters are reported along with the design for the Kelvin model. The results of this study, which will be integrated into a larger finite-element posturing model, become the first step in predicting the vocal fold configurations needed for phonation.
