A Cervid Vocal Fold Model Suggests Greater Glottal Efficiency in Calling at High Frequencies
Figure 2
3-D FE model of the vocal folds.
A: Isolated vocal folds. B: Frontal section through the thyroid cartilage and the vibrating portion of the vocal folds shown in Figure 1, perpendicular to the fibers. The triangular element mesh was 12×14 elements for each of 5 layers along the fibers, or along the vocal fold length. Mucosa, ligament, and TA muscle are shown in color for the left vocal fold. The small inset about the larynx is the same top view of the vocal folds as in figure 1 indicating the cross section level with a dotted line.
