A Cervid Vocal Fold Model Suggests Greater Glottal Efficiency in Calling at High Frequencies
Figure 5
Iso-fundamental frequency contours for self-sustained vocal fold oscillation (solid lines, frequencies in Hertz, Hz) based on 175 simulations (Figure S2). They indicate where vocal fold oscillation can be maintained at a constant fundamental frequency near phonation threshold pressure, which is indicated in kPa on the right and top axis of the MAP. Iso-strain curves (dashed lines, strain ε) indicate the elongation of the vocal fold in order to achieve a certain tension of the oscillating tissue.
