A Cervid Vocal Fold Model Suggests Greater Glottal Efficiency in Calling at High Frequencies
Figure 7
Efficiency measures across the phonation range of an elk/red deer larynx.
Six main parameters explaining the energy transfer at the laryngeal sound source and as they change with applied lung pressure. A: Peak glottal area, B: peak glottal airflow, C: aerodynamic glottal power, D: radiated sound intensity level. E: Radiated Power, F: Glottal efficiency.
