Flow-induced oscillations of vocal-fold replicas with tuned extensibility and material properties by Paul Luizard, Lucie Bailly, Hamid Yousefi-Mashouf, Raphaël Girault, Laurent Orgéas, Nathalie Henrich Bernardoni

“…In particular, increasing the material stiffness increases glottal flow resistance, subglottal pressure required to sustain oscillations and vibratory fundamental frequency. In addition, although the hydrogel vocal folds only oscillate at low frequencies (close to 60 Hz), the subglottal pressure they require for that purpose is realistic (within the range 0.5–2 kPa), as well as their glottal opening and contact during a vibration cycle. …”
