The shouted voice: a pilot study of the larynx physiology under extreme aerodynamic pressures
Résumé
Introduction: The objective was to study the behavior of the larynx during shouted voice production,when the larynx is exposed to extremely high subglottic pressure. Materials and methods: The study involved electroglottographic, acoustic, and aerodynamic analyses of shouts produced at maximum effort by three male participants. Results and discussion: Under a normal speaking voice, the voice sound pressure level (SPL) is proportional to the subglottic pressure. However, when the subglottic pressure reached high levels, the voice SPL reached a maximum value and then decreased as subglottic pressure increased further. Furthermore, the electroglottographic signal sometimes lost its periodicity during the shout, suggesting irregular vocal fold vibration.
