Abstract

This study investigates the vibratory behavior of healthy and sulcus vocalis-affected vocal folds through a combined experimental and computational approach. Silicone vocal fold models with tunable mechanical properties are fabricated using a mold-based method. Finite Element Method (FEM) simulations reveal altered resonance patterns caused by sulcus pathology, particularly within the frequency range of 100–140 Hz. An experimental phonation setup employing chopper-modulated airflow and stroboscopic imaging captures the vibratory responses. Initial tests conducted with 15 kPa silicone confirm alterations in resonance modes, demonstrating the system’s potential for analyzing vocal fold disorders. ©2025 IEEE.
