  • Analysis of vibratory characteristics, including onset pressure and motion patterns.

    • Main Results:

    • The multi-layer model demonstrated improved vibratory characteristics compared to one- and two-layer models.
    • Achieved onset pressures closer to those observed in human phonation.
    • Observed reduced inferior-superior motion and evidence of a mucosal wave.

    Conclusions:

    • The developed multi-layer synthetic vocal fold model offers a more realistic platform for voice production research.
    • This advancement has potential implications for understanding and treating voice disorders.
    • Further research with this model can enhance clinical prevention, diagnosis, and treatment strategies.
