The model consisted of a vocal fold-shaped constriction situated in a rigid pipe coupled to a potential flow which separated at the superior edge of the vocal fold. The vocal fold constriction was modeled as a plane-strain linear elastic layer. The dominant eigenvalues and eigenmodes of the fluid-structure-interaction system were investigated as a function of glottal airflow. To investigate specific aerodynamic mechanisms of phonation onset, individual components of the glottal airflow (e.g., flow-induced stiffness, inertia, and damping) were systematically added to the driving force. The investigations suggested that flow-induced stiffness was the primary mechanism of phonation onset, involving the synchroniza-tion of two structural eigenmodes. Only under conditions of negligible structural damping and a restricted set of vocal fold geometries did flow-induced damping become the primary mechanism of phonation onset. However, for moderate to high structural damping and a more generalized set of vocal fold geometries, flow-induced stiffness remained the primary mechanism of phonation onset.<\/jats:p>","DOI":"10.1121\/1.2773949","type":"journal-article","created":{"date-parts":[[2007,9,26]],"date-time":"2007-09-26T22:21:15Z","timestamp":1190845275000},"page":"2279-2295","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":57,"title":["Physical mechanisms of phonation onset: A linear stability analysis of an aeroelastic continuum model of phonation"],"prefix":"10.1121","volume":"122","author":[{"given":"Zhaoyan","family":"Zhang","sequence":"first","affiliation":[{"name":"The Laryngeal Dynamics Laboratory , Division of Head and Neck Surgey, David Geffen School of Medicine at UCLA, 31-24 Rehabilitation Center, 1000 Veteran Ave., Los Angeles, California 90095-1794"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juergen","family":"Neubauer","sequence":"additional","affiliation":[{"name":"The Laryngeal Dynamics Laboratory , Division of Head and Neck Surgey, David Geffen School of Medicine at UCLA, 31-24 Rehabilitation Center, 1000 Veteran Ave., Los Angeles, California 90095-1794"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Berry","sequence":"additional","affiliation":[{"name":"The Laryngeal Dynamics Laboratory , Division of Head and Neck Surgey, David Geffen School of Medicine at UCLA, 31-24 Rehabilitation Center, 1000 Veteran Ave., Los Angeles, California 90095-1794"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023080405442016600_c1","doi-asserted-by":"publisher","first-page":"39","DOI":"10.1006\/jsvi.1995.0577","article-title":"Snoring: linear stability analysis and in-vitro experiments","volume":"188","year":"1995","journal-title":"J.
