While self-consistent in derivation and application, block-type models of the vocal fold masses are inherently susceptible to non-physical aerodynamic loading conditions when vocal fold motion is highly asymmetric. A standard block-type model is compared against two modified models that disallow the non-physiological loading condition. These minor modifications toward a more physiologically relevant aerodynamic model alter the specific vibration regimes and prevalence of chaos, though bifurcations still exist.<\/jats:p>","DOI":"10.1121\/1.4790662","type":"journal-article","created":{"date-parts":[[2013,2,19]],"date-time":"2013-02-19T18:49:45Z","timestamp":1361299785000},"page":"EL214-EL220","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":5,"title":["The impact of glottal area discontinuities on block-type vocal fold models with asymmetric tissue properties"],"prefix":"10.1121","volume":"133","author":[{"given":"David E.","family":"Sommer","sequence":"first","affiliation":[{"name":"Department of Mechanical and Mechatronics Engineering, University of Waterloo , Waterloo, Ontario N2L 3G1, demsomme@uwaterloo.ca","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byron D.","family":"Erath","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aeronautical Engineering, Clarkson University , Potsdam, New York 13699 berath@clarkson.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mat\u00edas","family":"Za\u00f1artu","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Universidad T\u00e9cnica Federico Santa Mar\u00eda , Valparaiso, matias.zanartu@usm.cl","place":["Chile"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean D.","family":"Peterson","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Mechatronics Engineering, University of Waterloo , Waterloo, Ontario N2L 3G1, peterson@mme.uwaterloo.ca","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2013,2,19]]},"reference":[{"key":"2025080518012678700_c1","doi-asserted-by":"crossref","first-page":"1233","DOI":"10.1002\/j.1538-7305.1972.tb02651.x","article-title":"Synthesis of voice sounds from a two-mass model of the vocal cords","volume":"51","year":"1972","journal-title":"Bell Syst.
