The calculated airflow pressure is applied on the vocal fold as the driving force. The airflow region is then adjusted according to the calculated vocal fold displacement. The interaction between airflow and the vocal folds produces a self-oscillating solution. Lung pressures between 0.2 and 2.5kPa were used to drive this self-oscillating model. The spatial distribution of the impact pressure was studied. Studies revealed that the tissue collision during phonation produces a very large impact pressure which correlates with the lung pressure and glottal width. Larger lung pressure and a narrower glottal width increase the impact pressure. The impact pressure was found to be roughly the square root of lung pressure. In the inferior-superior direction, the maximum impact pressure is related to the narrowest glottis. In the anterior-posteriorfirection, the greatest impact pressure appears at the midpoint of the vocal fold. The match between our numerical simulations and clinical observations suggests that this self-oscillating finite-element model might be valuable for predicting mechanical trauma of the vocal folds.<\/jats:p>","DOI":"10.1121\/1.2197798","type":"journal-article","created":{"date-parts":[[2006,6,12]],"date-time":"2006-06-12T16:13:01Z","timestamp":1150128781000},"page":"3987-3994","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":64,"title":["Simulation of vocal fold impact pressures with a self-oscillating finite-element model"],"prefix":"10.1121","volume":"119","author":[{"given":"Chao","family":"Tao","sequence":"first","affiliation":[{"name":"University of Wisconsin Medical School Department of Surgery, Division of Otolaryngology Head and Neck Surgery, , Madison, Wisconsin 53792-7375"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jack J.","family":"Jiang","sequence":"additional","affiliation":[{"name":"University of Wisconsin Medical School Department of Surgery, Division of Otolaryngology Head and Neck Surgery, , Madison, Wisconsin 53792-7375"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Zhang","sequence":"additional","affiliation":[{"name":"University of Wisconsin Medical School Department of Surgery, Division of Otolaryngology Head and Neck Surgery, , Madison, Wisconsin 53792-7375"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023071321353785100_c1","doi-asserted-by":"publisher","first-page":"511","DOI":"10.1121\/1.396829","article-title":"Glottal air-flow and transglottal air-pressure measurements for male and female speakers in soft, normal, and loud voice","volume":"84","year":"1988","journal-title":"J.
