Both a symmetric glottis (obliquity of 0 degrees) and a slanted glottis (obliquity of 20 degrees) were used. The oblique glottis (i.e., a glottis that slants relative to the axial tracheal flow) is present in both normal and abnormal phonation. Obliquity has been shown to create unequal cross-channel pressures on the vocal fold surfaces [Scherer et al., J. Acoust. Soc. Am. 109, 1616 (2001)], and the study here continues this line of research. For the oblique glottis, one side was divergent and the other convergent. Transglottal pressures from 3 to 15 cm H2O using constant airflows were used. Results indicated that the pressure distributions on the two sides of the glottis were essentially equal for the symmetric uniform case (pressures differed slightly near the exit due to asymmetric flow downstream of the glottis). For the oblique glottis, the pressures on the vocal fold surfaces at glottal entry differed by 21.4% of the transglottal pressure, suggesting that this oblique glottis creates upstream glottal pressures that may influence out-of-phase motion of the two vocal folds.<\/jats:p>","DOI":"10.1121\/1.1504849","type":"journal-article","created":{"date-parts":[[2002,10,7]],"date-time":"2002-10-07T20:59:25Z","timestamp":1034024365000},"page":"1253-1256","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":45,"title":["Intraglottal pressure distributions for a symmetric and oblique glottis with a uniform duct (L)"],"prefix":"10.1121","volume":"112","author":[{"given":"Ronald C.","family":"Scherer","sequence":"first","affiliation":[{"name":"Department of Communication Disorders, Bowling Green State University, 200 Health Center, Bowling Green, Ohio\u200943402"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daoud","family":"Shinwari","sequence":"additional","affiliation":[{"name":"Department of Communication Disorders, Bowling Green State University, 200 Health Center, Bowling Green, Ohio\u200943402"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth J.","family":"De Witt","sequence":"additional","affiliation":[{"name":"Department of Communication Disorders, Bowling Green State University, 200 Health Center, Bowling Green, Ohio\u200943402"},{"name":"Chemical Engineering, University of Toledo, 3060 Nitschke Hall, Toledo, Ohio\u200943606-3390"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Mechanical, Industrial, and Manufacturing Engineering, University of Toledo, 4006D Nitschke Hall, Toledo, Ohio\u200943606-3390"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bogdan R.","family":"Kucinschi","sequence":"additional","affiliation":[{"name":"Mechanical, Industrial, and Manufacturing Engineering, University of Toledo, 4006D Nitschke Hall, Toledo, Ohio\u200943606-3390"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdollah A.","family":"Afjeh","sequence":"additional","affiliation":[{"name":"Mechanical, Industrial, and Manufacturing Engineering, University of Toledo, 4006D Nitschke Hall, Toledo, Ohio\u200943606-3390"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2002,9,27]]},"reference":[{"issue":"1","key":"2023071406252235100_che78","doi-asserted-by":"crossref","first-page":"13","DOI":"10.1017\/S0022112078000026","article-title":"Asymmetric flows and instabilities in symmetric ducts with sudden expansions","volume":"84","year":"1978","journal-title":"J.
