The acoustical relevance of these flow structures to low-frequency voice production was evaluated by disturbing the supraglottal flow field using a cylinder and observing the consequence on the resulting sound pressure field. Despite a significantly altered supraglottal flow field due to the presence of the cylinder, only small changes in sound pressure amplitude and spectral shape were observed. The implications of the results on our understanding of phonation physics and modeling of phonation are discussed.<\/jats:p>","DOI":"10.1121\/1.3515838","type":"journal-article","created":{"date-parts":[[2011,1,11]],"date-time":"2011-01-11T13:55:56Z","timestamp":1294754156000},"page":"EL378-EL383","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":11,"title":["On the acoustical relevance of supraglottal flow structures to low-frequency voice production"],"prefix":"10.1121","volume":"128","author":[{"given":"Zhaoyan","family":"Zhang","sequence":"first","affiliation":[{"name":"University of California , Los Angeles School of Medicine, 31-24 Rehabilitation Center, 1000 Veteran Avenue, Los Angeles, California 90095\u20131794 zyzhang@ucla.edu , jneubauer@mednet.ucla.edu"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juergen","family":"Neubauer","sequence":"additional","affiliation":[{"name":"University of California , Los Angeles School of Medicine, 31-24 Rehabilitation Center, 1000 Veteran Avenue, Los Angeles, California 90095\u20131794 zyzhang@ucla.edu , jneubauer@mednet.ucla.edu"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2010,12,6]]},"reference":[{"key":"2025081417365054500_c1","doi-asserted-by":"crossref","first-page":"169","DOI":"10.1017\/S0022112096003382","article-title":"Further contributions on the two-dimensional flow in a sudden expansion","volume":"330","year":"1997","journal-title":"J.
