The mean acoustic impedance in the awake animal was found to be 747 acoustic ohms. The standard deviation was 171 acoustic ohms. Acoustic impedance measures were obtained under the influence of various doses of Diabutal. The results indicate that there in an increase in negative pressure in the middle ear and concommitant decrease in acoustic impedance following administration of this anesthetic. The magnitude of the change in acoustic impedance was dependent upon the dosage administered. In addition, various aspects of the chinchilla tympanogram are discussed.<\/jats:p>\n               <jats:p>Subject Classification: 65.24, 65.22.<\/jats:p>","DOI":"10.1121\/1.380775","type":"journal-article","created":{"date-parts":[[2005,10,3]],"date-time":"2005-10-03T22:15:11Z","timestamp":1128377711000},"page":"1100-1103","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["Static acoustic impedance of the chinchilla middle ear: Awake and sedated"],"prefix":"10.1121","volume":"58","author":[{"given":"Charles M.","family":"Woodford","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, State University of New York, Upstate Medical Center, Syracuse, New York 13210"},{"name":"Department of Mechanical and Aerospace Engineering, Syracuse University, Syracuse, New York 13210"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donald","family":"Henderson","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, State University of New York, Upstate Medical Center, Syracuse, New York 13210"},{"name":"Department of Mechanical and Aerospace Engineering, Syracuse University, Syracuse, New York 13210"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roger P.","family":"Hamernik","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, State University of New York, Upstate Medical Center, Syracuse, New York 13210"},{"name":"Department of Mechanical and Aerospace Engineering, Syracuse University, Syracuse, New York 13210"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan S.","family":"Feldman","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, State University of New York, Upstate Medical Center, Syracuse, New York 13210"},{"name":"Department of Mechanical and Aerospace Engineering, Syracuse University, Syracuse, New York 13210"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","container-title":["The Journal of the Acoustical Society of America"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/58\/5\/1100\/11376098\/1100_1_online.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/58\/5\/1100\/11376098\/1100_1_online.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,7,18]],"date-time":"2023-07-18T01:14:00Z","timestamp":1689642840000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/58\/5\/1100\/638531\/Static-acoustic-impedance-of-the-chinchilla-middle"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1975,11,1]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1975,11,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.380775","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1975,11]]},"published":{"date-parts":[[1975,11,1]]}}}
