This description is independent of the load on the ME (cochlea or ear canal) and holds in either direction: forward (from ear canal to cochlea) or reverse (from cochlea to ear canal). A transmission matrix describing ME function in chinchilla, an animal commonly used in auditory research, is presented, computed from measurements of forward ME function: input admittance YTM, ME pressure gain GMEP, ME velocity transfer function HV, and cochlear input admittance YC, in the same set of ears [Ravicz and Rosowski (2012b). J. Acoust. Soc. Am. 132, 2437\u20132454; (2013a). J. Acoust. Soc. Am. 133, 2208\u20132223; (2013b). J. Acoust. Soc. Am. 134, 2852\u20132865]. Unlike previous estimates, these computations require no assumptions about the state of the inner ear, effectiveness of ME manipulations, or measurements of sound transmission in the reverse direction. These element values are generally consistent with physical constraints and the anatomical ME \u201ctransformer ratio.\u201d Differences from a previous estimate in chinchilla [Songer and Rosowski (2007). J. Acoust. Soc. Am. 122, 932\u2013942] may be due to a difference in ME flexibility between the two subject groups.<\/jats:p>","DOI":"10.1121\/1.4982925","type":"journal-article","created":{"date-parts":[[2017,5,17]],"date-time":"2017-05-17T14:55:16Z","timestamp":1495032916000},"page":"3274-3290","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":5,"title":["Chinchilla middle ear transmission matrix model and middle-ear flexibility"],"prefix":"10.1121","volume":"141","author":[{"given":"Michael E.","family":"Ravicz","sequence":"first","affiliation":[{"name":"Eaton-Peabody Laboratory , Massachusetts Eye & Ear Infirmary, 243 Charles Street, Boston, Massachusetts 02114, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John J.","family":"Rosowski","sequence":"additional","affiliation":[{"name":"Eaton-Peabody Laboratory , Massachusetts Eye & Ear Infirmary, 243 Charles Street, Boston, Massachusetts 02114, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2017,5,17]]},"reference":[{"key":"2023071700241993400_c1","doi-asserted-by":"publisher","first-page":"1326","DOI":"10.1002\/dvdy.20666","article-title":"Joint formation in the middle ear: Lessons from the mouse and guinea pig","volume":"235","year":"2006","journal-title":"Devel.
