However, other channels, such as the cochlear and vestibular aqueducts, may affect the fluid flow. To test if the OW and RW fluid flows are equal and of opposite phase, the volume displacement was assessed by multiple point measurement at the windows with a laser Doppler vibrometer. This was done during air conduction (AC) stimulation in seven fresh human temporal bones, and with bone conduction (BC) stimulation in eight temporal bones and one human cadaver head. With AC stimulation, the average volume displacement of the two windows is within 3 dB, and the phase difference is close to 180\u00b0 for the frequency range 0.1 to 10 kHz. With BC stimulation, the average volume displacement difference between the two windows is greater: below 2 kHz, the volume displacement at the RW is 5 to 15 dB greater than at the OW and above 2 kHz more fluid is displaced at the OW. With BC stimulation, lesions at the OW caused only minor changes of the fluid flow at the RW.<\/jats:p>","DOI":"10.1121\/1.1639903","type":"journal-article","created":{"date-parts":[[2004,2,3]],"date-time":"2004-02-03T16:07:45Z","timestamp":1075824465000},"page":"797-812","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":121,"title":["Fluid volume displacement at the oval and round windows with air and bone conduction stimulation"],"prefix":"10.1121","volume":"115","author":[{"given":"Stefan","family":"Stenfelt","sequence":"first","affiliation":[{"name":"Division of Otolaryngology\u2014Head and Neck Surgery, Stanford University Medical Center, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naohito","family":"Hato","sequence":"additional","affiliation":[{"name":"Division of Otolaryngology\u2014Head and Neck Surgery, Stanford University Medical Center, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard L.","family":"Goode","sequence":"additional","affiliation":[{"name":"Division of Otolaryngology\u2014Head and Neck Surgery, Stanford University Medical Center, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2004,1,30]]},"reference":[{"key":"2023071408080843500_aib01","doi-asserted-by":"crossref","first-page":"100","DOI":"10.1016\/S0378-5955(00)00240-9","article-title":"Human middle ear sound transfer function and cochlear input impedance","volume":"152","year":"2001","journal-title":"Hear.
