To investigate infrasound propagation through the middle and inner ear, velocities of the stapes and round window membrane were measured to very low frequencies (down to 0.9\u2009Hz from 2000\u2009Hz) in fresh cadaveric human specimens. Results from ear-canal sound stimulation responses show that below 200\u2009Hz, the middle ear impedance is dominated by its stiffness term, limiting sound transmission to the inner ear. During air-conduction, normal ears have approximately equal volume velocities at the oval (stapes) and round windows, known as a two-window system. However, perturbing the impedance of the inner ear with a superior canal dehiscence (SCD), a pathological opening of the bone surrounding the semicircular canal, breaks down this simple two-window system. SCD changes the volume velocity flow in the inner ear, particularly at low frequencies. The experimental findings and model predictions in this study demonstrate that low-frequency auditory and vestibular sound transmission can be affected by a change in the inner-ear impedance due to a SCD.<\/jats:p>","DOI":"10.1121\/1.5046523","type":"journal-article","created":{"date-parts":[[2018,7,24]],"date-time":"2018-07-24T19:56:49Z","timestamp":1532462209000},"page":"332-342","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":11,"title":["Infrasound transmission in the human ear: Implications for acoustic and vestibular responses of the normal and dehiscent inner ear"],"prefix":"10.1121","volume":"144","author":[{"given":"Stefan","family":"Raufer","sequence":"first","affiliation":[{"name":"Program in Speech and Hearing Bioscience and Technology, Harvard Medical School 1 , Tosteson Medical Education Center 35, 260 Longwood Avenue, Boston, Massachusetts 02115, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salwa F.","family":"Masud","sequence":"additional","affiliation":[{"name":"Program in Speech and Hearing Bioscience and Technology, Harvard Medical School 1 , Tosteson Medical Education Center 35, 260 Longwood Avenue, Boston, Massachusetts 02115, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideko H.","family":"Nakajima","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Harvard Medical School 2 , Boston, Massachusetts 02115, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2018,7,24]]},"reference":[{"key":"2023072821172458000_c1","doi-asserted-by":"publisher","first-page":"163","DOI":"10.1016\/j.scitotenv.2016.03.065","article-title":"Health effects from low-frequency noise and infrasound in the general population: Is it time to listen?
