A question relevant for cochlear implant users with single-sided deafness (SSD-CI) is whether binaural unmasking can still be achieved if the additional masking is spectrally degraded and shifted. CIs restore some aspects of binaural hearing to these listeners, although binaural unmasking remains limited. Notably, these listeners may experience a mismatch between the frequency information perceived through the CI and that perceived by their normal hearing ear. Employing acoustic simulations of SSD-CI with normal hearing listeners, the present study confirms a previous simulation study that binaural unmasking is severely limited when interaural frequency mismatch between the input frequency range and simulated place of stimulation exceeds 1\u20132\u2009mm. The present study also shows that binaural unmasking is largely retained when the input frequency range is adjusted to match simulated place of stimulation, even at the expense of removing low-frequency information. This result bears implications for the mechanisms driving the type of binaural unmasking of the present study and for mapping the frequency range of the CI speech processor in SSD-CI users.<\/jats:p>","DOI":"10.1121\/10.0006446","type":"journal-article","created":{"date-parts":[[2021,10,1]],"date-time":"2021-10-01T11:57:33Z","timestamp":1633089453000},"page":"2316-2326","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["Reducing interaural tonotopic mismatch preserves binaural unmasking in cochlear implant simulations of single-sided deafness"],"prefix":"10.1121","volume":"150","author":[{"given":"Elad","family":"Sagi","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head & Neck Surgery, New York University Grossman School of Medicine , 550 First Avenue, New York, New York 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahan","family":"Azadpour","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head & Neck Surgery, New York University Grossman School of Medicine , 550 First Avenue, New York, New York 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan","family":"Neukam","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head & Neck Surgery, New York University Grossman School of Medicine , 550 First Avenue, New York, New York 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole Hope","family":"Capach","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head & Neck Surgery, New York University Grossman School of Medicine , 550 First Avenue, New York, New York 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario A.","family":"Svirsky","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head & Neck Surgery, New York University Grossman School of Medicine , 550 First Avenue, New York, New York 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2021,10,1]]},"reference":[{"key":"2023080508253410000_c1","doi-asserted-by":"publisher","first-page":"39","DOI":"10.1097\/MAO.0b013e3181fcf271","article-title":"Comparison of pseudobinaural hearing to real binaural hearing rehabilitation after cochlear implantation in patients with unilateral deafness and tinnitus","volume":"32","year":"2011","journal-title":"Otol.
