Methods: Eleven bimodal users (Na\u00ecda CI Q70 + contralateral hearing aid) were enrolled in our study. The users\u2019 own hearing aids were replaced with the Phonak Na\u00ecda Link Ultra Power and fitted following the new formula. Speech intelligibility was assessed in quiet and noisy conditions, and comparisons were made with the results obtained with the users\u2019 previous hearing aids and with the Na\u00edda Link hearing aids fitted with the NAL-NL1 generic prescription formula. Results: Using Phonak Na\u00ecda Link Ultra Power hearing aids with the Adaptive Phonak Digital Bimodal fitting formula, performance was significantly better than that with the users\u2019 own rehabilitation systems, especially in challenging hearing situations for all analyzed subjects. Conclusions: Speech intelligibility tests in quiet settings did not reveal a significant difference in performance between the new fitting formula and NAL-NL1 fittings (using the Na\u00edda Link hearing aids), whereas the performance difference between the two fittings was very significant in noisy test conditions.<\/jats:p>","DOI":"10.3390\/audiolres11020018","type":"journal-article","created":{"date-parts":[[2021,5,12]],"date-time":"2021-05-12T10:59:12Z","timestamp":1620817152000},"page":"200-206","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Integrated Bimodal Fitting for Unilateral CI Users with Residual Contralateral Hearing"],"prefix":"10.3390","volume":"11","author":[{"given":"Gennaro","family":"Auletta","sequence":"first","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4392-9739","authenticated-orcid":false,"given":"Annamaria","family":"Franz\u00e8","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Laria","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmine","family":"Piccolo","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmine","family":"Papa","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pasquale","family":"Riccardi","sequence":"additional","affiliation":[{"name":"Advanced Bionics GmbH Max-Eyth Strasse 20, 70736 Fellbach-Oeffingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7486-0140","authenticated-orcid":false,"given":"Davide","family":"Pisani","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Experimental and Clinical Medicine, Magna Graecia University, Viale Europa, 88100 Catanzaro, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelo","family":"Sarnelli","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0614-7583","authenticated-orcid":false,"given":"Valeria","family":"Del Vecchio","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2728-339X","authenticated-orcid":false,"given":"Rita","family":"Malesci","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5055-9150","authenticated-orcid":false,"given":"Elio","family":"Marciano","sequence":"additional","affiliation":[{"name":"Unit of Audiology, Department of Neuroscience, Reproductive Sciences and Dentistry, University of Naples \u201cFederico II\u201d, via Pansini 5, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1097\/01.HJ.0000399149.53245.b1","article-title":"Who is a cochlear implant candidate?","volume":"64","author":"Gifford","year":"2011","journal-title":"Hear.
