Bilateral cochlear implant (CI) users provide a controlled model to investigate how artificially introduced interaural timing disparities affect binaural hearing. This study investigates whether introducing a unilateral time delay in CI stimulation affects speech perception in noise and spatial release from masking (SRM). Methods: Eleven bilateral CI users were tested using the German Oldenburger Sentence Test (OLSA) under three spatial noise conditions (S&lt;sub&gt;0&lt;\/sub&gt;N&lt;sub&gt;0&lt;\/sub&gt;, S&lt;sub&gt;0&lt;\/sub&gt;N&lt;sub&gt;+90\u00b0&lt;\/sub&gt;, S&lt;sub&gt;0&lt;\/sub&gt;N&lt;sub&gt;\u201390\u00b0&lt;\/sub&gt;), with and without a 10-ms delay introduced to the right CI processor. Speech reception thresholds (SRTs) and SRM were analyzed using repeated-measures ANOVA. Results: No significant differences in SRT or SRM were found between the delay and non-delay conditions across all spatial configurations. A consistent right-ear advantage was observed, but the induced interaural delay did not significantly impair speech-in-noise performance. Conclusion: A unilateral 10-ms delay in CI stimulation does not significantly affect speech perception or SRM in bilateral CI users. These findings indicate that a unilateral 10-ms interaural delay does not measurably affect speech perception or SRM in bilateral CI users. This observation is consistent with previous reports suggesting limited functional use of fine-grained interaural timing cues during speech-in-noise processing, although the present study cannot draw conclusions about smaller interaural delays.<\/jats:p>","DOI":"10.1159\/aud\/abnag007","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T11:20:36Z","timestamp":1790335236000},"page":"1-1","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Interaural Timing Delays on Speech Perception in Noise in Bilateral Cochlear Implant Users"],"prefix":"10.1159","author":[{"given":"Philipp","family":"Zelger","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Raffelsberger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annett","family":"Franke-Trieger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Keintzel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joachim","family":"Schmutzhard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3531-1549","authenticated-orcid":false,"given":"Franz","family":"Muigg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Rungger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josef","family":"Seebacher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,10,15]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1080\/14992020600782626"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.heares.2014.10.004"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.cub.2009.05.035"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1609-05.2005"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1177\/23312165221094202"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1121\/1.4812441"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1121\/1.398697"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1121\/1.428211"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1121\/1.4729575"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1177\/2331216519858311"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.3389\/fnins.2023.1257720"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1121\/1.1936489"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1121\/1.1894635"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1121\/1.1908276"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1121\/1.1911708"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1097\/AUD.0b013e31829d14cb"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1097\/AUD.0000000000000260"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1007\/s10162-018-00697-w"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1177\/2331216516665608"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1097\/AUD.0000000000000708"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1177\/2331216519843876"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.heares.2018.10.015"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1177\/23312165231171987"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0045296"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1044\/2024_AJA-24-00026"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1080\/14992020500057517"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1121\/10.0034869"}],"container-title":["Audiology and Neurotology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/aud\/abnag007","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,20]],"date-time":"2026-10-20T16:01:03Z","timestamp":1792512063000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/aud\/abnag007"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,15]]},"references-count":27,"URL":"https:\/\/doi.org\/10.1159\/aud\/abnag007","archive":["Portico"],"relation":{},"ISSN":["1420-3030","1421-9700"],"issn-type":[{"value":"1420-3030","type":"print"},{"value":"1421-9700","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,15]]}}}
