While CHL is traditionally considered a peripheral auditory disorder, emerging evidence suggests that it may also affect central auditory processing, especially under complex acoustic conditions. Methods: Thirty individuals diagnosed with CHL and thirty age-matched participants with normal hearing were recruited from the Audiology Unit of Gazi University. All participants underwent comprehensive audiological evaluations, including the Turkish Hearing in Noise Test (T-HINT). Speech recognition thresholds (SRTs) were measured adaptively in four listening conditions: quiet and noise presented from the front, right, and left. Speech-spectrum noise was delivered at 65 dB SPL. Results: Participants with CHL demonstrated significantly elevated SRTs across all noise conditions compared to the control group, indicating reduced speech-in-noise intelligibility. However, speech discrimination scores in quiet did not differ significantly between groups. Notably, larger air-bone gaps at low frequencies were strongly correlated with poorer SRTs, suggesting a frequency-specific vulnerability in noisy environments. Conclusion: CHL substantially impairs speech perception in noise, primarily due to the detrimental effects of low-frequency air-bone gaps. These findings underscore the crucial role of low-frequency auditory input in the temporal and spectral processing of speech, underscoring the need for frequency-specific diagnostic and rehabilitative strategies in clinical audiology. &lt;\/p&gt;<\/jats:p>","DOI":"10.1159\/000550374","type":"journal-article","created":{"date-parts":[[2026,1,6]],"date-time":"2026-01-06T17:00:53Z","timestamp":1767718853000},"page":"230-238","source":"Crossref","is-referenced-by-count":0,"title":["Evaluating Speech-in-Noise Deficits in Conductive Hearing Loss: The Underestimated Role of Low-Frequency Air-Bone Gaps"],"prefix":"10.1159","volume":"87","author":[{"given":"Mustafa","family":"Seyrek","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7695-4703","authenticated-orcid":false,"given":"Burak","family":"Kabi\u015f","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suat","family":"\u00d6zbilen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B\u00fclent","family":"G\u00fcnd\u00fcz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,1,6]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1044\/jshd.4502.143"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1121\/1.409834"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2003.08.015"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1002\/cne.902380402"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1007\/s10162-011-0271-6"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1055\/s-0040-1715981"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s10571-020-00829-y"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097\/AUD.0000000000000787"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1044\/2024_AJA-24-00055"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1121\/10.0014418"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2016.01268"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1080\/14992020802056027"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.3109\/00381797109075536"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1590\/1982-0216201423512"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1097\/AUD.0b013e3181731e2e"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.3342\/ceo.2012.5.S1.S73"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.heares.2010.11.003"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1097\/AUD.0000000000000802"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016\/s1808-8694(15)30843-0"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjorl.2016.02.010"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1097\/AUD.0000000000000431"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1121\/1.3021299"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1186\/s12868-022-00721-z"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.5152\/iao.2016.1731"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.3389\/fnins.2021.721922"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.5152\/b-ent.2022.21629"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.0226-16.2016"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0142341"}],"container-title":["ORL"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000550374","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T16:01:01Z","timestamp":1784736061000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000550374"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,6]]},"references-count":28,"journal-issue":{"issue":"5-6","published-online":{"date-parts":[[2026,7,22]]},"published-print":{"date-parts":[[2026,8,5]]}},"URL":"https:\/\/doi.org\/10.1159\/000550374","archive":["Portico"],"relation":{},"ISSN":["0301-1569","1423-0275"],"issn-type":[{"value":"0301-1569","type":"print"},{"value":"1423-0275","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1,6]]}}}
