Poor hearing thresholds were observed at 16 kHz (n = 19; 54.3%), 18 kHz (n = 24; 68.6%) and 20 kHz (n = 30; 85.7%) in the right ear and at 16 kHz (n = 20; 57.1%), 18 kHz (n = 24; 68.6%) and 20 kHz (n = 30; 85.7%) in the left ear. Absent DPOAEs were observed at 6 kHz (n = 20; 51.7%) and 8 kHz (n = 24; 68.6%) in the right ear and at 6 kHz (n = 17; 48.6%) and 8 kHz (n = 29; 82.9%) in the left ear, possibly indicating that type 2 diabetes specifically targets higher frequency hearing. The ABR results revealed a delayed absolute latency of wave III bilaterally (right ear \u201369%; left ear \u2013 51%), suggesting an impact of this metabolic disease on retro-cochlear pathways.\n\nConclusion: Hearing loss should be recognised as a comorbidity accompanying type 2 diabetes, which indicates the need for routine comprehensive audiological assessments to facilitate early detection and intervention.\n\nContribution: The present findings have implications for audiology clinical protocols; diabetes related health policies and patient education.<\/jats:p>","DOI":"10.4102\/sajcd.v71i1.1035","type":"journal-article","created":{"date-parts":[[2024,8,1]],"date-time":"2024-08-01T07:36:08Z","timestamp":1722497768000},"update-policy":"https:\/\/doi.org\/10.4102\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Audiological profile of patients with type 2 diabetes mellitus"],"prefix":"10.4102","volume":"71","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0637-1377","authenticated-orcid":false,"given":"Sakhile T.","family":"Nkosi","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04qzfn040","id-type":"ROR","asserted-by":"publisher"}],"name":"University of KwaZulu-Natal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4698-6640","authenticated-orcid":false,"given":"Vuyelwa Z.","family":"Peter","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04qzfn040","id-type":"ROR","asserted-by":"publisher"}],"name":"University of KwaZulu-Natal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5282-6144","authenticated-orcid":false,"given":"Jessica","family":"Paken","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04qzfn040","id-type":"ROR","asserted-by":"publisher"}],"name":"University of KwaZulu-Natal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2580","published-online":{"date-parts":[[2024,7,31]]},"reference":[{"key":"ref0","doi-asserted-by":"crossref","unstructured":"Adebola, S.O., Olamoyegun, M.A., Sogebi, O.A., Iwuala, S.O., Babarinde, J.A., & Oyelakin, A.O.
