The aim of our research was to study the differential effect of type 1 diabetes mellitus (T1DM) on two different age groups. Audiological investigation was carried out in 42 patients and 25 controls at the same age groups. Investigation of the conductive and sensorineural part of the hearing system by pure tone audiometry, distortion product otoacoustic emission measurement and acoustically evoked brainstem response registration were evaluated. Among the 19-39-year-old people the incidence of hearing impairment was not different in the diabetes and control groups. Among the 40-60-year-old people hearing impairment was more common in the diabetes group (75%) than in the control group (15,4%). Among patients with type 1 diabetes, the mean threshold values were higher in both age groups at all frequencies although significant difference was in 19\u201339 years old group: 500-4000Hz right ear, 4000Hz left ear, in 40\u201360 years old group: 4000\u20138000 Hz both ears. In the 19\u201339 years old diabetes group only at 8000 Hertz on the left side was a significant (p&lt;0,05) difference in otoacoustic emissions. In the 40\u201360 years old diabetes group significantly less otoacoustic emissions at 8000 Hz on the right side (p&lt;0,01) and at 4000-6000-8000 Hertz on the left side, (p&lt;0,05, p&lt;0,01, p&lt;0,05 respectively) was present compared to the control group. According to ABR (auditory brainstem response) latencies and wave morphologies, a possible retrocochlear lesion arose in 15% of the 19\u201339 years old and 25% of the 40\u201360 years old diabetes group. According to our results, T1DM affects negatively the cochlear function and the neural part of the hearing system. The alterations are more and more detectable with aging.<\/jats:p>","DOI":"10.1371\/journal.pone.0285740","type":"journal-article","created":{"date-parts":[[2023,5,19]],"date-time":"2023-05-19T17:28:10Z","timestamp":1684517290000},"page":"e0285740","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":8,"title":["Changes in the cochlear and retrocochlear parts of the auditory system in 19\u201339 and 40\u201360 years old patients with type 1 diabetes mellitus"],"prefix":"10.1371","volume":"18","author":[{"given":"Mih\u00e1ly","family":"Horv\u00e1th","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5990-4889","authenticated-orcid":true,"given":"Zolt\u00e1n","family":"Herold","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianna","family":"K\u00fcstel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L\u00e1szl\u00f3","family":"Tam\u00e1s","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P\u00e9ter","family":"Prekopp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anik\u00f3","family":"Somogyi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3036-7957","authenticated-orcid":true,"given":"Anita","family":"G\u00e1borj\u00e1n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,5,19]]},"reference":[{"key":"pone.0285740.ref001","doi-asserted-by":"crossref","first-page":"242","DOI":"10.2471\/BLT.21.285643","article-title":"The world report on hearing, 2021","volume":"99","author":"S Chadha","year":"2021","journal-title":"Bull World Health Organ"},{"key":"pone.0285740.ref002","first-page":"493","article-title":"Uses and abuses of hearing loss classification.","volume":"23","author":"JG Clark","year":"1981","journal-title":"ASHA"},{"key":"pone.0285740.ref003","doi-asserted-by":"crossref","first-page":"1268","DOI":"10.1111\/dme.13086","article-title":"Functional hearing deficits in children with Type 1 diabetes","volume":"33","author":"G Rance","year":"2016","journal-title":"Diabet Med J Br Diabet Assoc"},{"key":"pone.0285740.ref004","doi-asserted-by":"crossref","first-page":"1111","DOI":"10.1016\/S0140-6736(05)67423-5","article-title":"1.
