The occupational use of PLDs that produce high-intensity sounds amplifies the danger of cochlear deterioration and high-frequency NIHL especially when used in noisy environments. This study aims to evaluate the incidence and trends of NIHL among medical students using PLDs. Background\/Objectives: The purpose of this study is to assess the prevalence of high-frequency NIHL among PLD-using medical students. Methods: A semi-structured questionnaire covering details on PLD usage, exposure to noisy environments, and hearing difficulties was used to gather the data required. Conventional pure-tone audiometry with extended high-frequency audiometry was preceded by routine clinical evaluation using tuning fork tests and otoscopic examination for hearing loss assessment and to rule out middle-ear pathology. Hearing impairment was determined and categorized according to the Goodman and Clark classification system (250 Hz to 8000 kHz). SPSS version 21 was used in the analysis of the frequency data collected. Results: Out of 100 participants, using conventional PTA, 33% were found to have hearing loss, with 42.9% of males and 23.5% of females affected. Bilateral hearing loss was seen in 36.4% of the cases. Left-sided hearing loss was found to be more common (28%). The duration of usage of PLD had a significant correlation with hearing loss with a p-value &lt; 0.0001. Hearing thresholds were significantly elevated at 16 kHz and 18 kHz in both the right and left ear. Conclusions: The high prevalence of PLD misuse among medical students is a major risk factor for NIHL. To help combat chronic hearing loss, students need to be educated about safe listening levels that can prevent further damage to the cochlea and auditory system.<\/jats:p>","DOI":"10.3390\/jcm14010049","type":"journal-article","created":{"date-parts":[[2024,12,26]],"date-time":"2024-12-26T03:10:49Z","timestamp":1735182649000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Prevalence of High Frequency Noise-Induced Hearing Loss Among Medical Students Using Personalized Listening Devices"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5575-1544","authenticated-orcid":false,"given":"Aishwarya","family":"Gajendran","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Pinderfields Hospital, Wakefield WF1 4DG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6648-9693","authenticated-orcid":false,"given":"Gayathri","family":"Devi Rajendiran","sequence":"additional","affiliation":[{"name":"Department of ENT, ACS Medical College and Hospital, Chennai 600077, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aishwarya","family":"Prateep","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Government Omandurar Medical College, Chennai 600002, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-7629-6844","authenticated-orcid":false,"given":"Harshith","family":"Satindra","sequence":"additional","affiliation":[{"name":"SRM Medical College, Chennai 603203, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rashmika","family":"Rajendran","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Bhaarath Medical College, Chennai 600073, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,26]]},"reference":[{"key":"ref_1","unstructured":"National Institute on Deafness and Other Communication Disorders (2024, October 21).
