A Study of Hearing Acuity and the Health of the External Auditory Canal Among Earphone Users in Central India.

Abstract

Background and objective The pervasive use of earphones has raised concerns about its potential impact on hearing acuity and the health of the external auditory canal (EAC). This study aimed to investigate these effects in a sample of individuals in Central India to better understand the associated risks. Materials and methods This observational cross-sectional study was conducted in the Department of Otorhinolaryngology, Acharya Vinoba Bhave Rural Hospital, SawangiWardha. A total of 130 participants aged 15-35 years were divided into two groups: 65 earphone users and 65 non-earphone users. The data collection involved medical histories, clinical examinations, and audiometric testing, including pure-tone audiometry (PTA), impedance audiometry, and otoacoustic emissions (OAE). Participants completed a questionnaire on earphone usage, and EAC health was assessed via physical examinations and photographic documentation. Statistical analyses included descriptive and inferential statistics, with significance set at p<0.05. Results Among earphone users, 45 (69.23%) exhibited hearing loss compared to 11 (16.92%) in non-users (p<0.00001). Noise-canceling earphones were associated with fewer cases of hearing loss (6/45, 13.33%) than non-noise-canceling types (39/45, 86.67%) (p<0.00001). EAC issues were more prevalent in earphone users, with 39 (60%) showing normal conditions versus 52 (80%) in non-users. Impactions of wax, otomycosis, and otitis externa were observed more frequently among earphone users. Conclusions The study highlights a significant association between earphone use and increased risk of hearing loss and EAC issues. Noise-canceling earphones may offer some protective benefits. These findings underscore the need for raising awareness and implementing preventive measures to mitigate potential risks associated with prolonged earphone use.
