Determinants of Noise-Induced Hearing Loss among Drivers in Bisha, Saudi Arabia

Introduction: Noise exposure is a preventable cause of hearing loss, with traffic being a primary source of loud sounds that can lead to noise-induced hearing loss. Research indicates that hearing loss is notably prevalent among drivers. Objective: This study aimed to estimate the prevalence of noise-induced hearing loss and its associated factors among drivers in Bisha City, Saudi Arabia. Materials and Methods: A cross-sectional study was conducted in Bisha City, Saudi Arabia, involving adult car drivers aged 18 years and older. The study used an online link with a validated questionnaire to measure noise-induced hearing loss among drivers. The questionnaire was distributed via social media using the author’s professional networks, friends, and family, allowing any viewer in Bisha City to respond voluntarily from November 2024 to January 1, 2025. Results: Of the 387 participants, 213 (55%) were male and 174 (45%) were female, with a mean age of 29.6 years. A total of 30 drivers (7.7%) were found to have NIHL. The noise level inside the car was statistically significant (P = 0.001) in relation to hearing loss. Conclusion: Noise-induced hearing loss was observed among car drivers, regardless of the car’s production year or driving duration. Drivers exposed to noise in their cars could potentially impair their hearing. We recommend implementing measures such as improving road quality, adding noise cancellation features to cars, and screening drivers’ hearing abilities to ensure their safety.
