摘要

Background

This research explores the prevalence of occupational noise-induced hearing loss (NIHL) among ENT clinic patients and the related factors. We aim to assess the prevalence of NIHL, examine noise-exposed workers' characteristics, and identify factors causing high-frequency hearing loss (HFHL).

Methods

One hundred sixty workers were divided into two groups based on noise exposure duration: less than 5 years and over 5 years. We compared hearing thresholds, demographics, hearing aid usage, and preventive measures between these groups. Audiometric evaluations gauged hearing levels at various frequencies. Demographic data, including age, gender, education, and smoking habits, were collected.

Results

Most participants were male (84.4%) and under 40 (63.1%). 44.4% had worked over 5 years, 29.4% used hearing aids, and 51.9% had tinnitus. Audiometry showed increased hearing thresholds at higher frequencies, especially 4 kHz, 6 kHz, and 8 kHz. Regression showed tinnitus and longer job durations as significant predictors of NIHL.

Conclusion

The study reveals the vulnerability of noise-exposed workers to HFHL. Tinnitus is a primary predictor, and long job durations also affect hearing. The findings underscore the importance of hearing conservation, especially for workers with tinnitus and prolonged noise exposure.
