Summary
Electro production workers face a high risk of noise-induced hearing loss (NIHL). Occupational noise exposure, aging, and smoking are significant predictors of this hearing impairment.
Area of Science:
- Occupational Health
- Audiology
- Environmental Health
Background:
- Electro production environments often involve high noise levels.
- Hearing loss is a significant occupational health concern in industrial settings.
- Understanding the prevalence and risk factors for hearing loss is crucial for worker protection.
Purpose of the Study:
- To determine the prevalence of hearing loss among electro production workers.
- To identify the key determinants of hearing loss in this occupational group.
- To compare hearing loss rates between electro production workers and office workers.
Main Methods:
- Audiometric testing was conducted on 93 electro production workers and 51 office workers.
- A self-administered questionnaire collected data on demographics, medical history, ototoxic drug use, hobbies, and smoking habits.
- Workplace noise levels were measured, and statistical analyses, including multivariate analysis, were performed.
Main Results:
- Electro production workers were exposed to high noise levels.
- 44% of electro production workers exhibited sensorineural hearing loss, primarily at 4000 Hz.
- Occupational noise exposure (OR: 7.51), aging (OR: 5.34), and smoking (OR: 2.47) were significant predictors of noise-induced hearing loss (NIHL).
Conclusions:
- Electro production workers have a high incidence of NIHL, predominantly affecting the 4000 Hz frequency.
- Occupational noise exposure is the primary risk factor for NIHL in this population.
- Interventions are necessary to mitigate the risk of NIHL among electro production workers.
