Awareness About Noise and its Effects Among Industrial Workers in Hyderabad

Purpose: This study investigated awareness and experiences related to occupational noise-induced hearing loss (NIHL) among 60 industrial workers in Hyderabad, drawn equally from large-scale, small-scale, and construction industries.Methodology: Participants, aged 25 to 60 with over five years of work experience, completed a validated questionnaire assessing knowledge of noise, hearing conservation practices, and the auditory and non-auditory effects of noise exposure.Result: Findings revealed that while all workers understood what noise is and 95% were exposed to high noise levels for at least 8 hours daily, less than 50% underwent regular hearing evaluations.Awareness of hearing conservation measures and ear protective devices (EPDs) was moderate, but consistent use remained limited.Only 68.33% used EPDs regularly, despite 80% being aware of them and 73.33% being encouraged to wear them.Auditory effects were commonly reported, with 83.33% experiencing hearing changes after work and only 51.66% reporting recovery after rest.Tinnitus was reported by 10% of workers.Construction workers were the least aware and least protected, while large-and small-scale industry workers showed similar, higher levels of awareness and practice.Non-auditory effects such as sleep disturbance, heart rate and breathing changes, irritation, and reduced performance were rare across all industries. Conclusion:The study emphasizes the need for stronger awareness programs, consistent use of hearing protection, regular screenings, and effective enforcement of noise safety regulations to reduce the impact of NIHL in industrial settings.
