Prevalence of Occupational Noise Induced Hearing Loss among Textile Industry Workers of Bangladesh

Abstract

Background: Occupational noise exposure remains a major public health concern, particularly in the textile industry, where workers are continuously exposed to high-intensity noise. Noise-induced hearing loss (NIHL) is one of the most prevalent occupational health hazards, often leading to irreversible hearing impairment and reduced quality of life.

Objective: This study aims to determine the prevalence of NIHL among textile industry workers in Bangladesh and identify associated risk factors to inform workplace safety strategies.

Methodology: This cross-sectional study was conducted in the Department of Otolaryngology, Monno Medical College and Hospital, Manikganj from March 2023 To February 2024 among 185 textile worker’s exposed to occupational noise levels exceeding 85 dB. Participants underwent pure-tone audiometry to assess hearing impairment. Data were collected through structured questionnaires and analyzed using SPSS version 26.

Results: NIHL prevalence was 58.38%, with a significant association with age (p < 0.001). Workers aged 38–47 years had the highest prevalence (80.95%). Bilateral hearing loss was most common (69.44%), with 4000 Hz being the most affected frequency. The highest risk was observed among loom shade workers (95–100 dB).

Conclusion: The high prevalence of NIHL underscores the need for stricter noise control measures, mandatory hearing protection, and regular audiometric screening in the textile industry. Strengthening occupational health policies is crucial to safeguarding worker well-being.
