Bhiwandi, Maharashtra, stands as a critical industrial hub for India’s textile sector, where the continuous operation of high-speed powerloom machinery creates a persistent acoustic challenge. This study investigates the extent of noise pollution within the Naigaon cluster, assessing how industrial operations can impact both workers and the surrounding community. Using a calibrated Sound Level Meter, monitoring was conducted across industrial sheds, transit streets, and residential zones to evaluate adherence to safety standards. The findings reveal that noise levels within the manufacturing units consistently exceed the permissible exposure limits. Furthermore, ambient noise in nearby residential areas is found to be significantly higher than the national standards established for daytime comfort. Statistical analysis, including independent samples t-tests, confirmed a substantial reduction in noise during weekly closures, identifying the powerloom machinery as the primary source of environmental pollution. Additional analysis through One-Way ANOVA and Pearson correlation demonstrated a clear spatial gradient, showing a direct and near-perfect link between industrial intensity and its acoustic impact on the community. The study concludes that current noise levels pose a potential risk to long-term auditory health. To prevent long-term hearing loss, the study recommends implementing acoustic barriers and mandatory personal protective equipment (PPE).
