Integrated Noise Management Strategies in Industrial Environments: A Framework for Occupational Safety, Health, and Productivity

Noise exposure in rubber manufacturing poses significant risks to worker health, safety, and productivity. This study explores these challenges via an integrated approach that combines task-based and group noise measurements as required by Directive 2003/10/EC, noise mapping, real-time monitoring, and worker feedback. Noise levels were found to range from 81 to 89 dB(A) across worker groups, with task-specific peaks exceeding 91 dB(A) near high-noise machinery. To mitigate these risks, engineering controls, including acoustic barriers and machine isolation, were proposed alongside administrative measures such as task rotation and improved access to personal protective equipment. The analysis demonstrated a link between noise levels and reduced productivity, emphasizing the need for targeted interventions. Integrating IoT sensors and AI for real-time noise monitoring offers opportunities to increase compliance, reduce exposure, and improve safety outcomes. Whilst engineering controls involve higher initial investments, cost-benefit analysis highlights their long-term advantages in reducing health-related expenses and improving productivity. This study reinforces the importance of a proactive, worker-centered approach to noise management in rubber manufacturing, emphasizing sustainability, risk mitigation, and the adoption of innovative technologies to create safer and more efficient workplaces.
