SILENT HAZARDS: NAVIGATING THE INVISIBLE RISKS OF NOISE AND VIBRATION IN INDUSTRIAL WORKSPACES

Background:Occupational noise and vibration exposure in industrial workplaces remain significant hazards, contributing to adverse health effects, including hearing impairment, musculoskeletal disorders, cardiovascular problems, and psychological disturbances. While previous studies have documented these risks, comprehensive knowledge regarding effective hazard mitigation remains insufficiently integrated across industrial sectors.

Objectives:This review aims to comprehensively synthesize recent literature (2014-2024) on the health impacts, industry-specific hazards, effectiveness of engineering controls, regulatory policies, and behavioural factors influencing worker compliance with noise and vibration mitigation measures. Additionally, it aims to identify gaps in existing research and suggest future research directions.

Methods:A systematic literature review of 25 scientific and medical research papers published from 2014 to 2024 was conducted, sourcing data from PubMed, ScienceDirect, IEEE Xplore, and other relevant scientific repositories. Studies were selected based on methodological rigor, industrial relevance, and the significance of findings, encompassing various sectors, including construction, manufacturing, mining, and transportation.

Results:Reviewed studies consistently demonstrate significant health impacts related to occupational noise and vibration exposure. Industry-specific differences were identified, with construction and mining showing particularly high exposure risks. Engineering controls, including acoustic enclosures, active vibration-reduction seating, and redesigned equipment, effectively reduced noise and vibration exposures. Worker training and organizational safety culture significantly influenced compliance and the effectiveness of implemented interventions. Case studies highlighted successful implementations, demonstrating tangible improvements in worker health outcomes and regulatory compliance.

Conclusion:Robust mitigation strategies incorporating engineering solutions, regulatory frameworks, targeted training, and cultural interventions significantly reduce occupational noise and vibration risks. Future research should explore combined exposure effects, refine existing risk prediction models, evaluate emerging technologies, and enhance interventions in small-to-medium enterprises to strengthen occupational health outcomes.
