A Critical Evaluation into the Effectiveness of Occupational Noise Protection in a South Wales Piling Company

Piling operations involving impact machinery and vibratory rigs generate sustained noise exceeding safe thresholds, contributing to auditory and broader health impacts, including stress and cognitive decline. Occupational noise induced hearing loss poses significant risk to worker health yet remains under-addressed compared to other hazards. This study critically evaluates the effectiveness of occupational noise protection strategies on piling operations within the construction sector in South Wales, UK. Using mixed methods, the research engaged with piling contractors, incorporating data from 100 questionnaires and 15 interviews. Fifteen participants recorded noise readings using personal noise dose meters over a 5-day period, providing detailed insights into daily workplace noise exposure. The study assesses compliance with UK legislation, including the Control of Noise at Work Regulations (2005) and examines the adequacy of personal protective equipment (PPE) and noise management practices. Findings reveal variability in compliance and significant gaps in addressing high noise levels inherent to piling activities. The research emphasises the need for improved engineering controls, effective PPE, and robust training programs, alongside stricter enforcement and innovative noise mitigation strategies to safeguard worker health in construction.
