Construction sites have grown considerably quieter in recent years. It isn’t your imagination: thanks to a boom in modular construction, more and more work that has traditionally been done on-site has moved indoors.
However, while this trend increases worker productivity, its effect on worker health and safety remains unknown, specifically when it comes to noise.
In a new paper published in the Journal of Cleaner Production, researchers at Concordia propose a new framework to predict noise levels in modular construction factories and workplaces using probability-based modelling and acoustic condition simulations. They believe their work can help calculate workers’ exposure to noise, and so lead to improved health and safety conditions.
“Many companies just focus on improved productivity when they move their tools and machines indoors,” says Sang Hyeok Han, an assistant professor in the Department of Building, Civil, and Environmental Engineering at the Gina Cody School of Engineering and Computer Science. “But in this study, we are showing companies that they should also consider mitigating noise exposure to their workers.”
Han is also a member of Concordia’s new Centre for Innovation in Construction and Infrastructure Engineering and Management (CICIEM).He co-authored the paper with Joonhee Lee, an assistant professor in his same department. Their PhD student Sanam Dabirian is the paper’s lead author.
