Acoustics and Vibrations

In the industrial workplace, noise has long been recognized as a potential threat to workers' hearing. With noise sources constantly increasing in today's environment, noise can become harmful to the well-being of the public at large. Impacts on human mental and physical health can often be attributed to noise pollution and, as a result, noise control is a critical challenge.

SNC-Lavalin Environment has been active in the noise control and vibration field for more than 20 years, participating in studies evaluating health in the workplace, noise transmission in residential buildings, and the impact of environmental noise on populations. Our company has the expertise and the necessary tools to identify disruptive noise sources and propose practical and economically viable solutions that meet your expectations. Our professional acoustic team is supported by SNC-Lavalin's vast range of multidisciplinary expertise covering all aspects of a project.
