Regulations
In Quebec, the responsibility for compliance with noise limits lies with the municipalities. However, if the municipality does not have a specific regulation on noise, it is the “Note on the Traitement des plaintes sur le bruit et exigences aux entreprises qui le génèrent” applies (Legal reference LRQ (c. Q -2), articles 20 and 22).
There are two exceptions: quarries and sand pits. In this case, it is the “Regulation on sand pits, chapter Q-2, r.7.1” which applies.
When applying for an operating permit from the “Ministère de l’Environnement et de la Lutte aux Changements Climatiques” (MELCC), companies must agree to comply with specific noise criteria depending on the zoning. If the company is unable to meet these noise levels, it must submit an action plan and timetable to the MELCC to remedy the problem.
Solutions
Mecanum’s acoustics and vibration experts have all the tools and knowledge to help you implement the necessary solutions at the best cost:
Environmental Noise Evaluation Following MELCC Specifications
Mecanum has the expertise and the means to carry out your evaluation measures according to MELCC standards for:
- Acoustic evaluation every 3 years as part of the regulation on quarries and sand pits,
- Application for authorization to operate a business.
Noise Source Determination & Characterization
Mecanum experts have developed a reliable and efficient acoustic imaging tool to detect noise sources: the LF-ANT acoustic camera. This tool, combined with acoustic power measurements, makes it possible to determine and quantify the various sources of noise.
Environmental Noise Simulations
Environmental noise simulations allow you to develop acoustic models of the sound environment around your facilities.
The input data for the simulations are the acoustic power measurements of the various noise sources carried out by Mecanum experts. Once assembled, the model is validated by comparing measured and calculated sound pressure levels at different measurement points.
Once the model has been validated, it can be used to predict the effect of modifications or the implementation of different solutions. Mecanum experts can easily assess the solutions with the best cost-effectiveness ratio.
