Mission, Vision and Values

MJM Mission

MJM Acoustical Consultants Inc. provides our customers (developpers, contractors, architects, building owners, etc) in Québec and worldwide  clear recommendations which can be easily put into place using commonly available materials often distributed by a large number of suppliers.

MJM dedicates 100% of its resources to acoustical consulting and noise control and is totally independent of any supplier or manufacturer of acoustical materials and vibration isolators. This ensures our clients that they benefit from the highest quality consultation and that their interests are not in conflict with our own.

Our recommendations are based on the technical knowledge acquired during our 33 years of existence, through measurements in laboratory or in situ and through many research projects and scientific studies carried out on behalf of the Canada Mortgage and Housing Corporation (CMHC).

MJM Vision

• Impose the acoustical consultant as a key member of the professional team (structural, mechanical engineer, architect, etc.) in all the construction, renovation and building development projects.
• Aknowledge the role and competences of the acoustical consultant and promote the application of the best practices in architectural acoustics and noise and vibration control.

MJM Values

• Provide rigorous and easily understandable measurements reports, evaluations and recommendations.
• Provide a fast, rapidly available and cost effective customer service.
• Work as a team and develop our employees technical and social skills as well as their knowledge.
• Innovate in the acoustical instrumentation and procedure and the acoustical simulation software and share with the community to ensure the diffusion in the best practices.
