What sets us apart

MJM provides clear recommendations which can be easily put into place using commonly available materials often distributed by a large number of suppliers. 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) in the laboratories of the National Research Council of Canada (NRC) and in the Domtar Acoustical Laboratory leased and operated by MJM on an exclusive basis from 1992 to 2008. MJM research reports have been distributed all over the world, more specifically in United States, Japan, Europe, and Australia: they are available to the public on our web site and can be downloaded free of charge.

Sharing with the public and the scientific community the knowledge acquired by MJM through research projects dedicated to acoustics and noise control is what sets us apart from the other acoustical consulting firms. Amongst other things, it led to the creation of the new ASTM E 2964-14 standard for the measurement of the sound isolation provided by doors: the measurement method outlined in the standard was developed by MJM in 1991 in the course of a research project subsidized by the CMHC. It is also a testimony to our rigor, objectivity, and integrity as well as a commitment to provide uncompromised professional services to our clients.

Integrity and Independence

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.
