Over the past years, Mr. Raphaël Duée has acquired a multidisciplinary experience in the architectural, environmental, transportation and industrial acoustic and vibration fields. After being team leader for the engineering firm WSP (Décibel Consultants) and deputy manager of the engineering team of RATP, Mr. Duée now leads his own company A7hz. He has worked on a large set of projects such as acoustic optimization of residential and commercial projects, acoustic and vibration impact studies of railway lines, as well as the optimization of room acoustics, P.A. systems, interior insulation, HVAC systems, monitoring stations, etc. Mr. Duée took part in several research projects in the environmental acoustic and room acoustic domains.

Mr. Jean-Frédéric Desjardins, a building mechanics engineer acquired, at the start of his career, a very good experience in building mechanics. By, he completed a training in noise and vibration control at master’s level in 2017 in order to perfect his already acquired knowledge. He then very quickly specialized in acoustics and soundproofing, which also allowed him to acquire good experience in this field. It is therefore able to assist all professionals both at the architectural and mechanical level. He is already working on several large-scale residential tower-to-condo projects in the Montreal region, commercial projects (office towers), institutional projects (school, seniors’ center, hospitals, courthouses, etc.)
He therefore offers clients expertise and added value to the projects assigned to him since he is able to quickly understand all the issues of the various disciplines involved in a project.

Valérie is a graduate of the École de technologie supérieure. She completed a bachelor’s degree in mechanical engineering. She also worked there as a research and development intern. Previously, she obtained her college diploma in aircraft maintenance technology. Having worked in this noisy environment, she developed a sensitivity on the subject of hearing loss. In addition, it seeks to improve the existing in order to reduce the environmental impacts of society while promoting comfort and utility. As a result, she joined the A7hz team as a research manager in a desire to participate in the reduction of noise pollution as well as to collaborate on innovation and democratization projects in the field of acoustics.

Mr. Sami Chabane graduated in acoustics and sound design from the University of Aix-Marseille. Following an internship in an acoustic design office in Paris, he developed an interest in the acoustics of rooms and buildings. Sami joined the A7hz team as a study manager in acoustics and vibration.

Mr. Alexis Martin graduated from ETS (Maîtrise en Génie Électrique at CRITIAS) and École Centrale d’Électronique (Baccalauréat en Génie Électrique, Paris) in 2015. He has also trained in Non-Violent Communication and is a certified coach. Passionate about music, audio and electronics, he is responsible for the development of acoustic and vibration monitoring stations and an internal coach. His interests are diverse, and include audio, electronics, acoustics, signal processing, biomedical and occupational health and safety. He also organizes internal coaching sessions at A7hz.
