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. Maxime Léger has acquired, over the past five years, very good experience in the engineering profession and in project management. After being a mechanical engineer and project manager at GCM Consultants and Via Rail Canada, he now works at A7hz as a project manager in acoustics and vibrations. His technical and organizational skills are major assets for the company.

Kristofer Tassis received his civil engineering undergraduate degree from the University of Toronto, specializing in transportation and environmental engineering. While there, he took advantage of the co-operative program working as a process engineer, implementing process improvements and managing others. He is a member of the Professional Engineers of Ontario (PEO).

He was initially exposed to acoustic engineering while working within the drywall industry as an estimator/project manager and decided to further pursue a career in acoustical engineering. Kristofer has worked as an acoustic engineer in the Toronto area for over 4 years and has extensive experience preparing noise and vibration reports, acoustic field measurements, noise modelling, and with guideline/code requirements. Kristofer is now part of the Atelier 7hz team as the Toronto director with the goal to develop the business/team and carry out acoustic studies in the Toronto area.

Frédéric Gauthier studied accounting at ESG-UQAM. He joined the team because of his interest in the field of acoustics. Simultaneously, he is studying informatics and software development.

Trained in physics and electroacoustic music at Concordia University in Montreal, Jan Pienkowski’s work experience spans over 20 years as a physicist, programmer, music composer, stage artist, sound engineer and teacher. His physics and programming projects led him to work for the ETS acoustic and vibration research laboratories (CRITIAS and ICAR), IREQ research laboratories at Hydro-Québec, Averna technologies and physics laboratories. McGill University, while his musical projects include works for the COP21 Summit of the United Nations in Paris, the British Council, the Society for Arts and Technology, the Montreal Opera and Place des arts. Jan brings his passion for everything related to audio, acoustics and technology to A7hz to continue developing projects in these areas.

Mr. Denis Bissengué has an engineering background in mechanical engineering, specializing in numerical analysis and simulation of vibratory phenomena and modeling of mechanical waves by the finite element method. He joined the A7hz team as an acoustics and vibration researcher, he is also the manager of our vibration stations.

His various experiences in the field of mechanical engineering and his rigor are major assets for the company.

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.

M. Jacques Zdun is a graduate from ÉTS in mechanical engineering with a focus in aerospace engineering. After an internship in the mining industry in Abitibi, he developed an interest for acoustics and vibrations measuring equipment.
Jacques then joined our team as an acoustics and vibrations engineer.

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.
