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 Atelier 7hz. 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.

Technical mastery of accounting, payroll and practical analysis within the reach of the company to ensure better service. Strong experience in the field with a good sense of adaptability and openness.

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 Atelier 7hz 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 Atelier 7hz 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.
