    • I have had the privilege of working with Denis Blanchet on several projects using measurements and computer analyses to model the noise and vibration of vehicles and engines. As the project manager Denis was effective in coordinating the many complicated activities to bring the projects to successful completion. Denis is a leader in applying Statistical Energy Analysis (SEA) to noise and vibration problems. His active participation in conferences on this subject has been a great benefit to the profession.

    • Since 2011 Denis Blanchet cooperated with the German Wind Noise Working Group composed of Audi, Daimler, Porsche and Volkswagen. Denis contributed to the development of a new numerical approach that allows to describe and estimate the interior wind noise using CFD generated surface pressure distribution. He has a broad knowledge in SEA-, BEM- and FEM-Methods such that we had a valuable collaboration with him for related validation experiments.

    • I had the opportunity to work with Denis as he was Engineering Services Manager at ESI-Group. I appreciate his ability to interpret and orient our needs in the right perspective and to adequate solutions. His experience on simulation-solutions in the automotive industry qualify Denis as a valuable partner. I wish him a successful start in the new business.

    • In my work I have to deal with VibroAcoustics modelling for the marine industry. To further develop the team's competences, we outsourced a VibroAcoustics Modelling course to Denis. Denis was an extremely knowledgeable instructor who connected well with his audience, providing practical and appropriate examples from his vast experience. His real world experience in various sectors (marine / automotive) and know-how helped my overall understanding of the theoretical concepts and opened my vision on what more could be achieved using our VA modelling tool. On the personal side, Denis is a very friendly and positive person with whom I would be delighted to work again in the future.

    • Denis is a worldwide reference in vibro-acoustics. He has been in the industry for so long and he has a proven track-record in solving tough vibro-acoustic challenges. Besides his tremendous experience in vibro-acoustics, he is innovative and very effective in defining and developing tools and simulation processes to improve the vibro-acoustics performance during product design and development. Denis is also very good at communicating, when listening to Denis, whether during a conversation or a presentation, even if highly technical, it is always very accessible and seems so easy to understand. Denis is a very nice person to work with, he always shows a high work ethics and sets the bar high. I’d definitely recommend Denis to anyone needing assistance in vibro-acoustics
