The dBPorous team is thrilled to announce its partnership with Quiet Consult, a numerical simulation consulting firm lead by Jonathan Jacqmot.

Quiet Consult aims at supporting industries in their efforts to mitigate noise & vibration through an impactful partnership that guarantees results and opens doors to enhancements. Quiet Consult o...ffer two complementary services: i) Directly managing acoustic aspects during product design and ii) Facilitating the integration of methods for independent acoustic management.

Before launching Quiet Consult, Jonathan was a Senior Director at Hexagon (MSC Software) Acoustic and NVH Department. He has 20+ years of experience in acoustics and the NVH market with 200+ project as projet manager.

Jonathan will help promote dBPorous and increase adoption of users and manufacturers to our solution.

dBPorous is a unique commercial NVH database tool providing highly accurate NVH properties of foam, fibers, viscoelastic and metamaterials.

To build accurate NVH predictive simulation models of cars, airplanes, train cabins and the like, one has to properly represent the geometry of the structure, the acoustic fluid and the sound package. Furthermore, the model must contain accurate physical properties of the material used. Those physical properties are readily available for the struct...ural elements but it is not the case for the sound package. When Biot parameters of various foams and fibers are not available, NVH engineers must “guestimate” the values and this can cause the predictiveness quality of the models to go down significantly. But how much of a risk are we taking by not knowing the physical properties of these NVH materials?

This paper studies the effect of uncertainties of the Biot parameters on transmission loss and surface absorption. The method used in this paper rank the main sources of uncertainties of the response and can therefore identify the material properties that a NVH simulation engineer must know with precision to ensure his models are accurate and predictive in nature.

The European Automotive Noise Conference

The worldwide economical and geo-political developments in the last decennium, including the breakout of the COVID pandemic, have made clear that a change of course has become absolute priority. In order to assure stable and sustainable long-term growth, the new political str...ategies must be inclusive in the sense that they must reconcile economic, environmental and social goals.

A green circular economy that includes the eco-system and human well-being is also the focus of the European Commission for the coming years, a vision that is shared by VIRTUAL VEHICLE and reflected by the adapted structure of our research areas. The reduction of noise pollution due to ground transportation in urban environments, the development of competitive acoustical materials which are compatible with the recycling needs and the development of technologies which can assure better access and integration of all groups of the population to the new technologies are examples of the tasks awaiting the NVH community.
