Welcome to


dBPorous is where you can build/expand your own NVH materials database and increase your simulation accuracy while maintaining low acquisition cost.

You can also import your existing material properties in our platform and use all its functionalities to store, show, compare and download any material data.

You want the utmost security level for your NVH data? Choose "dBPorous On-Premise" and share your NVH data with your colleagues worldwide through your company secure servers.

Can't find what you need?

Join dBPorous and tell us which materials you would like to get. We can contact manufacturers directly and get them to join as well. The more a material is requested, the more chance it has to be added to our database quickly.

" 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. "

How do you want to use dBPorous?

On the web? On your internal company servers (On-Premise)? Or a mix of the two?

dBPorous offers not only the possibility to buy high quality and low cost material properties of NHV products but it also offers a framework where you can store/view/compare/edit your purchases.
Furthermore, you can include your own material properties accumulated over the years into dBPorous and make them available to your NHV simulation teams around the world.

On the Web

Process Subscribe

dBPorous on the Web follows a 3-step process: Subscribe-Shop-Download. 1) Get tokens from a subscription plan, 2) Use these tokens to buy material properties of available materials in database and store in MydB, 3) download the properties from MydB in the form of a lab report and your favorite CAE software material card. Your data is ready to be used into NVH numerical models.

Furthermore, you can import your own company material properties into your secure company section in dBPorous on the Web and make these properties available to your NHV simulation teams around the world.

On-Premise and Web

Process Subscribe

dBPorous On-Premise and Web follows a similar process as the web version, however your company data is more secure since the MydB section is directly located onto your internal company servers. This option therefore offers added data security and the ability to purchase material properties from dBPorous On the Web and importing these into your internal company server.

Furthermore, you can import your own company material properties into dBPorous On-Premise and share with your NHV simulation teams around the world through your company network.

dBPorous On-Premise offers the maximum security dBPorous can offer. The MydB section is installed on your internal company servers and normally do not allow your employees the ability to import data from dBPorous on the Web. However, if needed, your dBPorous On-Premise admin can import data from dBPorous on the Web as an ad-hoc solution.

Furthermore, you can import your own company material properties into dBPorous On-Premise and share all data with your NHV simulation teams around the world through your company network.
