International Congress : NVH Comfort

  • 7-8 December 2021
  • Le Mans

Postponement of our congress in 2021



This congress is the first one in collaboration with CAERI.


Due to growing concerns and new measures taken by governments and companies regarding the COVID-19, and after consulting the conference’s committee, we would  like to inform you tha


Dear colleagues,


Due to the uncertainties related to the health situation, and in order to put everyone's health first, we regret that we have to postpone our NVH 2020 congress, which was scheduled to take place on October 14 and 15.

We are already looking forward to seeing you in Le Mans next year, 7 - 8 December 2021, for our congress which will then be twinned with the International Sound Biennial of Le Mans.

The initial program was particularly rich. We would like to thank again all the authors, experts and managers who were mobilized for its elaboration. It will simply be updated in order to reinforce even more the expected quality level.

Several companies had planned to exhibit their know-how and innovations. We thank them for their support. Some of them have already confirmed that they are maintaining their commitment for the next edition. This deserves a second THANK YOU.

But we don't want to wait a year before we meet again. We will suggest you other rendez-vous next spring, probably in the form of digital sessions, which will address the major themes of our congress and will contribute to maintain and strengthen the links between NVH experts from the automotive industry and R&D before our great international event in Le Mans.


We look forward to seeing you again.

Until then, take care of yourself.

Hervé Pichon, Hervé Gros with the NVH SIA CTTM Congress Program Committee
