International Congress : NVH Comfort
- 14 & 15 October 2020
- Le Mans
Introduction
This congress is the first one in collaboration with CAERI.
Dear colleague,
The 2020 edition of SIA Automotive NVH Comfort conference, organized by SIA and CTTM, will take the place on 14th and 15th October in Le Mans, France. In order to increase the international impact, the 2020 conference is organized in collaboration with CAERI State Key Laboratory of vehicle NVH and safety Technology, which is one of the principal Chinese partners of SIA.
As all the previous editions, the 2020 NVH conference, will address a specific topic, which presents a major interest for the automotive NVH community. This time, we would like to address « Automotive noise, regulation and urban soundscape ».
With over 50% of mankind living in urban and suburban area, the question of noise exposure is leading to more and more stringent noise regulation, along with a need to adapt to the specific noise signature of new technologies for safety issues (AVAS for Electric vehicles). Those regulations are aiming for a progress in the quality of life, an improvement of health and safety and to protect the environment. It is therefore necessary for NVH automotive engineers to better understand the regulatory aspects of noise in the environment, and the reality and challenges of modern soundscapes to ensure that those goals are met.
The automotive acoustic community would like to address the following issues:
- is the vehicle noise the principal nuisance source in urban area ?
- what is the influence of the environment on transportation noise (road surface, green areas, vegetal green walls, …) ?
- is the actual noise regulation strategy appropriate to limit the real impact of vehicles to urban noise ?
This particular edition will be therefore centered on citizen perception: as a pedestrian exposed to traffic and vehicle charging noise, as a driver or a passenger in a car, and will cover the necessary technical challenges manufacturers are facing today: lightweight design, impact of new technologies and driver experiences, audio sound design and the necessary changes in methodology and approaches. With autonomous vehicle on its way, the driving experience will dramatically change: how shall we design for NVH when everyone in the car will be a passenger, what are the right tradeoffs between driving comfort and NVH? Moreover, this year we would like to create a special session concerning the vibrational drive comfort of vehicles and its interaction with the NVH. Consequently, the papers dealing with tradeoff between NVH and driving comfort issues are particularly welcome.
Join us to make a huge success of the 2020 Automotive NVH Comfort Conference in Le Mans, France!
