Sound quality and fluctuation sound analysis for improving EV comfort
Passenger cabin sounds have been the focus of NVH and BSR analysis in the automotive industry for years, particularly engine, booming and road noise in internal combustion engine vehicles. However, the shift to electric vehicles (EVs) has changed these targets. Engine and booming noises are now less relevant, while road noise is more prominent in EVs. Additionally, EVs introduce new noise sources, such as inverters and motor electromagnetic noise. Therefore, NVH measurement targets must adapt to these challenges. This presentation will discuss sound quality and fluctuation sound analysis as tools for enhancing ride and sound comfort in modern vehicles.
