NVH & Acoustics for Hybrid & Electric Vehicles

NVH & Acoustics for Hydrid & Electric Vehicles

Electric and hybrid electric vehicles drastically reduce CO2 emissions, but bring their own NVH and acoustic challenges. 

Our integrated solutions optimize electrical motor noise behavior while leaving electromagnetic performance unchanged. They integrate electric power sources in the driveline while ensuring smooth operation with minimum NVH impact. Our tools and services help you balance NVH and ride comfort with body weight.

Ensuring acoustic comfort of hybrid and electric vehicles means tackling a host of new phenomena. An electric motor often generates annoying high-frequency tonal noises, while hybrid powertrains provoke transient noise. Traditional noise sources, such as road noise and wind noise, become more prominent without the masking noise of an internal combustion engine. Additionally, new noise sources that went unnoticed in the past need to be considered, such as HVAC, battery cooling, and steering systems.

Our integrated solutions combine engineering services and the best of simulation and testing tools to help EV and HEV manufacturers and suppliers deliver superior NVH and acoustic performance of the electric drive, battery, and full vehicle.
