The absence of the internal combustion engine (ICE) changes the signature of the interior cabin noise dramatically. The most obvious game changer is the fact, that the withdrawal of the traditional powertrain unveils the other noise contributors.
The trend towards electrical vehicles poses both challenges as well as opportunities for car developers. The absence of the internal combustion engine (ICE) dramatically changes the signature of the interior cabin noise.
The most obvious game-changer is the fact that the withdrawal of the traditional powertrain unveils the other noise contributors or make them more audible and prominent.
In 2011, G. Goetchius (Leading the Charge – The Future of Electric Vehicle Noise Control, Sound & Vibration) estimated the noise contributors in ICE vehicles and predicted the noise morphology in the electrical ones.
According to this publication, back then, in the traditional ICE vehicles, the biggest noise contributor is the powertrain, followed by the road, wind, and ancillary system noise. While in electrical vehicles, road noise and wind are the most dominant noises. And what’s more, the new structure reveals noises that were originally masked by the combustion engine (such as ancillary system – whine gears, steering rack, air conditioning system, wipers, ABS module, pumps, etc.).
