Optimizing Interior Noise for Electric Vehicles
pgw [at] esi-group.com
Electric Vehicles represent new acoustic challenges to automotive designers. The absence of the internal combustion engine with exhaust and air intake systems results in more dominant noise contributions from traditional sources such as tires and aero dynamics. Electric motors and ancillary systems such as Pumps, HVAC, Battery Cooling Systems, Compressors etc along with new noise transmission paths through battery compartments add to these challenges.
Vehicle interiors must be redesigned for improved driver / vehicle interaction and the future provision of infotainment systems resulting in investigations of sound bubbles that improve vehicle occupant comfort and speech clarity. Exterior noise legislation responding to concerns about pedestrian safety becomes a critical issue adding to already established Pass By Noise thresholds
Webinar Key Topics:
The vibro acoustic performance of Electric and Hybrid Vehicles present many new challenges to automotive designers, where previously focused on the engine as a dominant noise source for both interior and exterior noise emissions.
- Create predictive models for (H)EV noise performance
- Analyze different noise control treatments
This coupled with the priority of maximizing range through weight reduction means that even long-established automotive players must establish new design methodologies and procedures that can respond to these challenges.
The webinar will be presented by ESI acoustic engineers who have been actively engaged in Electric Vehicle design projects who will present answers to these challenges.
