New vehicle designs, especially EVs, are far from traditional vehicle designs and must be ready to meet evolving regulations. Acoustic challenges arise from the need for interior sound packages to meet brand, weight, and noise comfort specifications. An accurate and early assessment of noise contributions from sources such as powertrain, air induction, and exhaust systems iskey for the accurate prediction of interior noise.
By using ESI's Virtual Proving Ground for Acoustic Performance, engineers create a pleasant journey with superior sound quality by removing undesired interior and exterior noise - fully digital: From excitation to sound radiation, and through different transmission paths, virtually test the acoustic performance of your car’s design. Work in a virtual test track to get new designs right the first time while eliminating costly physical prototype tests for sound quality analyses.

Predicting Aeroacoustic Performance in Luxury Vehicles: Bentley Motors and ESI's Simulation Approach for Exceptional Acoustic Environments
Luxury vehicles prioritize quality and refinement, and the increasing use of electrification in the automotive industry has highlighted the importance of aeroacoustics in sound perception. Accurately predicting a vehicle's aeroacoustic interior noise is crucial for creating exceptional acoustic environments, and simulation can offer an optimal solution. Bentley Motors and ESI's approach outlined in an SAE technical paper serves as a guideline for predicting a vehicle's aeroacoustic performance, allowing OEMs to remove physical prototype testing early on and reducing the risk of costly design changes.
Achieve optimal acoustic performance in every aspect of your electric vehicle design with the VA-One simulation software
Watch the webinar on demand and find out how you can deliver electric vehicles that not only prioritize sustainability - but also excel in acoustic performance.
You will learn more about 5 key features of VA-One, acoustic simulation software, empowering EV manufacturers to meet their acoustics performance targets for electric vehicles including: Pass-by Noise, Acoustic Vehicle Alerting System (AVAS), Sound Package Design and Optimization, Wind Noise and Auralization.
By using Virtual Prototyping, Bentley succeeded in what we set out to do –optimize every component of the Flying Spur firstly in the virtual world before we create physical parts. At the same time, we have reduced physical prototypes, creating the quietest in-cabin experience for our customers. Virtual Prototyping means fewer prototypes have to be built, and we reduce our testing mileage. It also helps influence the design and engineering of the car at an early stage and affords significant benefits in the extensive testing phase.
