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.

What is the Power of Noise Analysis Software in the Development of Electrified Vehicles?

Today, it is possible to detect and solve any exterior and interior acoustics problems upfront in the development cycle, using digital tools that leverage Finite Element Methods (FEM), Ray tracing and more, covering log and high frequencies. Organizations like Audi, Bentley, Nissan, and the US Army are already harnessing the convenience of a digital vehicle test facility.

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.
