What's New?

For 2022 R1, Ansys VRXperience Sound will be officially renamed to Ansys Sound. For this release, the focus is around improved sound quality and design for our users, including:

  • A color map display for the ISO 532-1 standard so users can immediately check the time (or RPM) and frequency to ultimately reduce noise annoyance.
  • Fully released FRF (Frequency Response Function) capability allows users to characterize the transfer function of a system by estimating frequency response and minimizing the effect of noise at the receiver. Results can be transferred to Fluent to filter a simulation result for a more robust analysis.
  • Optimize acoustic performance and reduce noise annoyance with tonality indicators that can be calculated in display order with the ability to switch order levels. This is especially of interest to customers working with rotating machinery.

Active Sound Design for Automotive

Active Sound Design technologies can create an atmosphere to make the vehicle more alive, more attractive and safer thanks to audio feedback while driving. This is used for ICE engine cars and EV, including AVAS and ADAS sound.

From component-level acoustic simulation to system-level sound rendering
