Ansys Sound enables you to listen to, analyze and design sound sources based on real acoustics measurements or acoustic simulation results (CAE NVH).
Ansys Sound is a post-processing tool that allows engineers to analyze and optimize their product noise using desired sound quality criteria and listening tests. Innovative time-frequency analysis and processing functions are available for isolating and modifying sound components and assessing the influence of sounds on human perception. Ansys Sound reproduces the 3D sound in-simulator and in-vehicle, including tools to tune Active Sound (ICE) or electric vehicles (EVs).
Define meaningful vibro-acoustic specifications, targets, and acceptance thresholds using Ansys Sound's powerful post-processing capabilities. Special tools are dedicated to E-Motor noise, aeroacoustics sources, virtual reality 3D sound, and more.

In 2023 R1, Ansys Sound software updates include translating vibration data into acoustics data, updates to the Virtual Reality Sound (VRS) module, and improved methodologies for generating interactive sounds for electric vehicles.
New differentiation tools allow users to convert vibration data to velocity data to displacement data and determine if they are above or below acceptability ranges.
A new application within the Virtual Reality Sound (VRS) module allows users to accurately play multichannel sound files on multiple speakers, making the sound comparison as easy as possible.
A new sound design method, granular synthesis, allows users to rapidly sketch and tune rich active sounds from a single sound sample for electric vehicle applications.
Sound is everywhere. And the stakes are high, as global competition tightens and social media influences purchasing decisions.
Developers face challenges of predicting and optimizing the sounds products will make in real-world applications. If they wait for the physical prototyping stage to assess acoustic effects, it may be a time-consuming, expensive fix to address issues, potentially leading to a poor user experience and possible damage to brand reputation. Using Ansys Sound, you get a post-processing tool to enable the prediction of noise and vibrations assessed at the earliest stages of virtual product modeling.
Combine this with other Ansys solutions to make immediate acoustic improvements to eliminate the time and costs of late-stage rework without over-engineering your design. By replacing guesswork with fact-based acoustic engineering assessments, companies in every industry can create signature sounds to reinforce their brand reputation, generate revenue and build long-term customer loyalty.
Ansys Sound is the premier software solution for sound design, sound analysis and sound quality. The solution offers an innovative post-processing tool to predict and assess noise and vibration via human hearing, from the earliest stages of virtual product modeling or based on a given measurements database. It is able to link sound to driving simulators, flight simulators and virtual reality platforms.
Ansys Sound paves the way to target sound definition, brand sound creation, subjective and objective measurement, component separation, and troubleshooting.
Listen to the acoustic simulation, analyze recording, optimize sound quality, reproduce 3D sounds, and design active sounds
Enable the filtering and comparison of sound signals and separate the signals into several components based on state-of-the-art algorithms that capture de-noising, tonal components, transient parts extraction and the mixing of all components. It is possible to track and isolate whistling, whine and any other pure or harmonic frequency. Shocks, ticks, clicks, explosions and every kind of impulsive sounds can be isolated using the transient detection component of the sound module within Ansys Sound.
Explore the possibilities of detection or association of an RPM profile to a signal and calculation of order analysis. The RPM signal can be derived from a recorded tachometric signal or pulse signal. Or, extract and create using the integrated tools within Ansys Sound for harmonics detection in the time frequency representation. The power of these tools doesn’t require a specific sensor device, such as a rev counter, to carry out harmonic order analysis; for E-Motor you can also isolate with few clicks, the PWM (pulse width modulation) tones.
You can listen to the sound from the acoustic simulation of an electric motor dynamic model and then modify sounds to evaluate effects of level changes on components, all while running a study on sound quality.
Joint research involving teams from Ansys and the CNRS LMA research laboratory are used for quantifying impulsive sounds’ loudness. The psychoacoustic feature of Ansys Sound can perform the equalization of a set of signals to reach a specific common indicator, for loudness equalization.
Get valuable and reliable user feedback about the sound of your products, from sound quality, user preferences, sound positioning or unpleasantness studies.
For every sound source, 3D sound techniques are available. To maximize the realism of the sound, the loudspeaker setup can match the customer’s facilities. Additionally, an on-site calibration and equalization can be performed to achieve optimal realism in the simulation. Even with the output signal through a pair of speakers, the listener has the sensation of being immersed in the real-world sound scene while experiencing a high-quality reproduction of the original soundscape in timbre and spatial position. Sound offers many different techniques such as Binaural, Transaural, VBAP, Ambisonics techniques with multiple speakers set up or Headphone, with or without headtracking.
This includes powertrain (ICE, Hybrid or EV), aerodynamic noise, rolling noise, screeching tires, HVAC, traffic and more, offering an advanced real-time audio synthesis tool for a generation of car-related sounds. Sound is designed to integrate into driving simulators and virtual reality platforms. With an open database, customized car sounds can be created and integrated into the software. The software’s synthesis technique consists of generating sound sources according to real-time events within a given scenario, so when the driving conditions change, the synthesis algorithms match the new conditions, and each sound source evolves accordingly. With the loudspeaker set up to match the customer’s facilities and on-site calibration and equalization, achieve optimal realism.
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.
