Ansys Sound Acoustic
Analysis and Sound
Design

Ansys Sound enables you to listen to, analyze and design sound sources based on real acoustics measurements or acoustic simulation results (CAE NVH).
Overview

Improve Your Sound Quality and Design

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).

Capabilities

Predict and Assess Noise and Vibration at the Earliest Stages Through Virtual Product Modeling

Ansys Mechanical creates an integrated platform that uses finite element analysis (FEA) for structural analysis. Mechanical is a dynamic environment that has a complete range of analysis tools, from preparing geometry for analysis to connecting additional physics for even greater fidelity. The intuitive and customizable user interface enables engineers of all levels to get answers fast and with confidence.

Ansys Workbench enables robust connection to commercial CAD tools, providing click button design point updates. Seamlessly integrated multiphysics capabilities are available with fluids and electrical solvers.

Capabilities

Structures Capabilities

Easily handle the complexity of varied design environments with a range of analytical tools that enable you to meet performance goals and ensure long-term reliability.

Perform temporal, spectral and time-frequency graphical analysis of sound and induce modifications on the signal.

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.

Work with sounds and signals exhibiting harmonic content and employ tools related to orders of rotating machines.

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.

Listen to Ansys Mechanical, Ansys Fluent, Ansys LS-DYNA and Ansys Motion simulations calculation results and create sound from spectra or waterfall resulting from mechanic, aerodynamic or fluid simulations.

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.

Multiple psychoacoustics criteria are monitored—often required for initial qualification of sound quality— and advanced measurements of these metrics are recorded for listening tests.

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.

Evaluate the sound quality of your product with Ansys Sound, by measuring sound perception through jury testing experiments.

Get valuable and reliable user feedback about the sound of your products, from sound quality, user preferences, sound positioning or unpleasantness studies.

Improve the realism and immersion of a sound by creating soundscapes in virtual reality platforms and driving simulators.

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.

Ansys Sound provides the Active Sound Design (ASD) comprehensive solution for engine sound enhancement (ESE) for electric vehicles (EVs) and internal combustion engine (ICE) cars.

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.

All sound sources get managed and accurately modeled and configured in the included interactive sound generator for driving simulators.

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.

Smart Strategies for Large Structural Simulations

One way to gauge the progress of engineering simulation software is through the lens of size. Engineers today routinely run structural simulations with a few million degrees of freedom, and the largest commercial structural simulations have topped even 100 million degrees of freedom.
