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.
JULY 2023
In 2023 R2, advancements have been made to Ansys Sound software, including more significant integrations with other Ansys products, new sound source availability, and a more enhanced user interface (UI).
Ansys Sound features exposed in DPF for Python and C++ allow users to automate previously manual tasks, including automation of order isolations and psychoacoustic metrics.
Motion CAE files can now be sent directly to Ansys Sound for post-processing and acoustics analysis.
Ansys Sound Design for Electric Vehicle (ASDforEV) software is now compatible with NI CAN-reading devices.
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是用于声音设计、声音分析和声音品质研究的重要软件解决方案。该解决方案提供了一套创新的后处理工具，可以基于初期的虚拟建模仿真或基于已有的测试数据库，从人耳真实听感出发预测和评估噪声和振动。 它能够将声音连接到驾驶模拟器、飞行模拟器和虚拟现实平台中。
Ansys Sound为目标声音定义、品牌声音创建、主观和客观声学测试、声音成分分离和故障排除奠定基础。
聆听声学仿真、分析声音采集、优化声音品质、再现3D声音以及设计主动声音
支持声音信号的滤波和比较，并基于先进的算法将信号分离为多个分量，算法可实现跟踪降噪、音调分量识别、瞬态部分提取和不同声音分量的混合。可以跟踪和隔离口哨声、呜呜声和任何其他纯音调或谐波频率。使用Ansys Sound中的瞬态声音检测模块可以分离出抖动声、嘀嗒声、咔嗒声、爆炸声和各种脉冲声。
可以实现RPM转速信号识别，原始信号的关联和阶次分析计算。RPM转速信号可从记录的转速信号或脉冲信号中获取。或使用Ansys Sound中集成的工具进行提取和创建，以实现在时间-频率分析瀑布图中中进行谐波阶次的识别。这一系列工具的强大之处是不需要依赖特定的传感器设备（例如转速计）来开展谐波阶次的分析；对于电机产品，您还可以简单点击几下鼠标来提取脉宽调制（PWM）引起的音调成分。
您可以从电机动力学模型的声学仿真中聆听声音，然后修改声音以评估组件声压级变化声音感受的影响，于此同时声品质的研究也可以同时进行。
Ansys团队和CNRS LMA研究实验室一同参与的联合研究用于量化脉冲声音的响度。Ansys Sound的心理声学功能可以对一组信号进行均衡处理，以满足特定的公用指标，实现响度均衡。
从声品质、用户偏好、声音定位或不适度的研究中获得有关产品声音的有价值和可靠的用户反馈。
对于每个声源，均可使用3D声音技术。为了最大限度地提高声音的真实感，可以匹配客户的设施进行扬声器的软件设置。此外，还可以执行现场校准和均衡处理，从而在虚拟模拟器中实现最好的逼真度。即使是通过一组扬声器输出的声音信号，听众也会有沉浸在真实声音场景中的感觉，同时在音色和空间位置上体验原始声音场景的高质量渲染再现。Sound提供了许多不同的3D声音技术，如双耳双声道、双扬声器跨声道、VBAP或Ambisonics技术，实现设备可以是多个扬声器或耳机（可以匹配或不依赖头部跟踪功能）。
这些包括音源包括传动系统（ICE、混合动力或EV）、空气动力学噪音、滚动噪音、轮胎尖叫声、HVAC空调噪音、交通环境噪音等，组成了先进的汽车相关声音的先进实时音频合成工具。Sound能够快速集成到驾驶模拟器器和虚拟现实平台中。通过开放的数据库，用户可以创建定制化的汽车声音并将其集成到软件中。该软件的合成技术包括根据给定场景中的实时事件生成声源，因此当驾驶条件发生变化时，合成算法会与新条件相匹配，每个声源也会相应地发生改变。将扬声器设置为与客户的实际设施相匹配，并进行现场校准和均衡处理，从而实现最佳逼真度。
主动声音设计技术可以通过驾驶时的声音反馈营造车内声音氛围，使车辆变得更有活力、更具吸引力和更安全。这一技术适用于内燃机汽车和电动汽车，包括AVAS和ADAS声音。
