COMSOL, the multiphysics and acoustics simulation software company, and HEAD acoustics, a leading provider of integrated acoustic measurement, analysis, and optimization solutions, join the AES Audio Product Education Institute in a webinar focusing on exploring multiphysics simulation and testing practices.
The ability to predict and understand spatial responses of speaker and microphones is important when developing modern consumer audio products. And because feedback and echo cancellation plays an important role in these products, the webinar will also explore echo and double talk testing, including different echo metrics that are used in voice quality testing.
Providing another learning opportunity on the use of simulation and measurement solutions for audio product design, the two companies will share their experiences in separate sessions, followed by time for questions.
Echo cancellation, and the ability to predict and reduce feedback in the transmission path from source to receiver is very important. In his session, Mads Herring Jensen (Technology Manager, Acoustics for COMSOL) will explain ways to model both the source and the receiver responses, using techniques such as reciprocity, as well as the full feedback path. Early assessment is important as DSP algorithms can then be developed and fine-tuned before any physical prototypes are made.
In a separate presentation, Jacob Soendergaard (Telecom Account Manager, HEAD acoustics), will address the different echo metrics that are used in Voice Quality testing as well as double talk analysis techniques. Topics to be covered include the definition of echo, how does delay affect echo, different metrics used to characterize echo, what is double talk, and why it's important metric. Finally, the presentation will review the different analysis techniques used to quantify double talk.
This event will be presented by COMSOL. Following the opening remarks and the two presentations there will be opportunities to ask questions. In general, attendees will expand their understanding of the use of multiphysics simulation in audio product design, addressing virtual prototyping, testing, measurement, and optimization.
This webinar from the Audio Product Education Institute underscores the AES’s commitment to providing its membership and the industry at large with information on real-world solutions for audio product development.
