Representatives of Xperi and the National Association of Broadcasters will share what they’ve learned about electromagnetic interference in electric vehicles and its impact on AM radio audio at an upcoming Audio Engineering Society event.
Pooja Nair and Ashruf El-Dinary of Xperi will join David Layer of NAB discussing the issue.
The effects of EMI are more pronounced in electric vehicles and is particularly disruptive to AM reception. Nair has written that AM HD Radio signals are more resistant to EMI than their analog counterparts, and that advanced DSP and digital communications techniques make those signals more robust than analog AM signals, especially in all-digital MA3 mode.

The AES 2022 International Automotive Audio Conference will take place June 8–10 in Detroit.
The conference covers such topics as automotive acoustics, virtual speaker integration, modeling and measurement, system architecture and hardware, and supply chain and sourcing issues. The target audience is audio professionals engaged in the development of vehicle sound systems.
A keynote from Dirac Research’s Mathias Johansson will address “The Automotive Industry Transformation and the Demand for High In-Car Audio Quality,” while Dolby’s Andreas Ehret will address “Immersive Audio Experience in Automobiles.”
Companies represented on the event committee include JJR Acoustics, Panasonic, Dirac, Harman, IAV, Nissan and Ford. The schedule of events is available online.
Conference Chair Roger Shively said in the announcement, “Understanding the science and technology applied to automotive sound systems in today’s vehicles, and to the design of advanced infotainment and communication systems of tomorrow, requires exploration of acoustics, DSP processing, test and evaluation, and the full span of additional specialties.”
