Developing a noise cancellation solution for headsets and hearables

CEVA, licensor of signal processing platforms and artificial intelligence processors for smarter, connected devices, and Silentium, a provider of Active Noise Cancellation (ANC) technology and adaptive sound management solutions, have announced that the companies have partnered to deliver a low power active noise cancellation solution for headsets and hearables.

CEVA and Silentium will showcase a headset reference design based on this solution at CES 2018, January 9-12 in Las Vegas.

For consumers constantly looking for an improved experience from their wireless headsets, earbuds and hearables, Active Noise Cancellation is a must-have feature. Headset chip developers require a flexible solution to suit their specific product needs and Silentium’s software-based algorithms coupled with CEVA’s programmable DSP deliver this flexibility, within the stringent power budget of a portable product.

The solution is based on a CEVA-TeakLite-4 implementation of Silentium’s acclaimed Broadband P2P ANC technology which enhances the personal audio experience. The P2P solution supports broadband fully adaptive ANC technology up to 1KHz and licensees can choose from feedforward, feedback or hybrid systems for their desired application.

“The CEVA-TeakLite family of DSPs are broadly adopted in wireless headsets and hearables, thanks to its ideal blend of power, performance and footprint for small form factor use cases,” said Amit Grauer, senior director of business development at Silentium.

“Our active noise cancellation technology delivers a premium experience and together with CEVA, we offer a highly compelling ANC solution to its audio/voice DSP licensees.”

“Silentium’s Broadband P2P ANC technology offers a tremendous value add with its demonstrable improvement in sound quality when implemented on our audio/voice DSPs,” said Moshe Sheier, director of strategic marketing at CEVA. “The flexibility to tailor the solution for a specific use case is something our customers truly value and we’re delighted to extend our sound ecosystem with this exciting technology.”
