Dynamic Feedback Cancellation

Syncro's two-stage DFC system eradicates feedback before it can develop into whistling. Unlike traditional systems, which reduce gain to eliminate feedback (at the risk of losing speech information), Syncro uses precise digital phase cancellation. This completely avoids reduction of gain and distortion of the signal.

Two stage operation
The continuous, slow-acting stage reacts to slow and gradual changes in the feedback path (e.g. the ear mold changing position during daily activities), ensuring consistently high sound quality.

The fast-acting stage reacts to abrupt changes in the acoustical environment that would normally result in feedback (e.g. holding a phone to the ear). Besides eliminating feedback, the DFC system facilitates the implementation of OpenEar Acoustic
