Designing a feedback ANC headset using AS3435
Feed-forward headsets typically are more easily developed because the design engineer usually does not have to deal with stability issues. A major drawback of this topology, however, is wind noise because the ANC microphones are directly exposed to the ambient. An alternative that overcomes this drawback is the use of a feedback ANC technology. This article describes the development steps necessary to design a feedback ANC headset based on the AS3435 from ams AG.
