Abstract
A wind noise reduction system including a beamformer, a comparator, and a voice mixer is provided. The beamformer may be an MVDR beamformer, and generates a beamformed signal based on a first microphone signal and a second microphone signal. The comparator generates a comparison signal based on the beamformed signal and a wind microphone signal. The comparison signal may be further based on a beamformed energy level of the beamformed signal and a wind energy level of the wind microphone signal. The voice mixer generates an output voice signal based on the beamformed signal, the wind microphone signal, and the comparison signal. The wind noise reduction system may further include a wind microphone corresponding to the wind microphone signal. The wind microphone may be arranged on a portion of a wearable audio device configured to be seated in a concha of a wearer.
