This abstract first appeared for US patent application 18243772 titled 'WEARABLE AUDIO DEVICES WITH ENHANCED VOICE PICKUP
Original Abstract Submitted
A wearable two-way communication audio device includes a first microphone that provides a first microphone signal, a second microphone that provides a second microphone signal, and one or more processors. The one or more processors are configured to use the second microphone signal to estimate an ambient noise level and adjust an equalization filter based on the estimated ambient noise level. The first microphone signal and the second microphone signal may be processed via a first beamformer to provide a first beamformed signal and the first beamformed signal may be filtered with the equalization filter to provide a noise estimate signal. The one or more processors may also use the noise estimate signal to generate a voice output signal for transmission to a far end recipient.
