A processor receives the microphone signals and applies a first set of filters to a subset of the plurality of microphone signals from each of the arrays, the first set of filters inverting the signals below a cutoff frequency, and provides the first-filtered signals and the remainder of the microphone signals from each of the arrays to a second set of filters. The processor uses the second set of filters to combine the signals to generate a far-field signal that is more sensitive to sounds originating a short distance away from the earphones than to sounds close to the earphones above the cutoff frequency, and omnidirectional below the cutoff frequency, determines a level of wind noise present in the microphone signals, and adjusts the cutoff frequency as a function of the determined level of wind noise."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Controlling wind noise in a bilateral microphone array","description":"A pair of earphones have microphone arrays each providing a plurality of microphone signals.
