The internal sensor measures acoustic signals propogating internally to a user's head. The external sensor measures acoustic signals propagating externally to the user's head. The method includes: producing first and second audio signals by measuring simultaneously acoustic signals reaching the internal and external sensors, respectively; filtering the second audio signal by a noise matching filter matching a second noise signal affecting the second audio signal with a first noise signal affecting the first audio signal, wherein the first noise signal and the second noise signal correspond to a same noise acoustic signal originating outside the user's head and measured by respectively the internal and external sensors, thereby producing a filtered second audio signal including a matched second noise signal; and mixing the filtered second audio signal and the first audio signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio signal processing method and system for noise mitigation of a voice signal measured by an audio sensor in an ear canal of a user","description":"Disclosed is an audio signal processing method implemented by an audio system with internal and external sensors.
