US 2025/0078800 A1 · NON-COHERENT NOISE REDUCTION METHOD AND NON-COHERENT NOISE REDUCTION DEVICE

Abstract

A non-coherent noise reduction method, comprising: (a) receiving a plurality of input audio sensing signals by a processor, wherein the input audio sensing signals correspond to a plurality of channels responsive to sensing by a plurality of audio sensors; (b) detecting whether non-coherent noise exists in at least one of the channels by a non-coherent noise detector; (c) estimating at least one noise power of the non-coherent noise by a noise power estimator, if the non-coherent noise exists in at least one of the channels; (d) deriving at least one noise contour of the non-coherent noise by a noise contour estimator, if the non-coherent noise exists in at least one of the channels; and (e) enhancing the input audio sensing signals according to the noise power and the noise contour if the non-coherent noise exists in at least one of the channels.
