Abstract
A headset and a method configured to process audio signals from multiple microphones, comprising: a first pair of microphones () outputting a first pair of microphone signals and a second pair of microphones () outputting a second pair of microphone signals; a first near-field beamformer () and a second near-field beamformer () each configured to receive a pair of microphone signals and adapt the spatial sensitivity of a respective pair of microphones as measured in a respective beamformed signal (X; X) output from a respective beamformer (); wherein the spatial sensitivity is adapted to suppress noise relative to a desired signal; a third beamformer () configured to dynamically combine the signals (X; X) output from the first beamformer () and the second beamformer () into a combined signal (X); wherein the signals are combined such that signal energy in the combined signal is minimized while a desired signal is preserved; and a noise reduction unit () configured to process the combined signal (X) from the third beamformer () and output the combined signal such that noise is reduced.
