Radiation mode–based microphone array: Experimental verification

Year: 2024

Type: article

Abstract: The mouth of a speaker is generally close to the microphones of speech communication devices, such as headsets and phones, whereas noise sources are more distant from the microphones. Hence, near-field enhancement using microphone arrays is a promising strategy for noise suppression. This study deals with radiation mode-based microphone arrays and mainly focuses on experimentally validating the methodology. Because the radiation mode-based microphone array can be approximated as a gradient microphone, the difference between them and the advantage of the former over the latter are clarified by comparing the beampatterns.
