Radiation mode–based microphone array: Experimental verification [PDF]

open access: yesJASA Express Letters
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.

Design exploration and performance strategies towards power-efficient FPGA-based achitectures for sound source localization [PDF]

open access: yes, 2019
Many applications rely on MEMS microphone arrays for locating sound sources prior to their execution. Those applications not only are executed under real-time constraints but also are often embedded on low-power devices.

Computation of spherical sector harmonics norm with application to blind source separation [PDF]

open access: yesJASA Express Letters, 2023
Spherical microphone arrays (SMAs) are widely being used for source localization and separation. However, it is uneconomical to build a full SMA when sources are present in restricted regions of environment.
