An Improved Sound Source Location Method for MEMS Microphone Array
MEMS (Micro Electro Mechanical System) microphone array is the most commonly used microphone array selection at this stage. However, in actual use, the microphones cannot receive omnidirectional audio signals, when they are soldered on the other side of the PCB. Therefore, for the practical application of MEMS microphone array, this paper proposes a new microphone array receiving signal model, and improves the traditional beamforming algorithm, in order to improve the resolution of MEMS microphone when receiving signals at small angles. At the same time this paper built a practical test system to verify the reliability of the new model.
