Comparative analysis and selection of the geometry of the microphone array based on MEMS microphones for sound localisation

Радіоелектронні і комп'ютерні системи
The subject of this article is the design and optimization of the geometric configuration of omnidirectional MEMS microphone arrays for sound localization tasks. The goal is to determine the most effective array architecture and beamforming algorithms to

Three-dimensional microphone arrays [PDF]

The Journal of the Acoustical Society of America, 1987
Low-cost, high-quality microphones and integrated electronics prompt examination of sophisticated arrays for sound pick-up in large enclosures. A three-dimensional, uniform configuration of receivers is studied and shown to have several benefits. Beamforming and delay steering can be accomplished over the 4π solid angle without spatial ambiguity ...

An online algorithm for echo cancellation, dereverberation and noise reduction based on a Kalman-EM Method

EURASIP Journal on Audio, Speech, and Music Processing, 2021
Many modern smart devices are equipped with a microphone array and a loudspeaker (or are able to connect to one). Acoustic echo cancellation algorithms, specifically their multi-microphone variants, are essential components in such devices.

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

JASA 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.

Chinese Traditional Musical Instrument Evaluation Based on a Smart Microphone Array Sensor

Proceedings, 2019
For Chinese traditional musical instruments, the general subjective evaluation method by experts is not cost-effective and is limited by fewer and fewer experts, but a clear physical law is very hard to established by physicists.
