Simultaneous asynchronous microphone array calibration and sound source localisation [PDF]
, 2015 © 2015 IEEE. In this paper, an approach for sound source localisation and calibration of an asynchronous microphone array is proposed to be solved simultaneously. A graph-based Simultaneous Localisation and Mapping (SLAM) method is used for this purpose.

Instability waves in a subsonic round jet detected using a near-field phased microphone array [PDF]
, 2006 We propose a diagnostic technique to detect instability waves in a subsonic round jet using a phased microphone array. The detection algorithm is analogous to the beam-forming technique, which is typically used with a far-field microphone array to ...

Effect of Vertical Microphone Layer Spacing for a 3D Microphone Array [PDF]
, 2014 Subjective listening tests were conducted to investigate how the spacing between main (lower) and height (upper) microphone layers in a 3D main microphone array affects perceived spatial impression and overall preference. Four different layer spacings of

Microphone Array Geometries for Horizontal Spatial Audio Object Capture With Beamforming
Journal of The Audio Engineering Society, 2020 Microphone array beamforming can be used to enhance and separate sound sources, with applications in the capture of object-based audio. Many beamforming methods have been proposed and assessed against each other.

Acoustic source localization using the open spherical microphone array in the low-frequency range [PDF]
MATEC Web of Conferences, 2019 Recently, spherical microphone arrays (SMA) have become increasingly significant for source localization and identification in three dimension due to its spherical symmetry.

Localization of planar acoustic reflectors from the combination of linear estimates [PDF]
, 2012 In this paper we present a simple yet effective method for estimating the geometry of an acoustic enclosure in three-dimensions. By capturing the acoustic impulse responses using a microphone array and a loudspeaker at different spatial locations we ...

Lightweight and Optimized Sound Source Localization and Tracking Methods for Open and Closed Microphone Array Configurations [PDF]
Robotics Auton. Syst., 2018 Human–robot interaction in natural settings requires filtering out the different sources of sounds from the environment. Such ability usually involves the use of microphone arrays to localize, track and separate sound sources online.
