Visualization of Broadband Sound Sources

open access: yesMATEC Web of Conferences, 2016
In this paper the method of imaging of wideband audio sources based on the 2D microphone array measurements of the sound field at the same time in all the microphones is proposed. Designed microphone array consists of 160 microphones allowing to digitize

Higher order differential-integral microphone arrays

open access: yesThe Journal of the Acoustical Society of America, 2010
This paper develops theory to design higher order directional microphone arrays. The proposed higher order designs have similar inter sensor spacings as traditional first and second order differential arrays. The Jacobi–Anger expansion is used to exploit the underlying structure of microphone signals from pairs of closely spaced sensors.

Practically Efficient Blind Speech Separation Using Frequency Band Selection Based on Magnitude Squared Coherence and a Small Dodecahedral Microphone Array

open access: yesJournal of Electrical and Computer Engineering, 2012
Small agglomerative microphone array systems have been proposed for use with speech communication and recognition systems. Blind source separation methods based on frequency domain independent component analysis have shown significant separation ...
