Independent Component Analysis Using Spherical Microphone Arrays
Spherical microphone arrays provide a new and promising tool for the spatial analysis of complex sound fields. Considerable previous work has investigated the use of spherical microphone arrays for phase-mode beamforming, which relies on the Bessel-weighted spherical harmonic transform of the sound field. In this paper, we investigate the advantages that spherical microphone arrays provide for ...
متن کاملAcoustic source localization in mixed field using spherical microphone arrays
Spherical microphone arrays have been used for source localization in three-dimensional space recently. In this paper, a two-stage algorithm is developed to localize mixed far-field and near-field acoustic sources in free-field environment. In the first stage, an array signal model is constructed in the spherical harmonics domain. The recurrent relation of spherical harmonics is independent of ...
متن کاملTime-domain Beamforming using 3D-microphone arrays
Acoustic measurements inside any cavity are mostly conducted with a view number of microphones. By this means it is possible to gain information about frequencies, orders, sound pressures. However, a space selective analysis is nearly impossible and it is not feasible to find multiple sound sources position in space in a practical way. Traditional beam forming systems with planar microphone arr...
متن کاملPractical Aspects of the Calibration of Spherical Microphone Arrays
Spherical microphone arrays have been widely studied for acoustic scene analysis and beamforming. Spatial sound field analysis typically requires two distinct steps: A calibration stage equalizes spatio-temporal deviations of the microphones. Then a decoupling stage extracts orthogonal spatial components of the wave field. For spherical microphone arrays, the decomposition of the measured sound...
متن کاملLimitations and Error Analysis of Spherical Microphone Arrays
There has been a strong interest in theory and design of spherical microphone arrays in recent years due to their possible use in recording directional sounds for surround sound creation. The theory of such arrays is based on decomposition of sound fields to spherical harmonics which are the natural basis functions for valid sound fields over three dimensional space. However, due to physical si...
