Broadband Acoustic Intensity Direction Estimation with Tight-Frame Cardioid Arrays
Akira Omoto
This study experimentally investigates source-direction estimation from acoustic intensity using paired cardioid microphones, with particular emphasis on well-balanced arrangements…
Acoustic intensity estimation using cardioid microphone pairs in tight-frame configurations
Akira Omoto
This paper investigates acoustic intensity estimation using pairs of cardioid microphones based on the cardioid-cardioid (C-C) method. Unlike conventional pressure-difference techn…
Directional reflection modeling via wavenumber-domain reflection coefficient for 3D acoustic field simulation
Satoshi Hoshika, Takahiro Iwami, Akira Omoto
This study proposes a framework for incorporating wavenumber-domain acoustic reflection coefficients into sound field analysis to characterize direction-dependent material reflecti…
Beamforming in the Reproducing Kernel Domain Based on Spatial Differentiation
Takahiro Iwami, Naohisa Inoue, Akira Omoto
This paper proposes a novel beamforming framework in the reproducing kernel domain, derived from a unified interpretation of directional response as spatial differentiation of the…
