Sound Localization in a Sound Field Represented by Spherical Harmonics
Sound localization is an important aspect in human hearing, with interaural time difference (ITD) and interaural level difference (ILD) as two binaural cues that complement each other in this goal. Head related transfer functions (HRTFs) can be used to estimate and analyze these cues, where an HRTF representation in the spherical harmonics domain has recently been suggested for analysis. The ai...
متن کاملInfluence of reflecting plane having finite surface density on sound power level of reference sound sources calibrated in hemi free-field
The NMIJ, National Metrology Institute of Japan planned to start calibration service for reference sound sources (RSSs) by 2015 and we have been developing the RSS calibration system in accordance with ISO 6926. In our system, hemi-anechoic environment necessary for the calibration is realized by laying down wooden boards on a wire meshed floor of our anechoic room. In this study, we investigat...
متن کاملSound Source Localization Using Non-Conformal Surface Sound Field Transformation Based on Spherical Harmonic Wave Decomposition
Spherical microphone arrays have been paid increasing attention for their ability to locate a sound source with arbitrary incident angle in three-dimensional space. Low-frequency sound sources are usually located by using spherical near-field acoustic holography. The reconstruction surface and holography surface are conformal surfaces in the conventional sound field transformation based on gene...
متن کاملSound field planarity characterized by superdirective beamforming
The ability to replicate a plane wave represents an essential element of spatial sound field reproduction. In sound field synthesis, the desired field is often formulated as a plane wave and the error minimized; for other sound field control methods, the energy density or energy ratio is maximized. In all cases and further to the reproduction error, it is informative to characterize how planar ...
