Monaural Sound Localization Based on Reflective Structure and Homomorphic Deconvolution
The asymmetric structure around the receiver provides a particular time delay for the specific incoming propagation. This paper designs a monaural sound localization system based on the reflective structure around the microphone. The reflective plates are placed to present the direction-wise time delay, which is naturally processed by convolutional operation with a sound source. The received si...
متن کاملImproving the efficiency of deconvolution algorithms for sound source localization.
The localization of sound sources with delay-and-sum (DAS) beamforming is limited by a poor spatial resolution-particularly at low frequencies. Various methods based on deconvolution are examined to improve the resolution of the beamforming map, which can be modeled by a convolution of the unknown acoustic source distribution and the beamformer's response to a point source, i.e., point-spread f...
متن کاملReliability Measurement of Time Difference of Arrival Estimations for Multiple Sound Source Localization
Time Difference Of Arrival (TDOA) estimates are used for passive acoustic single sound source localization with microphone arrays. The technique of choice in most systems for TDOA estimation is the Generalized Cross-Correlation (GCC) method [1]. For a multi-sound source scenario, cross-correlation terms of the active sound source signals as well as noise and reverberation effects complicate the...
