Theoretical and Numerical Evaluation of Sensitivity, SNR and Received RMS Error of A Telescopic Microphone System by Using A Spherical Array

This paper newly proposes a telescopic microphone system that may establish the high sensitivity and SNR, and narrow directivity in 3D-space, by using passive dynamic focusing and spherical wave synthesis with a spherical sensor array. On this system, passive dynamic focusing and spherical wave synt...
