In this paper, we propose a novel system to localize a sound source in any 2D directions using only two microphones. In our system, the two microphones are asymmetrically placed on a sphere, thus, (1) the diffraction by the sphere and the asymmetrical arrangement of the microphones yield the localization cue including the front-back judgment, and (2) unlike the dummy head system, no previous measurements...
We deal with the problem of direction and distance estimate of sound sources in 3-D space and arrive newly at an exact and direct algorithm from the finite observation both in space and time. We first derive a partial differential equation (PDE) what we call the sound source constraint (SSC). We show that the general solution of the SSC-PDE is a diverging spherical wave from a point source with arbitrary...
