Learning spatial hearing via innate mechanisms

Spherical localiser calibration with a limited head rotation range and a unilateral Teacher circuit.
(A) Evolution of the error in the learned localiser during training. Initially, only a small region around the peak response can be accurately estimated (blue region), but over training time the area of accuracy expands to cover the entire space. (B) The approximated 3D sound response of the right ear of the KEMAR manikin, showing the peak response at elevation=, azimuth=
on the spherical cap.
