DEMO_BAUMGARTNER2016 - Demo for sagittal-plane localization model from Baumgartner et al. (2016)

Program code:

%DEMO_BAUMGARTNER2016 Demo for sagittal-plane localization model from Baumgartner et al. (2016)
%
%   DEMO_BAUMGARTNER2016 demonstrates how to compute and visualize 
%   the baseline prediction (localizing broadband sounds with own ears) 
%   for a listener of the listener pool and the median plane using the 
%   sagittal-plane localization model from Baumgartner et al. (2016).
%
%   Figure 1: Baseline prediction
% 
%      This demo computes the baseline prediction (localizing broadband 
%      sounds with own ears) for an exemplary listener with outer-hair-cell dysfunction.
